    摘要:

    鎂合金表面鍍鎳被廣泛運(yùn)用于鎂合金工件防腐,而鍍層的起泡和脫落嚴(yán)重影響工件的使用壽命。本文以ZK60鎂合金為對(duì)象,研究了不同工件基底表面質(zhì)量對(duì)鍍鎳層的影響機(jī)制。研究表明：基底表面存在的劃痕和點(diǎn)蝕坑會(huì)顯著降低鍍鎳層質(zhì)量,引起鍍層的起泡和脫落?；妆砻娴膭澓蹠?huì)被保留到鍍鎳層中,引發(fā)鍍層變薄,應(yīng)力集中等問題,增加鍍層開裂的幾率。點(diǎn)蝕坑中的雜質(zhì)與鎂基底有不同的電化學(xué)特性,會(huì)導(dǎo)致鍍層減薄和結(jié)合不牢。因此,提高鎂合金工件基底表面光潔度、清除基底表面點(diǎn)蝕坑是提高鎂合金鍍鎳層性能的必要措施。

    Abstract:

    Nickel plating on the surface of magnesium alloy is widely used in the anti-corrosion of magnesium alloy workpiece, but blistering and peeling from nickel plating will seriously affect service life of the workpiece. In this paper, effects of the different substrate surfaces on nickel plating properties of ZK60 magnesium alloy were studied. The results showed that the surface scratch and corrosive pitting significantly reduced the coating quality and caused blistering and peeling from nickel plating. The surface scratch of the substrate was retained under the nickel plating layer, which made the coating thinner, and caused stress concentration in the coating, and increased the probability of coating cracking. Differences in electrochemical properties between impurities in pitting pits and magnesium substrate led to thinning of the coating and weakened the adhesion of the coating. Therefore, good substrate surface finish and no substrate surface corrosive pitting are the guarantee of high quality nickel plating of magnesium alloy workpiece.
