Aniline oligomer corrosion inhibiting coatings for magnesium alloys

由于具有高比强度和低密度等优异性能，Mg及其合金被视为汽车、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，对开发汽车用镁合金有着浓厚的兴趣。在车辆结构中大量使用镁合金可以在减轻重量的同时提高强度，从而大大提高燃油效率。迄今为止，镁合金的耐蚀性很低，阻碍了其广泛应用。研究表明，镁的腐蚀是不可避免的，但可以通过适当的保护涂层方案有效地控制。最近的一项研究表明，聚苯胺(PANI)-绿宝石碱（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)
