摘要:

采用电化学测试、扫描Kelvin探针 (SKP)、原子力显微镜 (AFM) 和浸泡实验等手段研究了两种热处理条件下含3%Cr (质量分数) 的低碳钢在含Cl^-环境中的腐蚀行为与机理，利用微区电化学等手段建立了显微组织与耐蚀性的相关性。结果表明：含3%Cr钢退火后得到单一铁素体组织，正火后得到铁素体+贝氏体组织。两种组织的差异是造成初期腐蚀形貌差异的根本原因，正火组织由于不同相间的电偶效应导致其耐蚀性较退火组织差。

关键词 ：低碳钢, 热处理, 组织结构, 微区电化学

Abstract：

The effect of heat treatments on the corrosion behavior of low carbon steels with 3%Cr (mass fraction) in Cl^- containing environment was assessed by means of immersion test, electrochemical measurements, scanning Kelvin probe (SKP), and atomic force microscope (AFM). Results show that annealing leads to single ferrite microstructure, and normalizing causes duplex microstructure consisting of ferrite and bainite. The microstructure difference is the intrinsic reason for the corrosion morphology difference in the initial corrosion stage. In the contrast to the microstructure of annealed steel, the existence of two phases in the normalized microstructure causes galvanic effect, which then resulted in lower corrosion resistance of the steel.

Key words： low carbon steel heat treatment microstructure micro-electrochemistry
