Enhancing Performance of Improved Wear and Corrosion Resistance in Nickel-Based Super Alloys via Zirconium Coating

Abstract

An essential industrial procedure used to protect base materials from wear, corrosion, and numerous other surface-related degradation phenomena is surface modification via thin film deposition. For their hardness and resistance to corrosion, thin hard coatings like zirconium (Zn) coatings have been utilized to make tool dies. Super alloys based on nickel are provided in a heat-treated state, often hardened and tempered to meet the needs of a certain application. Precision items called tool dies have final shapes and dimensions that must be accurate to within a few microns in order to produce parts. The chemical composition affects the machinability of the nickel-based super alloys in distinct ways. This research paper aims to cover nickel-based super alloy components with zirconium. It is crucial to demonstrate how various sputtering circumstances contribute to the necessary microstructural characteristics. Sputtering parameters efficiently control the thin film's microstructural properties. The current work attempts to optimise the zirconium thin film coating on a nickel-based super alloy by examining the influence of process parameters on coated surface attributes. The Pin on Disc and Salt Spray Test as well as the Vikers Hardness Tester will be used to evaluate the coating's properties.
