通过选择合适的化学镀铜工艺在金刚石表面镀覆一层金属铜，该方法可以调节镀层厚度，可一次镀也可多次镀。通过ＸＲＤ、ＳＥＭ、ＥＰＭＡ等分析手段对镀铜金刚石进行了分析，结果表明：一次镀镀层形貌松散，多次镀镀层形貌紧密，镀层铜呈晶态，并含有少量的氧和铁等杂质。磨削结果表明：镀铜金刚石砂轮其耐磨性明显优于普通金刚石砂轮，多次镀铜铜含量较高的金刚石更适合于制造树脂砂轮 By selecting a suitable electroless copper plating process, a layer of copper metal is plated on the surface of the diamond. The method can adjust the thickness of the coating and can be plated once or multiple times. The results show that the morphology of the first plating is loose, the morphology of multiple plating is close, the copper of the coating is in a crystalline state, and contains a small amount of impurities such as oxygen and iron . The grinding results show that the wear resistance of copper-plated diamond wheel is obviously better than that of ordinary diamond wheel, and the diamond with higher copper content is more suitable for making resin wheel
