Abstract

Abstract: Due to high demand of titanium and its alloys in modern manufacturing sectors, the high reactivity, poor conductivity and its functionality with other materials is still cumbersome. Therefore, it's very imperative to study the tribological, thermal and wear behavior of Ti6Al4V alloy against other effective materials like carbides etc. In this holistic work, the pin on disc tests were conducted on Ti6Al4V alloy against PVD-Al00.55 Ti 0.45 N coated carbide pin. Then, the contact temperature, surface topography and wear behavior of pin and material were studied with the help of Scanning Electron Microscope (SEM). The results reveal that the effect of sliding distance on friction coefficient value is very low. On the other hand, the micrographs of wear surface reveal that the sliding distance plays a major role in generation of abrasion marks with adhesive joints as well cold weld junctions. Further, the results of friction coefficient values and the interquartile range (IQR) confirmed the satisfactory range of 14%. Moreover, the average coefficient of friction values were obtained in the range of −7.2–4.6%. Highlights: Tribological, thermal and wear behavior of the pair TI6Al4V-sintered carbide with AlTiN coatings. Pin on disc tests were performed against commercially used TI6Al4V alloy and sintered carbide pin. Surface morphology, contact temperature and wear characteristics were investigated.
