摘要
利用简单的化学镀方法,实现了SiC颗粒的表面化学修饰。通过对酸性、碱性修饰液的比较研究,证实在相同条件下,碱性镀液的修饰效果较好;采用SEM,TEM,EDS和XRD,对修饰前、后的SiC颗粒的物相、晶形、成分等进行了研究,初步表征了Ni/SiC颗粒复合粒子的微结构;并考察了热处理对修饰后SiC颗粒的影响。
The surface of silicon carbide particles was decorated by electroless plating. It has been proved that the plating in basic bath has better decorating silicon carbide than that of plating in acidic bath under the same condition. The surface of silicon carbide particles before and after decoration, including phase, crystalline, nickel and its compounds, and feature of decorated coating, is investigated. The microstructures of Ni/SiCP is characterized preliminarily by means of SEM, TEM, EDS and XRD. In addition, the heat treatment effect on silicon carbide particles after decoration is studied.
