摘　　要：本文研究了用不同热处理制度后Cu Al10Fe5Ni5雾化粉末经冷喷涂所得涂层的相组成、硬度、形貌、结合强度等相关性能,并进行了相关的空蚀性能测试。结果表明:雾化后的Cu Al10Fe5Ni粉末经7小时、600℃的退火后,进行冷喷涂所得到的涂层质量更高,结合强度更好,具有比船用GL-A钢更好的抗气蚀性能。This study investigates the formation, bonding strength, hardness and anti-cavitation property in cold spraying and attainable properties by using atomized and by heat-treatment optimized CuA110Fe5Ni5 powders. The results indicated that cold spraying coatings prepared by powder annealed for minimum 7 h at 600 ℃ , the cavitation resistance of the cold sprayed coatings is significantly better than that of the ship building steel GL-A.
