摘　　要：采用超声-电沉积Ni-SiC纳米镀层方法,在A3钢表面制得Ni-SiC纳米镀层。利用CA预测模型研究超声-电沉积Ni-SiC纳米镀层的显微组织结构。结果表明,在Ni-SiC纳米镀层中存在Ni和SiC相。随着超声波功率的增加,Ni-SiC纳米镀层的显微组织更加致密、光滑。CA预测说明,在NC-1,NC-2和NC-3镀层中,镍晶粒的平均粒径分别为188.2,135.7和70.5nm,SiC粒子的平均粒径分别为105.4,80.9和36.2nm。CA预测模型的预测结果与实测结果相差不大,最大误差为5.0%。Ni-SiC nanocomposite coatings were prepared on steel A3by ultrasonic-electrodeposition method.The microstructures of Ni-SiC nanocomposite coatings were investigated using CA model.The results illuminated that there was Ni and SiC phase in Ni-SiC nanocomposite coatings.And the coating had a compact and fine microstructure with increasing of the ultrasonic power.It was found that nickel grains in NC-1,NC-2and NC-3coatings were 188.2,135.7and 70.5nm,respectively,and that of SiC particles were 105.4,80.9and 36.2nm,respectively.CA model showed that there was little difference between the predicted and measured results,and the maximum relative error was 5.0%.
