| 摘 要： | 采用化学沉积方法获得了Ni-P纳米晶和非晶两种镀层,对镀态镀层进行低温去应力退火处理。分析了镀层成分和结构,研究了组织结构和退火工艺对镀层摩擦学性能的影响规律及其内在机制。结果表明:Ni-P纳米晶镀层的摩擦学性能明显优于同条件下(仅改变镀液中的络合剂)制备的非晶镀层,镀层磨损机制发生了变化;适当地去应力退火有助于进一步提高镀层的显微硬度,达到降磨减摩的效果。

| Abstract: | The two coatings of Ni-P amorphous and nanocrystalline structure were obtained by electroless plating. Moreover the as-deposited coatings were treated with stress-off annealing of low temperature. The composition and structure of the coatings were analyzed. Effects of anneal process and coating organize structure on tribological property of coating, as well as its inner mechanism, were studied. The result shows that the tribological property of Ni-P nanocrystalline coating is superior to that of amorphous one at the same condition(only changing the complex agent in the bath),and different wear mechanism between the two coatings is discovered too. The excellent friction and wear alleviation coating with higher micro-hardness is obtained owing to the proper anneal process. |
