摘　　要：Sub-micron Co-Al_(2)O_(3)composite powders were synthesized by ultrasonic-assisted electroless plating process at room temperature with a one-step activating method pretreatment.The effect of process parameters on plating rate,Co content,and the uniformity of cobalt layer was analyzed by transmission electron microscopy(TEM).The results show that as the initial pH values of plating bath increase,the plating rate increases.The plating rate declines as the load increases when the load of powders is less than 12 g·L^(-1),but increases when the load is greater than 12 g·L^(-1).The relative Co content of the Co-Al_(2)O_(3) powder declines with the powder load increasing.
