Abstract

Abstract The aim of the presented paper was to describe the wear mechanisms operating at the small length scale in multilayer coatings subjected to a mechanical testing. A hybrid PLD system (Pulsed Laser Deposition connected with magnetron sputtering) was used for the multi-layer coating deposition. Coatings were subjected to indentation, ball-on disc wear and scratch adhesion tests. Microstructure of the as-deposited coating and after mechanical tests was studied using the Scanning (SEM) and the Transmission (TEM) Electron Microscopes. The research work revealed that application of innovative multilayer coatings may allow to predict their life time and to steer their properties.
