【摘要】 采用扫描电镜、原子力显微镜研究了铬酸镁半无机绝缘涂层的微观结构。结果表明,涂层厚度为数微米,涂层中的有机树脂乳液颗粒均匀分布在无机涂层的表面,从而保证了涂层具有良好的冲片性能。采用极化曲线研究了涂层的耐蚀性能,发现铬酸镁与铬酸锌绝缘涂层的耐蚀性能相当。
【Abstract】 In this paper,the microstructure and anti-corrosion property of magnesium chromate coating on non-oriented silicon steel were studied.The microstructure was observed by SEM and AFM.The anti-corrosion properties were evaluated by polarization curves.The results show that the thickness of coating is several microns and the polymer particles were scattered on the surface of inorganic coating,which is the guarantee for lamination property.The corrosion resistance of the magnesium chromate film was e...
