| 中文摘要: |
| 先采用电泳技术在铜基体表面沉积均匀、致密的金刚石微粒,再将已覆盖有金刚石微粒的基体放入电镀液中进行电沉积金属镍,获得了金刚石质量分数约为 48% 且分布均匀的 Ni-金刚石复合镀层。 与纯镍镀层进行磨损试验对比,发现制备的 Ni-金刚石复合镀层磨痕较浅,磨损量较小,其对磨件的磨损体积约为纯镍镀层对磨件的 17 倍,表明此两步沉积工艺制备的复合镀层具有良好的耐磨性能。 |
| 英文摘要: |
| The Ni-diamond composite coating was prepared by a two-step method. The uniform diamond particles was first electrophoretically deposited on a copper substrate. Nickel was then electrodeposited in the second step onto the substrate covered with the diamond particles. The two-step method enabled us to incorporate 48 % ( wt% ) of diamond particles into the nickel matrix. Compared with pure nickel coating under the wear experiment, the wear amount of the Ni-diamond composite coating was very small . The counter-grinding piece of the composite coating was 17 times than pure nickel coating. The result indicated that the composite coatings prepared by this method had a better anti-wear performance. |
