采用电火花表面处理器,选用不同的电极材料,以W6Mo5Cr4V高速钢为基体材料,研究了电火花表面强化工艺对强化层性能的影响。结果表明,电极中的部分元素经强化后渗入到基体材料中,改善了强化层表面质量,强化层硬度、耐磨性显著提高。 By using EDM surface finder, different electrode materials were selected and W6Mo5Cr4V high speed steel was used as the matrix material to study the influence of EDM surface strengthening process on the performance of the strengthened layer. The results show that some elements of the electrode have been infiltrated into the matrix material after being strengthened, the surface quality of the reinforcing layer is improved, the hardness of the reinforcing layer is enhanced, and the abrasion resistance is remarkably improved.
