High-temperature oxidation resistance coating for silicon steel

An anti-oxidation coating,mainly composed of MgO and Cr2O3,was prepared by a mixing method.XRD and SEM were used to study the difference of mass increment,oxidative products and element distribution between samples with and without coatings at 1400℃.The results show that the coatings are environmental-friendly and cost effective and also have good effect on grain-oriented silicon steel,with a wide range of anti-oxidation applications.
