2Crl3钢膏剂法B-V共渗中渗层的形成

The Formation of Permeating Layer During B-VCo-permeatimg of 2Cr13 Streel With Paste

通过试验的方法，研究了２Ｃｒｌ３钢膏剂法Ｂ一Ｖ共渗中渗层相的特征和形成，以及共渗温度、保温时间等工艺参数对渗层的影响．试验结果表明，在工艺参数和渗剂配方的最佳配合下，渗层深度可达６０～８０ｕｍ，渗层硬度可达ＨＶ１８００－２２００．该成果对复合渗金属共渗机理的研究有一定的参考意义。

ln this paper, the characteristics and formation of the B - V co - permeatinglayer of 2Crl 3 steel is studied , as well as the influence of temaperature and holding tima on it.The results show that the layer can be 60 ～ 80um' s thick and its hardnes can be HV 1 800 ～ 2 200 with the best coordination of technical parameters and permeating agentoomposition during B - V co - permeating process. The accozaplishment provides valuablereference for the study of co - permeating theory.
