采用涂抹的方法将四元系合金Ｎｉ－Ｃｒ－Ｂ－Ｓｉ系之一的“ＰＳＲ—１”涂层合金涂覆在零部件基体上，在１．３３Ｐａ低真空钼丝炉中熔烧，使涂层与基体之间形成牢固的冶金结合，可提高零件表面在高温燃气中的耐磨、耐蚀性。与堆焊等工艺相比，低真空熔烧涂层工艺具有许多优点
The “PSR-1” coating alloy, which is one of the quaternary alloy Ni-Cr-B-Si systems, was coated on the component base body using a smear method and was melted in a 1.33 Pa low- A strong metallurgical bond between the coating and the substrate improves the wear and corrosion resistance of the part surface in hot gas. Compared with surfacing and other processes, low vacuum sintering process has many advantages
