采用SEM,EDS,XRD等研究了紫铜T2在高浓度H2S环境中的腐蚀行为和规律,同时建立了非等间距灰色GM(1,1)数学模型,并对该模型的精度和合理性进行了检验。结果表明,实验初期腐蚀增重量增加缓慢,后期增加迅速;腐蚀产物出现分层并且产生裂缝;腐蚀产物主要是Cu2S和Cu2O;数学模型具有较好的拟合精度和较高的预测可靠性。 The corrosion behavior and regularity of red copper T2 in high-concentration H2S environment were studied by SEM, EDS and XRD. At the same time, a non-equidistant gray GM (1,1) mathematical model was established and the accuracy and rationality of the model were also studied test. The results show that the corrosion weight increase slowly at the beginning of the experiment and increase quickly in the later period; the corrosion products are delaminated and cracked; the corrosion products are mainly Cu2S and Cu2O; the mathematical model has better fitting accuracy and higher reliability.
