| Abstract: |
| 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. |
