摘要

One of the most effective ways of shaping the operating parameters of functional elements is to modify the properties of a surface layer using modern technologies of surface engineering. The most prospective directions in the development of surface engineering solutions are nanomultilayer coatings which enable effective shaping of surface layer properties. A very important factor in designing properties of PVD coatings, apart from their chemical composition, is their microstructure. The paper presents the influence of the microstructure of the nanomultilayer AIN-CrN-TiN coating on their tribological properties at elevated temperature. The research methods were concentrated on the analysis of mechanical properties, microstructure and tribological properties at increased temperature. The studies on mechanical properties included tests on hardness using the nanoindentation method, and tests on adhesion using the scratch-test method. The analysis of microstructure was performed using scanning microscopy. The tribological properties at high temperature were examined using the ball-on-disc method. The authors indicate that the AIN-CrN-TiN layers are characterised by excellent mechanical properties and tribological resistance. In this paper the authors confirm that the microstructure of a nanomultilayer coating is important in shaping the mechanical and tribological properties of a PVD coating.
