X80钢在酸性红壤模拟液及室外红壤中的腐蚀动力学规律及相关性分析
|
摘要
通过腐蚀失重、SEM和XRD等方法获得了X80钢在酸性红壤模拟液中的腐蚀演变特征;同时,利用精密电阻法原位、连续监测了X80钢在南昌红壤中的长期腐蚀动力学规律;基于室内模拟液腐蚀和室外红壤暴露实验结果,评价了二者之间的相关性,建立了腐蚀寿命预测模型。结果表明,酸性红壤模拟液及南昌红壤中,X80钢的腐蚀失重量与腐蚀时间之间均符合幂函数变化规律(△W=At~n)。通过定性比较和灰关联法分析表明,室内模拟液腐蚀实验与室外红壤暴露实验在腐蚀动力学、腐蚀形貌及腐蚀产物组成上均具有良好的一致性;二者的腐蚀动力学关联度为0.6233。基于室内腐蚀实验建立的GM(1,1)灰色模型可以对室外红壤暴露实验结果进行一定程度的预测,相对误差小于20%。
The evolution characteristics of corrosion-kinetics,-morphology and-products for X80 steel in a simulated acidic soil solution was acquired by means of weight loss measurement, SEM and XRD. Besides, the long-term corrosion-kinetics of X80 steel, which outdoor burried in real red soil at Nanchang district, was monitored in-situ by using a precise electrical resistance(ER) test system. The relevance between the simulated corrosion experiment and the outdoor soil exposure test were evaluated by using qualitative comparison and grey quantitative analysis. The results show that the corrosion weight loss of X80 steel in the simulated solution as a function of exposure time could be calculated using power function(△W=At~n). For the outdoor exposure in red soil, the corrosion kinetics of X80 steel was similar to that of the simulated test. It had good relevance between the indoor corrosion experiment and the outdoor soil exposure test, regardless of the corrosion kinetics, corrosion morphology and the composition of corrosion products. The correlation degree in the corrosion kinetics for the two methods was about 0.6233. Besides, GM(1,1) corrosion kinetic data prediction model had been established basing on indoor immersing experiment. After verification, the relative error of GM(1, 1) prediction model was less than20%, which indicated that GM(1,1) model could be used to predict the outdoor soil exposure test result.
