热轧钢材表面氧化铁皮微观结构表征技术综述

热轧钢材氧化铁皮控制不当会引起表面缺陷，为了提高热轧钢材的表面质量，需要对其氧化产物结构和状态进行系统的分析检测，包括了解氧化铁皮的种类和结构、氧化铁皮的表面及断面形貌、氧化铁皮或氧化铁皮与钢基体界面处的元素分布等。由于目前表面分析技术种类多，且新技术不断得到应用，本文按照钢材氧化铁皮研究的表征步骤归纳了各种技术的特点和应用情况，可为钢材高温氧化理论研究和生产现场工艺优化提供帮助。

Review of characterization techniques on oxide scale microstructure of hot rolled steels

The surface defects of hot rolled steels can be caused by improper control of oxide scale.Systematic analysis and detection of structure and status of oxide scale is an important way to improve the surface quality of steels.The characterization techniques focus on species,surface and cross- section morphology and the elements distribution of oxide/matrix interface of oxide scale.The various new type of characterization techniques have been widely applied in the studies of high temperature oxidation behavior.The paper summarizes the specialty and application of characterization techniques following the general steps,which provide a reference for the theory study of high temperature oxidation behavior and production process optimization.
