摘　　要：针对民用航空发动机激光选区熔化制件适航符合性验证需求,总结了激光选区熔化技术在航空发动机中的应用现状,分析了激光选区熔化制件适航符合性验证相关参考资料要求,研究了激光选区熔化航空发动机制件适航符合性验证方法。目前,国外已有激光选区熔化航空发动机制件通过了适航审定,而我国在该领域仍处于起步阶段。基于相关参考资料及传统工艺适航符合性验证方法,认为激光选区熔化航空发动机制件的适航符合性验证方法主要应包括:建立激光选区熔化材料规范、认证激光选区熔化工艺、鉴定激光选区熔化成形材料是否合格及确定设计用材料性能。Motivated by the demand of airworthiness compliance of civil aeroengine components fabricated using selective laser melting(SLM)technique,the applications of SLMed aeroengine components were summarized.Additionally,reference related to airworthiness compliance of SLMed components were analyzed.Meanwhile,airworthiness compliance demonstration method of SLMed aeroengine components was investigated.Presently,some SLMed aeroengine components have passed the airworthiness certification in foreign countries.However,China is still in the initial stage in this field.According to the related reference and airworthiness compliance demonstration method of aeroengine components manufactured through traditional processing techniques,the airworthiness compliance demonstration method of SLMed aeroengine components should mainly contain the following parts:establishment of selective laser melted material specifications,certification of selective laser melting process,identification of material quality and determination of material properties.
