摘要
对等离子束表面冶金涂层技术与其他相近技术进行了比较。等离子束表面冶金涂层技术是一种快速非平衡冶金反应过程,类似粉末冶金,原则上可不受组成物的相溶性、熔点、密度等性质的限制,因此不需要预制合金雾化粉,可利用任意粉末的任意配比,获得通常冶金方法不能得到的(组织)物相。等离子束表面冶金涂层技术效率高,操作简便,成本低,应用前景广阔。
The technology of plasma-jet surface metallurgy with the else corresponding technology such as plasma build-up welding technique is compared. Plasma-jet surface metallurgy is a kind of rapid,non-equilibrium metallurgical process,which is similar to powder metallurgy. The process can not be restricted by consistency, melting point, density of constituents, so prealloy powders are not needed. And it can obtain some special structures and phases in random powder and random match. Plasma-jet surface metallurgy has such characteristics as high efficiency, simple operation, low cost, and has extensive application prospect.
