Article Citation - Scopus: 3Investigation of a Digital Hydraulic Valve Operated by Servo Motors(Dr D. Pylarinos, 2021-12-11) Ozalp, A.F.; Polat, R.; Cetinkaya, C.; Cetin, M.H.This paper describes a new type of digital hydraulic valve run by two servo motors. Digital hydraulics is a cuttingedge technology, which saves more exhausted energy than conventional hydraulic valves. It includes conventional valves, but its working principle is different. Similar or different size valves constitute a digital hydraulic valve assembly. When the assigned valves are opened, a certain amount of flow is obtained from the output of the valve assembly. To control a digital hydraulic valve, Pulse Number Modulation (PNM) Control technique is used for equal valve flow rates, while Pulse Code Modulation (PCM) is used for different valve flow rates. Valves are exerted by independently launched electric coils. Previous studies used controller board and external power booster circuits for coils. In this study, a new type of digital hydraulic valve is designed, manufactured, and tested with the PNM method. The studied valve body has two different valve groups. Every group includes 16 equal valves and 1 camshaft rotated by 1 servo motor. The servo motors are controlled by a PLC. The calculated performance index is found to be 5.1ms which is similar to the results of previous studies. The experimental results showed that the cam and servo motor controlled digital hydraulics is applicable to variable speed control hydraulic systems. © 2021, Dr D. Pylarinos.

Sabri; Çetin, M. HuseyinIn this study, the synthesis of hydrothermal carbon (HTC) lubricant and its usability as a lubricant under hot industrial conditions were investigated. In this context, the characterization of HTC produced from organic sources at low cost and in a short time was performed, and its tribological performance was analysed in detail. HTC produced by the hydrothermal carbonization method was characterized through SEM images and EDS analysis. To determine the effect of HTC on friction at different temperatures, HTC was subjected to a pin-on-disc wear test with AA5754 material. The effect of various lubricants, temperatures, blank holder pressure, and forming speed parameters on the forming force for the analysis of the tribological effect of HTC on deep drawing processes were statistically analysed. The performance of HTC was compared with Teflon, fullerenes, graphene, and carbon nanotube (CNT) materials. According to the results obtained from wear tests, the lowest friction coefficient value was achieved in the presence of fullerenes as the lubricant, and as the temperature increased, the friction coefficient decreased. It was observed that HTC exhibited lower performance in the wear test compared to fullerenes due to oxidation. When the effect of deep drawing parameters on the forming force was analysed, it was concluded that the most effective parameters were temperature (72.32%) and lubricant (20.89%). According to the S/N analysis results, the minimum forming force was obtained under the conditions of solid Teflon lubricant, 250 degrees C temperature, 15-bar blank holder pressure, and 2 mm/s forming speed. The tribological performance difference between HTC and Teflon is at the 1% level. The results demonstrate the potential industrial usability of HTC as a lubricant.Article Citation - WoS: 2Citation - Scopus: 2Effect of Shot-Peening Process and Nanoparticle-Added Lubricant on the Tribological Performance of Aluminium-Based Sliding Bearing Material(Wiley, 2024-08-27) Korkmaz, Şeyma; Çetin, M. Hüseyin; Simsir, Hamza; Ünal, Okan; Temel, FarabiIn this study, it is aimed to increase the wear and fatigue performance of aluminium-based sliding bearing material by using silver nanoparticles (AgNPs) added lubricant and shot-peening process. The main purpose is to minimise the wear of the bearing material by penetrating AgNPs added lubricants into the rough surfaces formed by shot peening. Almen intensity, coverage and shot size parameters in the shot-peening process were analysed in terms of hardness, surface roughness and fatigue strength. The shot-peened aluminium bronze was subjected to wear experiments under dry, pure water and AgNPs added lubricant conditions. The wear test results were analysed in terms of friction coefficient, wear volume and surface roughness parameters, and the interaction of lubricant and shot-peening parameters was evaluated. According to the results of the shot-peening experiments, the Almen intensity was the most effective parameter in terms of hardness and surface roughness (91.62%). It was concluded that the hardness value was 8% higher at high Almen (12-14A) intensity compared with low Almen intensities, and the shot-peening process