| 摘要: |
| 机械装备工业中的许多运动部件如，齿轮、曲轴，液压油缸、活塞环、模具等表面在使用过程中不可避免会遇到摩擦、磨损、润滑与腐蚀问题。利用电沉积表面工程技术可以有效地降低材料的磨损与腐蚀，延长工件使用寿命。本文就课题组在纳米晶以及新型梯度合金镀技术对材料表面润滑、抗磨与耐蚀性能方面的研究作一介绍，旨在促进电沉积表面工程技术在装备零部件表面强化和工艺设计中的应用与发展。 |

| Abstract: |
| friction, wear and corrosion process inevitably occurred during the operation of motion parts and mechanical components, such as gears, bearing, shafts, cylinders, piston ring and moulds under many working conditions. Optimum application of electrodeposition surface engineering techniques can considerably decrease the wear and corrosion loss, and hence effectively prolong the serving life of components. The research work on nanocrystalline and functionally graded alloy deposits in our group were briefly introduced in this paper, which aimed at promoting the application and development of novel electrodeposition methods in the manufacturing engineering. |
