摘要
研究了电刷镀多层复合镀层工艺的装置与技术条件 ,对电刷镀镀笔进行必要的改进 ,探索了利用改进的电刷镀技术制备性能优良的多层Ni Cr2 O3 、Ni SiC等复合镀层在工艺上的可行性 同时 ,还研究了多层复合镀层的强度、组织及显微硬度等性能 结果表明 ,多层复合镀层具有良好的结合强度 ,细小的结晶晶粒和较高的显微硬度 本研究的成果可用于修复磨损的机械零件和对零部件进行表面强化 。
The installation and technical process of electric brushing coating for multilayer composite coating are tested and studied. The coating pen is modified. The feasibility of acquiring multilayer composite coating of Ni Cr 2O 3 and Ni SiC are also studied. In addition, the strength, microstructure and microhardness of multilayer composites are examined. The results show that multilayer composite coatings have good cohesive strength and fine crystal grains. The research results can be used in repairing and surface strengthening the worn machine parts.
