Structure and Properties of Thin Layer – Substrate on High Speed Steel with Different Thickness of TiN
Keywords:TiN coating, PVD technology, hardness, scratch test
The main application of TiN coating deposited on metallic materials by Arc – PVD method is to increase the wear resistance. The properties of TiN coating are related to the properties of the substrate, technological parameters, microstructure, thickness, adhesion and hardness of the film. This paper presents the results of mechanical property measurement of 2 mm and 4 mm thick TiN coatings deposited on high-speed steel. The hardness was measured by nanoindentor and the adhesion by scratch test. The microstructure of TiN coating was evaluated by SEM microscopy.
