摘　　要：本文研究了45、T10、3Cr2W8V钢预先镀铬,随后在粉末渗钒剂中渗钒的复合镀渗层的组织和性能。结果表明,铬钒复合镀渗层主要由VC、(V,Cr)C、(Cr,V)_(23)C6、Cr_(23)C6及Cr_7C_3组成。镀渗层与渗钒层相比,具有渗钒层的高硬度和高耐磨性,同时其耐蚀性、抗氧化性和抗热疲劳性均优于渗钒层。The structures and properties of compound plating diffusion layer of pre-plating chromium and post vanadizing in powder vanadizing agent on steels 45, T10 and 3Cr2W8V were studied. The result showed that chromium-vanadium compound plating diffusion layer is made up of VC, (V, Cr)C, (Cr, V)_(23)C_6, Cr_(23)C_6 and Cr_4C_3. The corrosion resistance, oxidation resistance and resistance to thermal fatigue of the compound plating diffusion layer are increased with the same level of hardness and wear resistance in comparision with vanadizing layer.
