摘要:

本文描述了钛合金在航空发动机的应用优势及出现的“钛火”问题,并介绍了解决“钛火”的方案,如阻燃钛合金、阻燃涂层及阻燃可磨耗涂层等。着重介绍了阻燃可磨耗涂层的技术研究现状,包括其涂层阻燃可磨耗性的评价标准以及阻燃可磨耗的相关机理研究。最后指出了钛合金阻燃可磨耗涂层未来在600-750℃区间的研究趋势和发展方向。

Abstract:

This paper describes the application advantages of titanium alloy in aviation engine and the problems of "titanium fire", and introduces 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 600-750℃ in the future were pointed out.
