Structure of Al-AlN Composite Coatings Obtained by Arc-PVD Method

Abstract:

In this paper the investigations concerning deposition of aluminium and aluminium nitride coatings by Arc-PVD method were presented. The tests were done on samples made of martensitic stainless steel EI962 (11H11N2W2MF) type. The aluminium base coatings are corrosion resistant in many environments and are anodic in comparison with most of steel. For this reason those coatings are expected to form a replacement for cadmium galvanic coatings. The main parameters of aluminium base coatings deposition by Arc-PVD processes were presented. Influence of Arc-PVD parameters on Al-AlN composite coatings structure was described. The models of Al-AlN composite coatings and Al/Al-AlN multilayer coatings as well as the scanning electron microscope microstructure and profile chemical composition by GDOS analysis of the coatings deposited on EI962 stainless steel were shown.
