摘　　要：试验研究了钛催渗对W18Cr4V钢盐浴氮碳共渗的影响,分别就盐浴处理温度和时间等工艺参数对试样表面性能影响进行了研究。试验结果表明,钛催渗剂的多少对提高共渗层表面硬度具有显著作用,钛催渗可显著缩短盐浴处理时间,有效提高渗层厚度和硬度,能得到质量良好的渗层。Effect of the Ti catalytic on the salt bath nitrocarburizing of WlsCr4V steel was investigated, difference of the salt bath processing temperature and time as well as the dose of catalyst etc these crafts parameter to the effect of sample＇ s surface capability was studied. The results show that the quantity of Ti catalyst have remarkably effect to the enhance of suface hardness about nitrided layer, Ti catalytic can reduce the nitrocarburizing process remarkably, increase the depth of nitrided layer and enhance the surface hardenss effectively, improve the quality of nitrided laver.
