Abstract

Adhesion strength of coating is one of the most imperative factors in magnetron sputtering technique. Therefore; exploring the effect of coating parameters on enhancing adhesion strength of coating to substrate is extremely important. In this study, an experimental assessment was carried out to discover the fretting fatigue life of Cr/CrN coated AL7075-T6 alloy with higher adhesion strength to substrate by application of PVD magnetron sputtering technique. A fuzzy logic method was utilized to examine how to achieve higher adhesion of coating regarding to changes in input process parameters including DC power, nitrogen flow rate and temperature for fretting fatigue life Improvement.
