论述了有关CO2腐蚀的机理、影响因素以及防护方法.影响CO2腐蚀的因素有温度、CO2分压、pH值、腐蚀产物膜、溶液离子浓度、合金成分以及流速.简要概述了CO2腐蚀的防护方法.常用的方法加入缓蚀剂、材料选择.
The progress on reseanch of CO2 induced corrosion is reviewed in this paper. The corrosion mechanism and the main factors controlling the corrosion process were also summerized. Temperature, partial presssure of CO2, pH, film of corrosion product and flow rate etc. are important factors to the CO2 induced corrosion. The relevant protection measures are also introduced in this paper which are the use of inhibitors and selectors of material.
