Research progress in preparation and wear corrosion resistance of Fe-based amorphous alloy coatings

Abstract

Fe-based amorphous alloy coatings have emerged as a key area of research in the field of surface engineering due to its high strength， hardness， and exceptional wear and corrosion resistance. This paper provides a comprehensive review of the preparation， performance， and application status of Fe-based amorphous alloy coatings. It also summarizes the fundamental principles of amorphous alloy material design and typical Fe-based amorphous alloy coatings material systems. The focus is on three coating preparation technologies： thermal spraying， cold spraying， and laser cladding. Additionally， it compiles the research progress made in understanding the tribological properties and corrosion resistance of Fe-based amorphous alloy coatings. Furthermore， it briefly outlines the applications of these coatings in military， medical， industrial fields etc. Finally， it is pointed out that in-depth study of amorphous formation， the establishment of specialized material systems while matching the working environment， and the adoption of post-processing or more efficient preparation methods are the development trends for future research work in this field.
