| 摘 要： | 采用TMPAC-AlCl3离子液体,在浸锌后的镁合金AZ31表面实施恒流电镀铝,采用电化学技术评估镀铝层的耐蚀性,并采用SEM/EDX等技术表征镀层。结果表明：在浸锌后的镁合金表面可获得表面光洁的银白色镀铝层。在不同的电流密度下,呈现出两种形貌不同的镀铝层;在较佳电流密度12.3mA/cm2时,镀铝层表面较致密;电镀时间越长,镀层越厚,镀铝层耐蚀性越好。

| Abstract: | Aluminum was electrodeposited with constant current on AZ31 magnesium alloy pretreated under optimized conditions from trimethyl-phenyl-ammonium chloride and anhydrous aluminum chloride (TMPAC-AlCl3) quaternary ammonium room temperature ionic liquids with benzene as a co-solvent. The corrosion resistance of the as-deposited Al layers was evaluated in 3.5% NaCl solution by the electrochemical technologies. The Al depositions were characterized by scanning electron microscopy equipped with energy dispersion X... |
