对于很多工农业元件,要求其在保证低成本的同时具备耐磨性和抗断裂性。本文表明,用柔韧性粉末注射成形适合复合零件的生产。其技术要点是将硬而耐磨的粉末冶金合金注射到锻钢基体表面上。因此,材料表层和芯部材料可以分别选择,从而获得最佳的复合性能。使用注射成形方法生产几何形状复杂的元件对人们具有很大的吸引力。选用的注射材料为钨—铬—钴合金 Stel- For many industrial and agricultural components, it is required to wear at the same time with low cost and fracture resistance. This article shows that the use of flexible powder injection molding for the production of composite parts. The technical point is that the hard and wear-resistant powder metallurgy alloy is injected onto the surface of the forged steel substrate. Therefore, the material surface and the core material can be selected separately to obtain the best composite properties. The use of injection molding to produce geometrically complex components is highly attractive to people. The injection material used is tungsten-chromium-cobalt alloy Stel-
