| 摘 要： | 采用真空微蒸发镀覆工艺制备不同镀层厚度的镀铬金刚石，对铬镀层的物相组成和镀层厚度进行分析和表征。结果表明：改变镀覆温度和保温时间，可控制镀铬金刚石的镀层厚度。镀层的物相组成可通过镀覆质量增加来控制：质量增加10%的铬镀金刚石，其镀层只出现Cr3C2相；质量增加为20%时，有少量Cr7C3出现。从金刚石基体到铬镀层，镀层结构由低Cr比例的碳化物向高Cr比例的碳化物逐渐过渡，即为Cr3C2/Cr7C3；在金刚石尺寸确定的情况下，使用理论分析镀层厚度与镀覆质量增加的关系，如质量增加10%和65%的金刚石对应的铬镀层厚度分别为0.77μm和4.76μm，此结果与试验观察相吻合。

| Abstract: | Cr-coated diamonds with different coating weight gains were prepared by one pot reaction in a vacuum reactor, and the crystal phases and the thickness of the coatings were identified and analyzed. The results showed that the coating thickness varied with the temperatures and the holding time during coating. The crystal phases of the coating were related to the coating weight gains, which means that there appeared only Cr3C2 with 10% coating weight gain but Cr7C3 with 20% coating weight gain. It is also found that from the diamond surface to the Cr coating, the crystal phases are gradually transited from Cr3C2 to Cr7C3. For diamond with a certain particle size, there was a certain correspondence between the coating thickness and the coating weight gains. For example, when the coating thickness of the Cr-coated diamonds with 10% weight gains was 0.77 μm and that of diamonds with 65% coating was 4.76 μm, which was consistent with the SEM results. |
