摘要: 镁合金微弧氧化（MAO）预处理后，无需碱洗酸洗活化等传统预处理直接在硫酸镍溶液中化学镀镍。表征了镀镍层的显微结构与成分，研究了MAO预处理对镀层厚度、硬度、导电性及耐蚀性的影响。结果表明：含有Ni，P两种元素的镀层由均匀分布的胞状颗粒组成。 MAO预处理显著影响镀层的厚度与导电性；当MAO薄膜从3 μm增厚至7 μm时，镀层的厚度快速增大而方块电阻迅速下降。极化曲线测试表明，当MAO薄膜厚15 μm时化学镀镍镁合金的腐蚀电位最高，腐蚀电流最小。48 h盐雾实验表明，MAO预处理化学镀镍镁合金的耐蚀性显著优于传统预处理化学镀镍镁合金。

Abstract：Magnesium alloys after microarc oxidation (MAO) pretreatment were directly electroless Ni plated by using NiSO₄ solution, meanwhile, any traditional pretreatment, including alkaline washing, acid washing and activation, etc., was used. The microstructure and composition of nickel layer were characterized. The effect of MAO pretreatment on the thickness, hardness, electrical conductivity and corrosion resistance of nickel layer were investigated. The results indicate that the layer which contains Ni and P is composed of cellular particles. MAO pretreatmely affects the thickness and electrical conductivity of nickel layer significantly. The thickness of nickel layer fastly increases but the sheet resistance of the layer rapidly decreases when the thickness of MAO film increases from 3 to 7 μm. Furthermore, the results of polarization curve test reveal that when the thickness of MAO film is 15 $\mu$m, the corrosion potential of the obtained electroless nickel plated magnesium alloy is the highest, and the corrosion current is the lowest. The results of 48 h salt spray test show that the corrosion resistance of electroless nickel plated magnesium alloy with MAO pretreatment is much higher than that of electroless nickel plated magnesium alloy with traditional pretreatment and magnesium alloy substrate.

Key words： magnesium alloy microarc oxidation electroless nickel plating pretreatment corrosion resistance
