Abstract

Because of their unique amorphous structure, metallic glasses （MGs） exhibit better corrosion resistance compared with traditional crystalline metals and alloys. Thus, MGs have broad application prospects as novel corrosion-resistant materials. The research progress of corrosion resistance of MGs was summarized. The influence factors, such as the alloy composition, microstructure, preparation method, corrosion environment, surface state, stress state etc. on the corrosion resistance of MGs were introduced. The routes to improve the corrosion resistance of MGs were proposed. Finally, the future development trends of corrosion resistance of MGs were discussed and prospected.
