采用高温高压釜腐蚀失重法研究了40~350℃范围内,P110钢在高压CO2介质中的腐蚀,对其腐蚀产物宏观和微观形貌、腐蚀产物的成分进行了分析,并对其腐蚀机理进行了探讨。结果表明,高温下CO2腐蚀的主要产物由FeCO3变成了Fe2O3。
The corrosion of P110 steel in high pressure CO2 medium was studied in the temperature range of 40 ~ 350 ℃ by means of high temperature autoclave corrosion loss weighting method. The macroscopic and microscopic morphology of the corrosion products and the composition of corrosion products were analyzed. The corrosion mechanism was also studied Exploring. The results show that the main product of CO2 corrosion changes from FeCO3 to Fe2O3 at high temperature.
