摘 要: 用化學(xué)鍍法在活性鋁粉表面包覆純鎳層制備Ni-Al復(fù)合粉末。結(jié)果表明，控制溫度為86~89℃、 pH= 12.5~13.2 、硫酸鎳加入量為35.0~45.0 g/ L、還原劑加入量為75~95 mL/ L時(shí)可獲得鍍覆質(zhì)量良好的粉末，且鎳呈結(jié)晶態(tài)析出。此外還討論了這些工藝參數(shù)對鍍覆質(zhì)量的影響。

Abstract:The composite powders were produced by electroless pure-nickel plating on the surface of activated aluminium powders. The experimental results showed that the well-qualified composite powders can be made by controlling technological parameters and nickel appears in crystal state. The influence of the technological parameters on the coating quality was also given.
