自熔性合金粉末氧-乙炔焰喷焊,是用氧-乙炔焰为热源,将具有各种特性的合金粉末喷敷到工件表面上的一项新工艺。与喷涂及堆焊相比,金属喷涂的涂层与工件呈机械结合,涂层呈多孔性,而电弧堆焊的焊层与基体材料的冲淡率大,焊层表面不均匀,焊后需机加工时,切削余量较大,浪费材料较多。氧-乙炔焰喷焊则介于喷涂和堆焊之间,既能与喷涂一样使焊层薄而光滑,又如堆焊一样,焊层呈渗透结合,强度较高,且焊层与基材冲淡率基本不存在。只要选择各种不同性能的合金粉末,就能使工件表面达到HB200～
Self-fluxing alloy powder oxy-acetylene flame spray welding, is the use of oxygen - acetylene flame as a heat source, the alloy powder with a variety of characteristics is sprayed onto the workpiece surface of a new technology. Compared with spraying and surfacing, the metal sprayed coating is mechanically combined with the workpiece, the coating is porous, and the arc welding of the welding layer and the matrix material dilute the rate of large, uneven welding surface, after welding machine Processing, cutting allowance larger waste of materials more. Oxygen-acetylene flame spray is between the spray and surfacing, both as the same as the spray and the weld layer is thin and smooth, as the same surfacing, the weld layer is osmotically bonded, high strength, and the welding layer and the substrate Basically, dilution does not exist. As long as the choice of a variety of different performance alloy powder, you can make the workpiece surface HB200 ~
