摘要

用扫描电镜、能谱分析和X射线衍射方法

从质量变化、显微结构形貌及生成腐蚀产物成分、元素分布等方面

对 15CrMoG和 2 0号钢在不同温度下

在N2 5 %O2 30 0 μL/LHCl混合气氛中的腐蚀行为进行了研究

得出了腐蚀恒温动力学曲线。对腐蚀产物的成分、形貌进行分析

发现这两种材料在相同温度、相同气氛中的腐蚀量相差不大

抗腐蚀性能均不佳。在含氯氧化环境中

氯的存在引起了活性氧化

加速了腐蚀。

Abstract

The corrosion behavior of 15CrMoG and No.20 steels in mixed atomosphere of N

5%O

300μL/L HCl under different temperatures has been studied by means of scanning electronic microscope

energy spectrum analysis

and Xray diffraction etc. from aspects of mass variation

appearance of microstructure

composition of corrosion products and elements distribution etc.

obtaining corrosionconstant temperature kinetic curve

and analysing the composition and appearance of corrosion products. It is found that the difference of corrosion degree for two metallic materials to be small under same temperature and in same atmosphere

and their corrosionresitant property to be all no good. In oxidizing environment with chlorine content

the existence of chlorine leads to activated oxidation

making corrosion to be accelerated.
