摘要: 在金刚石增强型硬质合金复合齿基体中添加不同量红磷,可降低复合齿烧结温度,实现低温活化烧结。研究表明:添加0.3%(wB) P的复合齿基体性能最好,采用化学镀Ni-P合金添加P和球磨添加0.1% P的方式,复合齿超硬部分的磨耗比和复合齿的抗冲击功优于单纯通过球磨添加0.3% P的超硬复合齿。为了实现金刚石增强型硬质合金复合齿的低温活化烧结,磷元素最优的添加方式是化学镀结合球磨的添加方式。

Abstract: Adding different qualities of phosphorus in the matrix of diamond enhanced carbide tungsten composite button can decrease its sinter temperature to keep low temperature activation sintering. Experimental results show the basis performance of adding 0.3 percent phosphorus is the best. Adopting the adding methods of combining adding nickel powder of the chemical coating nickel & phosphorus with ball-milling adding 0.1 percent phosphorus, the wear ratio of super hard layer and impact resistance of composite button are better than that of only ball-milling adding 0.3 percent phosphorus. It shows that the optimum adding method of phosphorus to implement low temperature activation sintering is adding the chemical coating nickel & phosphorus combined with adding phosphorus by ball-milling.
