摘要

在应用电铸技术制备Ni SiC纳米复合材料的工艺中

分析了当镀液pH值、温度以及搅拌速度一定时

镀液中纳米SiC颗粒悬浮量和阴极电流密度对Ni SiC复合电铸层中纳米SiC复合量和电铸速率的影响。用SEM对纳米复合电铸层的表面形貌和组织成分进行了分析

同时探讨了纳米复合电铸层中SiC颗粒复合量对其显微硬度的影响。结果表明

Ni SiC纳米复合电铸层表面光滑平整

显微组织均匀、致密

显微硬度较纯镍镀层有明显提高。

Abstract

Effects of the amoutnt of suspending nano-SiC particulate and cathode current density in the electrolyte on nano-SiC particulate amount and electrolyte rate in Ni-SiC compound electrolyte layer were analyzed at a given pH value

temperature and stirring speed for nano-Ni-SiC composite preparation. The surface morphology and structural constituent in the electrolyte layer were observed by SEM. Effects of nano-SiC particulate amount in compound electrolyte layer on the micro-hardness were approached. The results showed that the nano Ni-SiC plating layer possessed smooth and even surface

uniform and sound microstructure as well as higher micro-hardness than single Ni plating layer.
