Research progress on preparation technology of molybdenum disilicide coating

Molybdenum disilicide (MoSi₂) coating has the excellent high-temperature oxidation resistance which is widely used as a protective coating of various materials. Based on the current research status of MoSi₂ coatings at home and abroad, the preparation methods of MoSi₂ coatings, such as plasma spraying, pack cementation, slurry method, molten salt method, magnetron sputtering, chemical vapor deposition, laser cladding method, and spark plasma sintering method, were introduced in detail, and the advantages, differences, and shortcomings of those preparation methods for the MoSi₂ coatings were summarized. The improvement and development of the MoSi₂ coating preparation process were also prospected.
