摘要

为提高纳米复合镀层中的纳米粒子含量

采用电泳-电沉积技术在铜基体上制备了Ni-Al2O3纳米复合镀层。首先用电泳沉积工艺在基体上均匀沉积出粒径为20nm的Al2O3涂层

然后在Al2O3涂层中电沉积金属镍

得到Al2O3体积分数高达55.6%的纳米复合镀层。对镀层表面形貌及镀层与基体的结合强度进行了测试与分析。结果表明

相比于纯镍镀层

采用电泳-电沉积法所制备纳米复合镀层的组织致密均匀

晶粒明显细化

镀层与基体的结合强度有所提高。

Abstract

Ni-Al2O3 nano-composite coating with high Al2O3 particles concentration was prepared by the electrophoretic-electrochemical deposition. Firstly

a uniform Al2O3 particle coating with an average size of 20 nm was deposited on a copper substrate by the electrophoretic method

then Ni was deposited into the substrate with Al2O3 particle coating by the electro-chemical method

finally the Ni-Al2O3 nano-composite coating with 55.6 Al2O3 particle in volumetric fraction were prepared successfully. Surface morphology and adhesive strength of the coating were examined. Compared with the pure Ni coating

the nano-composite coating exhibits more refine grain size with compact and uniform microstructure as well as higher adhesive strength.
