Hardened Enhancement Investigation of Al-Zr-N Coating by EBM Technique: A review

Abstract

The purpose of this research is to examine the Al-Zr-N coating applied to the E19 steel alloy by physical vapour deposition using an electron beam. The physical vapour deposition processes used to create layered [Al-Zr-N] coatings and the structures, wear resistances, and corrosion behaviours of these materials. In order to examine the coating structures, surface roughness, micro-hardness, micro-abrasion, and pin on disc were used. One of the residual stress elements that can lead to failure mechanisms for suitable coatings is thermal stress. The mechanical characteristics of the coating, including its deposition temperature, young's modulus, thermal expansion coefficient, and substrate and coating thickness, were investigated using a validated computational simulation in this paper.
