摘要
阻燃性能是衡量航空发动机钛火安全的关键性能指标,通常采用钛合金材料/构件抵抗热自燃、点燃和扩展燃烧的能力进行综合评价。针对高性能航空发动机对先进高温钛合金的需求,在回顾近期抗点燃性能和抗燃烧性能试验技术研究基础上,重点从抗热自燃性能的层面介绍阻燃钛合金、高温钛合金及钛铝金属间化合物的非等温氧化行为及阻燃机理的研究进展,并对未来发展方向进行展望。
Fireproof property is a key performance index to measure the safety of aero-engine titanium fire,which is generally evaluated by the abilities of titanium alloy materials/components to resist thermal spontaneous combustion,ignition and extended combustion.Aiming at the demand of advanced high-temperature titanium alloys for highperformance aero-engines,this paper reviews recent experimental studies on ignition resistance and combustion resistance and introduces the research progress of non-isothermal oxidation behavior and fireproof mechanism of fireproof titanium alloys,high temperature titanium alloys and intermetallic titanium aluminides from the aspect of thermal spontaneous combustion resistance.Finally,the future direction of development is prospected.
