| Abstract Scope |
Metallic glass coatings are known for their exceptional wear and corrosion-resistant properties, making them a subject of considerable interest in both technological and scientific domains. Recently, there has been significant attention on Fe-based metallic glass composite coatings due to their outstanding mechanical strength and corrosion behavior. This study utilized atmospheric plasma spraying (APS) to fabricate metallic glass composite coatings (Fe-10Cr-10Mo-4B-2C-4P, wt.%) across a range of power inputs. The research systematically explored the impact of spraying power and coating thickness on the coatings' microstructure, phase evolution and its subsequent effects on corrosion resistance. Findings revealed that higher spraying power and more coating thickness led to decreased porosity but increase in crystallinity. Decrease in Porosity enhances the corrosion resistance but increase in crystallinity diminishes the corrosion resistance of the coating. Optimised value of porosity and crystallinity dictates the corrosion behavior. |
