中文摘要: 本文以铜铝合金粉和聚苯酯为原材料， 添加粘结剂， 采用机械团聚复合工艺制备铜铝聚苯酯复合粉末；
采用大气等离子喷涂工艺制备的铜铝聚苯酯封严涂层组织均匀， 聚苯酯和孔隙占比 45.3%， 涂层硬度为 56.3
HR15Y、 结合强度 ≥6.9MPa、 650℃下抗热震性能良好， 涂层在 96 小时室温中性盐雾试验外观评级达到 4 级， 可
满足航空发动机对气路间隙控制封严涂层的要求。
Abstract:In this paper, Cu-Al alloy powders and polyester were used as raw materials, and then the binder was
added. Mechanical aggregate composite process has been adopted to prepare the aluminum bronze polyester
(CuAl-PHB) composite powder. The CuAl-PHB coatings prepared by atmospheric plasma spraying (APS) were
uniform. The ratio of polyester and porosity was 45.3%. The coating hardness was 56.3 HR15Y; the bonding
strength was 6.9 MPa, which exhibited excellent thermal shock resistance at 650℃ . The appearance of the coating
reached grade 4 in 96 h room temperature neutral salt spray test. The coatings can meet the requirements of aeroengine seal coating for air-path clearance control.
