- 摘要:
- 采用复合共沉积方法,研制了基于紫铜基体的 Ni-PTFE (镍 - 聚四氟乙烯)复合镀层。在镀液中 PTFE 的分散性研究的基础上,考虑 PTFE 悬浮量对复合镀层的影响,开展了对单一 Ni 镀层以及 Ni-PTFE 复合镀层摩擦学性能研究。研究结果表明:相对 Ni 镀层而言, Ni-PTFE 复合镀层具有很好的减摩效果。 Ni 镀层的摩擦系数为 0.7 , Ni-PTFE 复合镀层的摩擦系数为 0.22 ,仅为镍镀层的 32% 左右;此外, Ni-PTFE 复合镀层的磨损小,耐磨性能优异。其中,添加( 20 mL/L ) PTFE 的复合镀层综合性能最优。
- Abstract:
- : A composite co-deposition method was used to prepare a Ni-PTFE composite coating on the copper substrate. Based on the research on the dispersion of PTFE in the plating solution , the influence of PTFE suspension on the composite coating is considered. The tribological properties of single Ni coating and Ni-PTFE composite coating are studied. The results of the study are that the Ni-PTFE composite coating on the surface has a good anti-friction effect compared with the Ni coating. The coefficient of friction of the Ni coating is 0.7 , and the coefficient of friction of the Ni/PTFE composite coating is 0.22 , which is only about 32% of that of the pure nickel coating. At the same time , the wear is lighter , showing excellent wear resistance , the composite coating with ( 20 mL/L ) PTFE has the best overall performance.