could increase the fatigue strength by similar to 21 times. According to the wear tests, the most effective parameters were 4-6 Almen intensity and AgNP-added lubricant.Article Citation - WoS: 1Citation - Scopus: 2Investigation of Wear and Corrosion Resistance of Wc-Coated Pearlitic Railway Steel in Dry and Wet Conditions(Elsevier Sci Ltd, 2025-08-01) Orak, Abdulkadir; Korkmaz, Seyma; Cetin, M. HuseyinIn this study, the effect of WC coating on the tribological performance of R260 rail steel was investigated by roller-on-plate wear tests and potentiodynamic polarisation corrosion tests carried out in dry and pure water environments. The High-Velocity Oxygen-Fuel (HVOF) method was used for the coating process. The tests were conducted with a weight of 40 N and a sliding speed of 0.03 m/s. An Ag/AgCl reference electrode was also used for corrosion tests in a 3.5 % NaCl solution. To produce cyclic polarisation curves, the experiments were carried out at a scan rate of 1 mV/s within a potential range of +/- 0.25 V. The effect of WC coating on the wear performance of rail steels was analysed quantitatively with the friction coefficient and volume loss parameters and visually with SEM and 2D-3D topography images. The effect of the coating on the corrosion performance was evaluated numerically with the corrosion potential, corrosion current intensity, and corrosion rate values, as well as elementally and visually with SEM and EDX images. Wear test results showed that the wear volume in WCcoated rail steels decreased by 43.07 % and 46.94 % compared to uncoated rail steels in dry and wet conditions. Corrosion test results showed that the corrosion rate of WC-coated rail steels was lower compared to uncoated rail steels, and the corrosive effect spread to a smaller area.Article Citation - WoS: 2Citation - Scopus: 1Investigation of Tribological Behavior of Coated and Untreated Rail Steels Under Wet Conditions(Iop Publishing Ltd, 2024-05-23) Çetin, M. Huseyin; Kondul, BilgehanRails are exposed to more stresses, especially in the regions of narrow radius curves and switch passages. Therefore, the tribological features of these regions are important. In this study, the effect of boronization on tribological properties was examined. For this purpose, experiments were carried out on samples boronized at 800 degrees C for 2 h and 8 h and on untreated samples. With these experiments, the friction coefficient, volume loss and surface roughness values of the samples under wet conditions were examined. In addition, the microstructures of the material after boriding were observed by SEM and EDX. The variance and regression method (ANOVA) was used for the statistical analysis of the experimental results. After SEM examinations, a coating layer of similar to 22 mu m (FeB) and similar to 48 mu m (FeB+Fe2B) were obtained on the surface of the rail steels boronized for 2 and 8 h, respectively. The microhardness of the rail steels, which was similar to 300 HV for the untreated sample, increased to similar to 1900 HV and similar to 2400 HV with the boronizing process boronized for 2 and 8 h, respectively. According to the ANOVA results, the effects of the boronizing process on the decrease of the friction coefficient and the volume loss were calculated as 42% and 46%, respectively. Finally, according to the corrosion results, the corrosion resistance of the boronized rail steels decreased with the boride layer formed.Article Determination of Optimum Test Parameter Level Ranges for Machining Processes(Dr D. Pylarinos, 2024-06-01) Alabayed, M.A.K.; Alghatous, S.A.S.; Ozarpa, C.; Korkmaz, S.; Cetin, M.H.; Basher, I.S.A.In this study, the ideal experimental design planning for the machining process was investigated. Two experimental designs were created by differentiating the parameter levels considered in the drilling process of stainless-steel. Close and far-level designs were obtained by creating 20% and 40% differences between the parameter levels. In the experimental system prepared according to the Taguchi method, surface roughness and cutting forces were measured as the output parameters. The results were analyzed statistically by optimization, analysis of variance and correlation analysis, and visually by chip morphology examination. According to the findings, it was determined that a 20% difference between the parameter levels was more appropriate in terms of experimental system stability, statistical data significance, and chip morphology. © by the authors.Master Thesis Nano Silisyum Dioksit Kolloidal Süspansiyonunun Tribolojik Performans Ajanı Olarak Kullanılabilirliğinin İncelenmesi(2025) Küstük, İrem; Çetin, Muhammet HüseyinSoğutma ve yağlama sıvıları metal işleme, otomotiv, havacılık gibi birçok sektörde kullanılmaktadır.

