| 目的 制备具有优良自润滑性能的 Ni-PTFE 复合镀层,同时探究其摩擦学性能。 方法 首先在铜基体表面电泳沉积一层 PTFE 膜,再将覆有 PTFE 膜的基体放入光亮镀镍溶液中进行电沉积(电泳-电沉积法),用 SEM 附带的能谱仪检测复合镀层的 PTFE 复合量,同时在自制的销盘摩擦磨损实验机上进行相关的摩擦学实验,以评价其摩擦学性能。 结果 用电泳-电沉积法制备出了含量(以体积分数计) 达63. 4% 的 Ni-PTFE 复合镀层。 在干摩擦条件下,PTFE 微粒的加入可以降低复合镀层的摩擦系数(最低至0. 067)。 结论 高 PTFE 复合量的复合镀层具有良好的耐磨性能。 |

| Objective To prepare Ni-PTFE composite coatings with excellent self-lubricating property, and to explore its tribological performance. Methods First, a layer of PTFE membrane was deposited on the surface of the copper matrix by electrophoretic deposition, and then the matrix with a layer of PTFE membrane was put into the bright nickel plating solution for electrodeposition (electrophoresis-electrodeposition method). SEM with EDS was used to detect the PTFE contents of the composite coating. At the same time, related tribological experiments were conducted on a self-developed pin disk friction tester, so as to evaluate its tribological performance. Results Using the electrophoresis-electrodeposition method, composite coatings with 63. 4% Ni-PTFE were prepared. The addition of PTFE particles could decrease the friction coefficient of the composite coating (minimum 0. 067) under dry friction condition. Conclusion The composite coating with high content of PTFE had good wear resistance. |
