等离子喷镀技术是在第二次世界大战后发展起来的。这是一种利用电弧产生等离子体,再用等离子体熔化高熔点金属及陶瓷粉末,并以高速向基体上喷吹而生成涂层的技术。发生离子体的热源是氩、氦、氮、氢等气体。其火焰温度可达15000℃,甚至可以达30000℃。最初美国是利用这种技术对喷气发动机耐高温零部件材料进行涂层以提高产品的耐磨及耐热性能。近几年来等离子喷镀装置及材料的研究工作进展迅速,应用领域
Plasma spraying technology developed after the Second World War. This is the use of arc plasma generation, and then use plasma to melt high melting point metal and ceramic powder, and high-speed injection to the substrate to form a coating technology. Generated ion heat source is argon, helium, nitrogen, hydrogen and other gases. The flame temperature up to 15000 ℃, and even up to 30000 ℃. Initially the United States is the use of this technology to jet engine parts high temperature coating materials to improve product wear resistance and heat resistance. In recent years, plasma spraying equipment and materials research work is progressing rapidly, applications
