摘 要:为解决裸(SiC)P在应用中存在的不足,提出(SiC)P表面低成本化学改性的思路。采用简单的化学镀技术,改进氧化、亲水、敏化和活化的前处理工艺,对(SiC)P进行表面化学改性。确定了最佳的试验工艺,获得了镀层连续、无光滑(SiC)P裸露的较高质量的碳化硅复合粉体[简写为(Ni/SiC)P],通过SEM、EDS、XRD、TEM等测试,结果表明:改性后的(Ni/SiC)P较改性前的(SiC)P导电性有所提高,形貌、组成发生改变。同时分析了热处理对(Ni/SiC)P的影响,结果表明:随着温度的升高,(Ni/SiC)P表面改性层中的镍由非晶态转化为晶态。For solving shortage of naked (SiC)p in the application, the surface low cost chemistry modification on (SiC)p was expound. The simple electroless plating improved the pre-treatments technology including oxidation, geting close to water, sensitization and activation process. The continual, non-lubricous and high quality decoration of ( SiC ) p ( abbreviate as (Ni/SiC) p ) was obtained. Experiment results of SEM, EDS, XRD and TEM indicate that the electric functions of (Ni/SiC)p is much higher than those of unembellished (SiC)p, and morphology and structure of (Ni/SiC) p are changed. The effect of heat treatment on ( Ni/SiC ) p was also analyzed. The result expresses that along with the temperature, the non-crystalline state nickel in surface modified layer on (Ni/SiC)p becomes crystalline state nickel along with the going up of temperature.
