摘　　要：金刚石柔性磨带镀点结合力的好坏,大多数并不是电镀工艺本身所造成的,而是基体镀前处理不当的结果,特别是基体的表面粗糙度和氧化膜的去除更与结合力密切相关。研究结果表明:不锈钢带基材表面经过粗化处理后,电镀试样卸下夹具没有镀点脱落现象,采用锉刀法测试,有部分镀点连同基材开裂,镀层结合力有很大提高;通过采用氢氟酸和硫酸混合酸进行酸洗浸蚀,除去了基材表面的氧化膜,实现镀层与基体的良好结合,采用锉刀法进行破坏性试验时,几乎所有镀点连同基体开裂。The bonding force of plated points of flexible diamond belts, which was not caused by plating process in most cases, but was caused by inappropriate pre-treatment of substrate material, in particular, the substrate surface roughness and the removal of the oxide film were closely related to the bonding force. The results showed that： after roughening treatment, plating sample did not appear shedding phenomenon of plated point, by using rasp method, some plated points were cracking together with the substrate, the binding force had great exaltation; by using a mixed acid of hydrofluoric acid and sulfuric acid, the oxide film of the surface of the substrate was removed, to achieve a good combination of the coating and the substrate, almost all plated points were cracking together with the matrix by destructive testing.
