【摘要】：研究了退火过程的露点温度对C-Si-Mn体系高强钢表面选择性氧化行为的影响规律。退火实验在带有露点控制器的热浸镀工艺模拟器上进行,采用扫描电镜和能谱仪表征退火后的样品表面特征,使用辉光放电光谱仪表征合金元素的深度分布。结果表明,随着硅含量从0.2 mass%增加到1.2 mass%,大量复合氧化物覆盖了样品外表面。随着退火过程露点温度从-50℃增加到-30℃,Mn元素倾向于向外表面富集。进一步将露点温度从-30℃提高到-10℃后,样品表面富集的Mn和Si反而减少。
[Abstract]:The effect of dew point temperature during annealing on the surface selective oxidation behavior of high strength steel C-Si-Mn was studied. The annealing experiment was carried out on a hot dip plating simulator with dew point controller. SEM and EDS were used to characterize the surface characteristics of annealed samples, and glow discharge spectrometers were used to characterize the depth distribution of alloying elements. The results show that with the increase of silicon content from 0.2 mass% to 1.2 mass%, a large number of composite oxides cover the outer surface of the sample. With the increase of dew point temperature from-50 鈩，
