Abstract

Ti/MoS2 coating was deposited by pulse laser deposition technology on Al-Si substrate. The microstructure, elemental analysis, nanotribological behaviour of coating was investigated. The coating was composed of Ti, Mo, S and O with typical diffraction peak around 2? range from 30o to 70o. Nanoscratch with ramp loading was performed at low loads. The scratch test with ramp normal loading was analyzed for failure of coating in three ranges, Viz., range A, range B and range C. Scratch test result shows that the peeling of coating occurred at the normal load of 1327.75 µN and the lateral load of 75.96 µN. Nanowear with 2, 4, 6, 8, 10 number of cycles was performed at low load 100 µN. Nanowear results shows that wear rate decreases with increase in wear cycles, which attributed the self lubricating property of Ti/MoS2 coating. Also, Ti/MoS2 coating display smooth wear path with no debris and cracks, which attributed plastic flow of coating around impression. Thus, mode of wear mechanism is mainly ductile and abrasive.
