纳米金刚石稳定水分散体系在复合电镀铬中的应用

Study on the Nano Diamond Stable Water Disperse System and Applying in Composite Chromium Plating

研究纳米金刚石水基稳定分散体系的组成及分散操作工艺.以低泡沫磺酸基阴离子表面活性剂作分散活化剂,比较了各种机械搅拌方式对体系稳定性的影响,并以复合镀铬作应用试验.测定了纳米金刚石复合镀铬的镀层沉积速率,镀层硬度,耐磨性等参数,由SEM观察镀层晶态结构图像.列举了试验结果、测试数据及复合镀铬的工艺条件,并对实验结果及机理进行了分析探讨.

The nano diamond stable water disperse system was studied. The low-bublles sulfonic anion sufcace active agent had been choosed out for this system. The affect of different physics agitation toothed on the water separate system stablity were conpared. The nano diamond stable water separate system had been applied to the composite chromium electroplating on this tests. The depositing speed, hardnees and wearing capacity of plating layer were tested. And the metallography structure of plating layer was charasterized by SEM. The test results and reaction princeple were discussed.
