本文介绍了一种新的表面改性方法，通过电火花加工在工件上产生一个坚硬的表面和平面化的一层。当制造硬质碳化物的金属材料用作EDM中的电极时，在一定条件下可以制造硬质层。该过程开始于电极因放电的热量而磨损。然后，磨损的电极材料变成硬质碳化物。碳化物在工件上堆积成一层。通过两次或更多次放电形成的层具有层的性能、其粗糙度和硬度不够的问题。然后，为了改善层性能，研究了间隙宽度对层性能的影响。差距宽度的增加导致层性能的改善。
This paper describes a new method of surface modification by EDM to create a hard surface on a workpiece and planarization of a layer. When a metallic material that makes hard carbide is used as an electrode in EDM, a hard layer can be made under certain condition. The process begins with the electrode wear by heat of the electrical discharge. Then the worn electrode material becomes hard carbide. The carbide piles up on the workpiece and becomes a layer. The layer formed by two or more electrical discharges has a problem that performance of the layer, its roughness and hardness, is not enough. Then, in order to improve the layer performance, the influence that a gap width exerts on the layer performance was studied. The increase in the gap width resulted in improving the layer performance.