Hassas dökümde parafin malzemeden üretilen özel olarak tasarlanmış bir model, metalik esaslı kalıplar ve seramik esaslı kabuklar kullanılmaktadır. Mum enjeksiyon kalıbı yapımı, mum model oluşumu, model ağacı oluşumu, seramik kabuk oluşumu, mum giderme, sinterleme, döküm, kabuk kırma, ürün temizleme/zımparalama aşamalarından oluşan hassas dökümün her bir aşamasının nihai ürüne etkisi vardır. Bu çalışmada hassas dökümde en önemli adımlardan bir tanesi olan seramik kabuk üretimi aşamasındaki kurutma süresi- katman sayısı parametrelerinin optimizasyonu ve optimum şartlar sağlandıktan sonra kimyasal kompozisyona ekleme yapılarak mekanik anlamda daha kullanışlı kabuklar elde edilmesi, fire oranının azaltılması amaçlanmıştır. Çalışmada katlar arası kurutma süresi ve kat sayısının etkisi incelenmiştir. Kurutma süreleri 30, 45, 60'ar dakika artırımlı şekilde dikkate alınmış ve kurutma süresi arttıkça üç noktalı eğilme deneyi ile ölçülen kırılma modülü değerinin arttığı belirlenmiştir. Kat sayısı için 5, 6, 7 kat sayılı numuneler değerlendirilerek kat sayısı arttıkça kabul mukavemeti değerinin arttığı gözlemlenmiştir. Yüzey pürüzlülük değerleri incelendiğinde kurutma süresi ve katman sayısının yüzey pürüzlülüğünde anlamlı bir etkisi olmadığı görülmüştür. İlaveten çalışma kapsamında, çamur içerisindeki bakteri durumunun mekanik özellikleri etkilediği düşünülerek dezenfektan ilavesi ile kırılma modülü ilişkisi incelenmiştir. Dezenfektan ilaveli çamurda bakteri sayısında düşüş gözlemlenmiş ancak dezenfektan ilavesinin mekanik özelliklere etkisinin olmadığı tespit edilmiştirArticle Citation - WoS: 28Citation - Scopus: 29The Effect of Halloysite Nanotube Modification on Wear Behavior of Carbon-Aramid Fiber Reinforced Hybrid Nanocomposites(WILEY, 2021-11-18) Çetin, Mehmet Emin; Baştosun, Yusuf; Tatar, Ahmet Caner; Çetin, Muhammet Hüseyin; Demir, Okan; Önal, Gürol; Avcı, AhmetIn this study, the carbon-aramid fiber reinforced hybrid composites are fabricated using a vacuum-assisted hand lay-up method using halloysite nanotubes (HNTs) modified epoxy matrix. Ball-on-disk wear tests are performed to analyze the tribological effect of neat and HNTs-added specimens at 10, 15, and 20 N loads and 1 m/s sliding speed. Additionally, the wear rate and friction coefficient results are obtained to investigate the effect of the HNTs on the tribological behavior of hybrid composites. The wear mechanism of neat and nanocomposite specimens is specified by scanning electron microscopy (SEM) images, and the elemental analysis of worn surfaces is performed using EDX. Finally, the surface morphology is evaluated with 3D topography images. Additionally, thermal camera images are used to identify the thermal conductivity effect of HNTs on wear. The wear test results show that HNTs-addition to composite decreased the friction coefficient by 9%, 10%, and 11% for 10 N, 15 N, and 20 N loadings, respectively. The wear rate is also decreased average by 75% for wear loadings. Surface form images acquired from 3D topography support the enhancement in the friction coefficient and wear rate values. Furthermore, thermal camera images show that thermal conductivity improvement on the contact region is attributed to well thermal properties of HNTs. Furthermore, the solid-lubricant characteristic of HNTs as forming tribofilm is determined as the main reason for the enhanced tribological performance of nanocomposites. Finally, a detailed wear mechanism is proposed to explain the wear behavior of HNTs-added carbon-aramid hybrid composites based on SEM images.Article Citation - Scopus: 1Investigation of Nano-Copper Added Cutting Fluid Performance on Milling Process by Using the Bees Algorithm and Experimental Design Methods(IOP Publishing Ltd, 2025-11-01) Sirvan, Onur Can; Cetin, M. Huseyin; Turkoz, Mevlut; Temel, Farabi; Duzcukoglu, Hayrettin; Koklu, Ugur; Ozcelik, BaburIn this study, the tribological performance of copper nanoparticles coated with different ligands added to the metal cutting fluid as an additive was investigated. Copper, which has a high heat transfer coefficient and self-lubricating properties, is aimed at reducing the temperature in the chip area and reducing wear by acting as a lubricant, increasing tool life and surface quality of the processed material. The study was carried out in four stages. In the first stage, UV absorbance, STEM, wettability, and PSA analyses were performed on gelatine, cellulose, and PVP-coated copper nanoparticles synthesised by the chemical reduction method. According to the results of the analysis, the best ligand was gelatine. In the second stage, a pin-on-disc wear test was performed under different speeds (0.5, 0.7, and 0.9 m s-1), loads (10, 20, and 35 N), and ligand parameters. According to the friction coefficient, weight loss, and 3d topography images obtained from the wear experiments, the ligands that showed the best performance were gelatine, PVP, and cellulose, respectively. In the third stage, the chip removal process was carried out using the response surface method at different speeds, feeds, depths, and nano-fluid environments. In the 3d topography analyses, the best result in terms of surface roughness was obtained in the boron solution, and the best result in cutting forces was obtained in the gelatine-coated copper nanoparticle (CuNP-Gel) environment. In the tool wear experiment, boron solution and CuNP-Gel were used as coolant/lubricant liquids, and it was observed that the tool wear occurs more slowly in the CuNP-Gel environment.
