| 中文摘要 | The pretreatment processes and initial deposition mechanism of electroless nickel plating on AZ91D magnesium alloy were investigated by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX). The results showed that alkaline cleaning could remove the greases and oils from the substrate surface. Acid etching could wipe off the metal chippings and oxides. The hydrofluoric acid activating process which could improve the adhesion of coating to substrate played a key role in the subsequent process of electroless nickel plating. The nickel coating was deposited preferentially on the primary alpha phase and then spread to the eutectic alpha phase and beta phase. The nickel initially nucleated on the primary alpha phase by a replacement reaction, then grew depending on the autocatalysis function of nickel. The coating on the beta phase displayed better adhesion than that on the alpha phase due to the nails fixing effect |
