Technology of ultrasonic-electroless plating Ni-P-SiC nanocomposite coating

采用超声波-化学镀的方法,在45钢基体表面制备Ni-P-SiC纳米复合镀层。利用正交试验法对制备Ni-P-SiC纳米复合镀层的工艺参数进行优化,并确定SiC纳米粒子的加入量、超声波功率、复合镀液的温度以及pH值。最后,利用扫描电镜(SEM)和原子力显微镜(AFM)对复合镀层的显微组织形貌进行观察和分析。

Ni-P-SiC nanocomposite coatings were prepared by ultrasonic-electroless plating on surface of 45 steel substrate.Through orthogonal experiment,the technology parameters of plating Ni-P-SiC nanocomposite coatings were optimized and the best addition amount of SiC nanoparticles,ultrasonic power,temperature of plating liquid and pH value were determined.The microstructure of the coatings was observed and analysed by scanning electron microscopy（SEM） and atomic force microscopy（AFM）.
