利用高温高压电化学测试技术，研究了温度对Cr13不锈钢CO₂腐蚀机理的影响.研究表明：90~120℃温度范围内，Cr13不锈钢以点蚀为主，电极反应由活化控制;随着温度的升高，点蚀敏感性逐渐降低，150℃时发生全面腐蚀，而电极反应主要受扩散控制.

By means of high temperature high pressure electrochemical testing facility,the effect of temperature on corrosion of Cr13 stainless steel is studied.The results show that pitting corrosion of Cr13 stainless steel mainly occurred in temperature range of 90℃ to 120℃.The electrode reaction was controlled by activation.With increase of temperature,sensibility to pitting corrosion of the steel was depressed.At 150℃ general corrosion occurred,and electrode reaction was mainly controlled by diffusion.
