摘要
将冷轧取向硅钢样品在不同退火条件下进行退火,并结合现有的检测手段(FTIR、GD-OES)和Raman光谱分别对最终生成的氧化层进行综合检测分析。研究结果表明,Raman光谱能快速准确地检测出氧化层成分,样品在低氧化性气氛条件(pH2O/pH2=0.288)下,于850℃退火3min后所生成的氧化层成分为SiO_2-FeSiO_3组织;并且随着反应气氛氧化性的提高(pH_2O/pH_2增加),氧化层中FeSiO_3的含量也随之增多。
The cold-rolled grain oriented silicon steel samples were decarburization annealed under different annealing conditions, and Raman spectra was applied to comprehensively analyze the oxide layers combined with existing detection methods （ Fourier transform infrared spectroscopy, Glow discharge optical emission spectroscopy）. The results showed that Raman spectra could detect the composition of oxide layer quickly and accurately, and the oxide layer was found to be SiO2-FeSiO3 in the sample which was annealed at 850℃ for 3 min in low oxidizing atmosphere （pH2O/pH2 = 0. 288）; In addition, the FeSiO3 content in oxide layer would increase as raising the oxidizing atmosphere.
