前言电火花熔渗强化是通过电火花放电,在被处理表面形成一层高硬度、高耐磨、抗腐蚀的强化层,是一种新型的表面强化处理。通过选择不同的电极材料,可达到各种所要求的性能。电火花熔渗强化,在本世纪四十年代,国外已有报导。我国在五十年代初也有应用,但由于设备不完善,强化机理不清楚,强化效果不稳定等原因,而未能得到广泛应用。这一强化手段直到近几年才被人们所重视,但对熔渗强化的工艺规律,相组织的分
INTRODUCTION EDM strengthening is a new type of surface strengthening treatment by EDM, forming a layer of high hardness, high wear-resistant and corrosion-resistant strengthening layer on the treated surface. By choosing a different electrode material, you can achieve a variety of performance requirements. EDM infiltration enhancement in the forties of this century, foreign reports have been. Our country also had the application in the early 1950s, but because of the equipment imperfect, the strengthening mechanism is not clear, the enhancement effect is unstable and so on, but has not obtained the widespread application. This method of reinforcement has not been taken seriously until recent years, but the infiltration of the strengthening of the law of technology, the organization of the points
