以金属、化合物或矿物颗粒为核心,表面包复一至几种金属或合金,称为复合粉末材料。这类材料广泛用于热喷涂技术(如:火焰喷涂、等离子喷涂、爆炸喷涂,及用于粉末冶金、合金配制等。)由于复合粉末是多组份组成,因此,经热喷涂后可形成具有特殊物理,化学和机械性能的涂层。诸如:自结合涂层、耐磨涂层、高温抗氧化涂层、可磨耗封严涂层、隔热涂层和低磨擦自润滑涂层等等。这些涂层广泛用于航空、交通运输、石油、化 Metal, compound or mineral particles as the core, the surface covered with one or several metals or alloys, known as the composite powder material. Such materials are widely used in thermal spraying technology (such as: flame spraying, plasma spraying, explosion spraying, and for powder metallurgy, alloy preparation, etc.) As the composite powder is composed of multi-component, therefore, after thermal spraying can be formed with Special physical, chemical and mechanical properties of the coating. Such as: self-bonding coating, wear-resistant coating, high temperature anti-oxidation coating, abradable seal coating, thermal coating and low friction self-lubricating coating and so on. These coatings are widely used in aviation, transportation, petroleum and chemical industries
