| 中文摘要: |
| 金属一金刚石共沉积复合镀层，在不同应用领域（如提高耐磨性、自润滑性、切削性及弥散强化效果等）已得到广泛关注。详述了金刚石的嵌入对复合镀层的影响及其原因。试验发现，金刚石的嵌入恶化了复合镀层胎体的微观结构，使得胎体晶粒粗化、镀层和颗粒结合部出现间隙、镀层表面起伏不平并出现节瘤、沟谷及金刚石颗粒表面的过度包镶等现象。分析发现，以上现象是金刚石晶体内部金属包裹体的磁性，对运动的阳离子产生洛仑兹力作用，从而影响电沉积过程的结果。 |
| 英文摘要: |
| Electrodeposited diamond composite coatings have been widely studied for improving the hardness, wear resistance and self-lubrication. The detrimental impacts of diamond incorporation on the composites microstructure was reported. It is shown that the incorporation significantly worsens the microstructure , like coarsening the matrix grain , inducing gaps between matrix and diamonds, and promoting emergence of domed nodules, valleys and over-plating cases on the fluctuant matrix surface. All the deterioration facts are believed to arise from metallic inclusions trapped in diamond crystals during their synthetic process. |
