High-temperature oxidation resistance coating for silicon steel
-
摘要: 為了提高取向硅鋼板坯的抗高溫氧化性能,采用漿料法制備MgO-Cr2O3系的取向硅鋼用高溫抗氧化涂料.通過氧化增重、X射線衍射和電子掃描電鏡等測試方法,研究涂層保護下的取向硅鋼在不同溫度下的氧化增重規律以及1400℃下氧化產物截面形貌、元素分布特征.結果表明,該涂料對于取向硅鋼具有良好的高溫防護功能,且具有寬泛的抗氧化區域.Abstract: 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.
