Aniline oligomer corrosion inhibiting coatings for magnesium alloys

镁及其合金因其高比强度和低密度等优异性能，被视为汽车、航空航天和消费电子行业的未来材料。总部位于加拿大的麦格纳是汽车行业最大的国际供应商之一，对开发汽车应用的镁合金有着浓厚的兴趣。在汽车制造中大量使用镁合金将在减轻重量的同时提高强度，从而大幅提高燃料效率。到目前为止，镁合金的耐腐蚀性很低，这阻碍了它们的广泛应用。研究表明，镁的腐蚀是不可避免的，但通过适当的防护涂层方案可以有效地控制腐蚀。最近的一项研究表明，一种聚苯胺(PANI)-祖母绿碱(EB)

Mg and its alloys are seen as materials of the future in the automotive, aerospace and consumer electronics industries due to their excellent properties such as high specific strength and low density. Canadian-based Magna is one of the largest international suppliers to the automotive industry, with a strong interest in developing Mg alloys for automotive applications. Making substantial use of Mg alloys in the construction of vehicles would improve strength while reducing weight, resulting in substantially increased fuel efficiencies. Until now, the very low corrosion resistance of Mg alloys has hindered their wide spread adaption. Research has shown that corrosion of Mg is unavoidable, but can be effectively controlled using an appropriate protective coating scheme. A very recent study has shown that a polyaniline (PANI)-emeraldine base (EB)
