最近,日本钢管公司开发了利用激光制造金属包层钢管的技术。这一技术是在旋转的钢管(基材)表面喷上包覆材料的粉末,再用二氧化碳激光器照射,使粉末及基材的表面熔化,从而形成金属包层。包覆材料以粉末状供给,可自由改变其成份,因此,所制成的钢管具有单一材料所无法比拟的优异耐腐蚀性能和耐磨损性。 例如,在耐高温不锈钢(SUS321H)钢管表面复合具有高耐腐蚀性的50％镍、50％铬的粉末,就可使钢管得到单一材料所无法 Recently, Nippon Steel Pipe Co., Ltd. developed a technology that uses laser to make metal clad steel pipe. In this technique, a powder of coating material is sprayed on the surface of a rotating steel pipe (substrate) and irradiated with a carbon dioxide laser to melt the surface of the powder and the substrate to form a metal cladding. The coating material is supplied in the form of a powder, and its composition is freely changed. Therefore, the manufactured steel pipe has excellent corrosion resistance and abrasion resistance unmatched by a single material. For example, in the high temperature stainless steel (SUS321H) steel surface with high corrosion resistance of 50% nickel, 50% chromium powder, you can get a single steel pipe can not
