研究了加有CS_2的气氛中的硫氮共渗。在作为载体的丙烷裂化气里,添加50％的NH_3和0.006％的CS_2,把S45C试样于843°K(绝对温度)在上述气氛中处理10.8KS(千秒),X线衍射证实,表面生成物分别为Fe_(1-x)S、FeS、Fe_3和Fe_4N;在被处理试样的横截面组织中观察到化合物层;渗层的硬度由表及里逐渐提高,并在化合物内层达到极大值。从这些结果上看,采用加有CS_2的气氛,进行钢的硫氮共渗是可能的。
Sulfuritriding in a CS 2 -containing atmosphere was investigated. In a propane cracked gas as carrier, 50% NH 3 and 0.006% CS 2 were added, and the S45C specimen was treated at 843 ° K (absolute temperature) for 10.8KS (kilo seconds) in the above atmosphere. X-ray diffraction confirmed that the surface The products were Fe_ (1-x) S, FeS, Fe_3 and Fe_4N respectively. The compound layer was observed in the cross-sectional structure of the treated sample. The hardness of the layer increased gradually from the inside to the inside of the compound maximum. From these results, it is possible to carry out the sulfuritriding of steel by using the atmosphere added with CS_2.
