摘　　要：对W9Mo3Cr4V钢进行气体软氮化处理,研究氮化处理对钢组织及性能的影响。结果表明:采用甲酰胺为渗剂进行气体软氮化可得到约50μm的致密渗层,可有效提高W9Mo3Cr4V钢的硬度和耐磨性。经软氮化后,钢的表面硬度达到1150 HV0.1,而磨损速率约为3.9 mg/h,为未经软氮化的1/5。The effects of nitrocarburizing on microstmcture and properties of W9Mo3Cr4V steel were researched. The results show that the steel Can get a dense nitrocarburizing layer with about 50 μm by gas nitrocarburizing using formamide as impregnant. The nitrocarburizing layer can effectively improve hardness and wear resistance of W9Mo3Cr4V steel. After nitrocarbarizing, surface hardness increases to 1150HV0.1 and wear loss rate is about 3.9 mg/h, which is one fifth of those without nitrooarburizing.
