摘　　要：利用化学气相沉积技术对碳化硼颗粒表面进行改性，Ｘ－射线衍射证实在碳化硼颗粒表面形成碳化铬和硼化铬混合物的薄膜．利用电沉积技术制备了 Ｎｉ－Ｗ－Ｃｏ－Ｂ４Ｃ（ＣＶＤ）表面复合材料，油润滑条件下的磨损实验结果表明 Ｂ４Ｃ颗粒的表面改性取得了良好效果，Boron carbide has outstanding hardness, but it has not been researched and used. The coatings are deposed on boron carbide powders using Chemical vapor deposition. The structure of the film was studied by the X-fay diffraction. The character and the mechanism of friction and wear of Ni-W-Co-B4C composite electrodepsit were also studied, and the B4C powers before and after CVD treating were used. The results indicated the thin film was consisted of CrC and CrB after the CVD treating. In the condition of oil lubrication, the antiwear ability of Ni-W-Co-B4C (CVD) was improved, and the B4C (CVD) powders were well-adhered in the surface of metal coating.
