Investigation of wear, surface, metallurgical and mechanical properties of Ti6Al4V alloys coated with PVD method

In this study, the PVD method coated cylindrical specimens produced from Ti6Al4V alloy with AlCrN, TiAlN, TiN, TiSiN coatings at different thicknesses. Profilometer tests were applied to determine the surface properties, such as coating thickness and surface roughness of the coated specimens, and microhardness and wear tests were applied to the specimens to determine the mechanical properties. In the profilometer measurements, the coating thicknesses were measured between 1- 5 mu m and the surface roughness values between 0.4 and 0.8 mu m. From the microhardness and wea r results, it was determined that thin-coated specimens gave better results than thick-coated specimens. While TiAlN had the best performance in microhardness and wear tests, this coating was followed by TiSiN, TiN and AlCrN coatings, respectively. ; Scientific Research Projects Coordination Unit of the Kastamonu University [KU-BAP01/2018-83] ; We would like to thank the Scientific Research Projects Coordination Unit of the Kastamonu University, within the scope of the project supported with registration no: KU-BAP01/2018-83, to Inan Coating company and its employees, where the coating processes were carried out, to Pamukkale University, Faculty of Technology, Metallurgy and Materials Engineering Department, where the abrasion tests were carried out, and to Gazi University where the profilometer analysis was carried out.
