研究了纯锌和锌镁铝合金（ZMA）在海洋环境（法国布雷斯特）中暴露6个月的腐蚀行为。采用红外光谱（FTIR）、X射线衍射（XRD）和X射线光电子能谱（XPS）分析了腐蚀产物的组成。观察到ZMA的耐腐蚀性改善。这种改善与Mg ~（2+）和Al ~（3+）引起的腐蚀活性淬灭和NaZn_4Cl（OH）（6）SO_4中心点6 H（2）O的增强有关。(C)2014爱思唯尔有限公司版权所有。
The corrosion behaviour of pure zinc and zinc-magnesium-aluminium alloy (ZMA) has been studied during 6 months of exposure in marine environment (Brest, France). The composition of corrosion products is analysed using infrared spectroscopy (FTIR), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). An improved corrosion resistance of ZMA is observed. This improvement is found to be connected to Mg2+ and Al3+ induced quenching of corrosion activity and to the enhancement of NaZn4 Cl(OH)(6)SO4 center dot 6H(2)O in the formed corrosion product.
