Application of Cu-P pre-alloyed powder in the carcass of diamond tools
-
摘要: 在金刚石工具中添加铜磷预合金粉,热压烧结过程中铜磷预合金粉瞬时液化对铁铜基础粉形成钎焊连接,烧结体的致密度、硬度、强度均得到提高。铜磷预合金粉改善单质铁粉和铜粉的润湿性和结合力,并在晶界处生成脆性化合物,增加烧结体的脆性,提高了金刚石工具的锋利度,在金刚石工具行业中具有广阔的应用前景。Abstract: The carcass of diamond tools, which contained Cu-P pre-alloyed powder by hot pressing sintering process, was studied. The powder took through the instantaneous liquid brazing copper and iron based powder, improving the density, hardness and strength of the carcass. Cu-P pre-alloyed powder could improve the wettability and binding force of copper and iron powders, and form brittle phases at grain boundaries, thus increasing the brittleness of carcass and the sharpness of diamond tools. Cu-P pre-alloyed powder have broad prospects in the manufacturing of diamond tools.
