Research Progress Of Anti-Titanium Flame Retardant Abrasion Resistance Coating For Aero-Engine Titanium Alloy Compressor Assembly

This paper described the application advantages of titanium alloy in aviation engine and the problems of "titanium fire", and introduced the solutions to "titanium fire", :such as flame retardant titanium alloy, flame retardant coating and flame retardant abrasion coating. The research status of flame-retardant and wearability coatings, including the evaluation criteria of their flame-retardant and wearability, and the mechanism research of flame-retardant and wearability coatings were emphatically introduced. Finally, the research trend and development direction of flame-retardant and wearability coatings for titanium alloys in the range of 600 similar to 750 degrees C in the future were pointed out.
