Research Progress on the Corrosion Behavior of Metallic Glass and Its Composites

In the context of growing demands for durable, high-performance materials capable of operating in increasingly harsh environments, metallic glasses and their composites have attracted extensive research interest. Metallic glasses and their composites exhibit remarkable advantages for structural applications in a wide range of environments due to their unique disordered atomic structure, high strength, and excellent physicochemical properties. In recent years, their corrosion behavior has garnered broad attention, with particular emphasis on corrosion resistance under complex service conditions becoming a central research focus. This review provides a comprehensive examination of the corrosion behavior of metallic glass and their composites. It surveys the reaction mechanisms and characteristic features of these materials in diverse corrosive media, analyzes the factors that govern their corrosion resistance, and summarizes strategies for optimizing their corrosion performance, with the aim of promoting their application in real-world service environments.
