| 中文摘要: |
| 为了提高直线往复运动平面电刷镀复合镀层分布的均匀性，采用电刷镀方法制备了Ni-PTFE复合镀层，使用能谱仪、扫描电镜和显微硬度计分别研究了复合镀层的元素组成、表面形貌和显微硬度分布，并推导出基底各处与阳极接触时间分布的计算公式。结果表明：镀层分布取决于基底各处与阳极接触时间分布；接触时间是阳极长度与基底长度的函数。增加基底长度或选择较短的阳极，可提高接触时间分布的均匀性。接触时间分布均匀性的提高是以牺牲镀层生产率为代价的。 |
| 英文摘要: |
| To improve the uniformity of the plate Ni-PTFE composite coating prepared by brush electroplating with straight-line reciprocating movement , the deposition behavior, microstructure and micro-hardness at various locations were measured and analyzed using EDAX, SEM and micro-hardness tester. The equation of the contact time between the cathode and the anode was deduced. The results show that the coating distribution depends on the contact time distribution. The contact time is a function of the anode length and the substrate length. The plate coating with high contact time uniformity can be obtained by selecting short anode or long substrate. However, the higher contact time uniformity is obtained at the cost of the coating productivity. |
