摘要: 

研究了密闭容器中2205双相不锈钢于1050 ℃氧化时表面氧化膜的初始形成过程。应用金相显微镜、SEM、Raman光谱仪以及辉光放电光谱仪等表征手段,分析了2205双相不锈钢表层氧化物的形貌、结构和组成。结果表明：氧化初始阶段 (小于3 min),铁素体相和奥氏体相表面的氧化程度及氧化物类型明显不同,铁素体相表面主要形成富铬氧化物,而奥氏体相表面主要形成铁氧化物,氧化初始阶段铁素体相抗氧化能力优于奥氏体相。随着氧化时间的延长 (大于5 min),两相表面富铬和富铁氧化物发生了明显变化,即铁素体相表面的铁氧化物增多,氧化速率加快;而奥氏体相表面的富铬氧化物增加,此时奥氏体相的氧化速率逐渐平缓。氧化过程中,Cr经历了从次表层向表层扩散过程,最终在表层形成了一定厚度的富铬氧化物。密闭环境中,2205双相不锈钢表面极易形成颗粒状氮/氧化物,且在铁素体相表面优先形成;氧化达到一定时间后,奥氏体相表面也开始析出该类型化合物,随着氧化时间的延长其数量越来越多,直至分布于整个试样表面。

Abstract：

The initial formation process of oxide scale on 2205 duplex stainless steel at 1050 ℃ was studied in static atmospheric air within a closed container of 304 type stainless steel. The morphology, structure and composition of the formed oxide scale was analyzed by means of metallographic microscope, scanning electron microscope, Raman spectroscopy and glow discharge spectrometer. Results show that at the beginning of oxidation (less than 3 min), the oxidation degree and type of oxides formed on ferrite and austenite phases are obviously different, namely, which on the surface of ferrite phase composed mainly of Cr-rich oxides, while on the austenite phase composed mainly Fe-rich oxides. The oxidation resistance of ferrite phase seems better than that of the austenite phase. With the increase of the oxidation time (more than 5 min), the oxidation rate of the ferrite phase increased while Fe-rich oxides scale thickened on their surface. On the contrary, the Cr-rich oxide scale grew thicker on austenite phases, while their oxidation rate became gradually gentle. With the progress of oxidation, Cr diffused and migrated from sub-surface to the surface, leading to the formation of Cr-rich oxide on the whole surface of the duplex stainless steel. In this confined environment, the surface of the duplex stainless steel is easy to form granular compounds containing nitrogen and oxygen preferably on the ferrite phase, and afterwards these compounds also formed on the austenite. The number of the granular compounds is increasing with oxidation time and finally would cover entirely the steel sample.
Key words： duplex stainless steel    high temperature oxidation    microstructure    oxidation mechanism
