一、引言金属表面渗硫是一种新的化学热处理工艺。国外的研究以法国为最早,苏联于1953～1955年首先由明斯克汽车制造厂的工程技术人员们提出了完整的资料。他们指出:金属表面由于渗硫的结果,得到了完全新的性质,使摩擦时不会产生“咬合”现象,即改善了零件的抗“咬合”能力,降低了摩擦系数,使能在不提高表面硬度的条件下增加耐磨性。因此,它为静多减摩材料及有色金属(如青铜)的代用开辟了广阔的前途。近年来,苏联、美、法、德、意等国有许多汽车制造厂、船舶机械厂、内燃机制造厂或工具制造厂都推行了 I. INTRODUCTION Sulphurizing metal surface is a new chemical heat treatment process. The earliest studies in foreign countries took France as the earliest, and from 1953 to 1955, the Soviet Union firstly put forward complete data from the engineers and technicians in Minsk Automobile Works. They point out that the metal surface has completely new properties due to the infiltration of sulfur so that there is no “bite” during friction, ie the part’s resistance to “bite” is reduced, its friction coefficient is reduced, Increased wear resistance under conditions of surface hardness. Therefore, it opens up a vast future for the static and anti-friction materials and non-ferrous metals (such as bronze) substitution. In recent years, the Soviet Union, the United States, France, Germany, Italy and other countries have many automobile factories, shipbuilding machinery plant, internal combustion engine manufacturing plant or tool manufacturers have implemented
