Abstract

Refractory metals and their alloys have excellent properties such as high-temperature strength and corrosion resistance. It is widely used in aerospace, electronics industry and other fields. However, refractory alloys are prone to oxidation and failure in high-temperature service environments. The preparation of a MoSi₂ antioxidant coating is an effective method for improving the protective ability of refractory metals at high temperatures. However, although MoSi₂ coatings have many advantages, it is difficult to meet the increasingly stringent service requirements. To address these challenges, researchers have used different elements to modify a single MoSi₂ coating and improve its overall oxidation resistance. In this study, the roles of one or more elements (Si, B, N, Zr, Al, W, Hf, Y, Ti and Cr) in MoSi₂ coatings are systematically reviewed. Simultaneously, the mechanism of single or multiple synergistic modification of MoSi₂ coatings with different elements was discussed. Finally, the development prospects of MoSi₂ coating modification of refractory metals and their alloys are discussed.
