摘要:
硬度低和耐磨性较差制约了铜在冶金设备领域的应用.为了提高铜金属表面硬度和耐磨性,采用镀镍料浆包渗铬技术对铜表面进行渗铬.制备渗铬层,并对其微观组织、扩散特性及显微硬度和耐磨性进行了研究.结果表明:铜表面经镀镍渗铬处理后,在镍层表面获得50μm的渗铬层,渗层组织为镍铬固溶体相;渗层硬度由外层的345 HV逐渐降低到镍镀层的120 HV和铜基体的70 HV,渗层显微硬度随铬含量的降低而降低.渗铬处理将铜和镍的摩擦系数由原来的0.8和0.6降低到0.45.
Abstract:
Low hardness and poor wear resistance restrict the application of copper in the field of metallurgical equipment. In order to improve the surface hardness and wear resistance of copper metal, the nickel-plated slurry clad chromizing technology is used to chromize the copper surface. The chromium-infiltrated layer was prepared, and its microstructure, diffusion characteristics, microhardness and wear resistance were studied. The results show that after nickel plating and chromium plating on the copper surface, a 50μm chromium permeated layer is obtained on the surface of the nickel layer, and the structure of the permeable layer is a nickel-chromium solid solution phase. The hardness of the permeable layer gradually decreased from 345 HV in the outer layer to 120 HV in the nickel coating and 70 HV in the copper matrix, and the microhardness of the permeable layer decreased with the decrease of chromium content. Chromium permeation reduces the coefficient of friction of copper and nickel from 0.8 and 0.6 to 0.45.
