磨损是金属材料失效重要因素之一。因此,提高金属材料耐磨性就具有重要意义。提高耐磨性的途径很多,其中有一大类是在金属工件表面包敷一层耐磨性较高的材质,以便延长工件使用寿命。组成合金堆焊是一种新的耐磨堆焊工艺,与其它工艺相比,它具有如下一些特点:①表面堆焊层由具有高耐磨的WC硬质点组成,WC排列致密、均匀,堆焊层厚度由几毫米到20毫米之间,任意调整;②堆焊层兼有高
Wear is one of the important factors of the failure of metallic materials. Therefore, to improve the wear resistance of metal materials is of great significance. There are many ways to improve the wear resistance. One of the major types is to coat the surface of the metal workpiece with a material with high abrasion resistance so as to prolong the service life of the workpiece. Composition of alloy surfacing is a new wear-resistant surfacing process, compared with other processes, it has some of the following characteristics: ① surfacing layer consists of hard wear resistant WC hard points, WC arranged dense, uniform, Surfacing layer thickness from a few millimeters to 20 millimeters, arbitrarily adjusted; ② surfacing both high
