The present work is related to the evaluation of dry sliding wear resistance of a sputtered PVD nanostructured nc-TiN/a-Si3N4 coating, deposited on Stainless steel 316L substrates. X-ray diffraction is used to analyze the nanostructure of the film. The topography of substrates, films and Wore Surfaces were analyzed by profilometry. Film adhesion to the substrate was evaluated by scratch-tests. The surface hardness was measured with a Vickers micro-hardness tester. The wear resistance was evaluated by Pin-on disk under a normal load in the range of 2 to 10 N and a constant tangential speed of 0.15 m/s and reciprocating apparatus with a frequency of 1 Hz and a normal load within the same range established above, both tests in dry conditions. After these tests, on the coating as well as on the counterpart, the wear mechanisms developed were analyzed by Optical Microscopy, the wear tracks were measured and the wear rate was calculated and discussed.
