本文研究了钢在添加 CS_2的气氛中进行的气体硫氮共渗法。把50％NH_3和0.006％CS_2加入到由丙烷裂解的载气中,45钢试样在这种气氛中,在570℃处理3小时。X 射线衍射测定表面的产物分别为Fe_(1-x)S,FeS,Fe_3N 和 Fe_4N。表面试样的横截面显微结构观察到化合物层。硬度从表面向内部逐渐增加,达到最大值后逐渐降低。由此证明,在加入 CS_2的气氛中进行钢的气体硫氮共渗是可行的。
In this paper, the gas sulfur-nitrogen gas permeation method in the atmosphere of adding CS_2 was studied. 50% NH 3 and 0.006% CS 2 were added to the carrier gas cracked with propane and the 45 steel sample was treated in this atmosphere at 570 ° C for 3 hours. X-ray diffraction measurement of the surface of the product were Fe_ (1-x) S, FeS, Fe_3N and Fe_4N. Cross-sectional microstructure of the surface sample A compound layer was observed. The hardness gradually increases from the surface to the inside, and gradually decreases after reaching the maximum value. This proves that it is feasible to conduct gas sulfur nitriding in the atmosphere with CS_2 addition.
