对取向硅钢在不同气氛下的高温退火工艺进行实验室模拟,利用X射线衍射仪(XRD)分析了硅钢退火至900℃和1170℃时的样品表面氧化层和底层的物相组成,采用场发射扫描电镜(SEM)观察了样品表面氧化层和底层在截面方向上的微观形貌特征,并计算了高温退火一次升温阶段氧化反应的吉布斯自由能以及900℃时退火气氛的氧分压。结果表明:当退火气氛的露点温度保持一定时,较高的氢气含量有利于生成完整连续的底层;当退火气氛的水氢分压比保持一定时,在露点温度与氢气含量两者较低的条件下,底层附着性不佳易脱落,较高条件下,底层中夹杂着较多的铁单质;当氧化层中无FeO时,底层完整连续但易脱落,当FeO层较薄时,底层下方存在部分未反应的SiO2,当FeO层较厚时,底层不完整连续且有分层。 The high temperature annealing process of grain-oriented silicon steel in different atmospheres was simulated in the laboratory.
