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， Ｂ４Ｃ（ＣＶＤ）颗粒与表面金属结合紧密
The surface of boron carbide particles was modified by chemical vapor deposition. X-ray diffraction confirmed the formation of a thin film of a mixture of chromium carbide and chromium boride on the surface of the boron carbide particles. Ni-W-Co-B4C (CVD) surface composites were prepared by electrodeposition. The results of wear test showed that the surface modification of B4C particles achieved good results. The B4C (CVD)
