Ni on the AZ91D magnesium alloy, containing sulfate nickel, was given in this paper. The nucleation mechanism of Ni-P deposits on the AZ91D magnesium alloy was studied by using XRD and SEM.The electroless Ni-P deposits were preferentially nucleated on the β (Mg17Al12) phase and extended to the primary and eutectic α phases of the AZ91D magnesium alloy. 关键词:Electroless deposition; AZ91D magnesium......
