摘　　要：在工业应用中,炼油厂塔器容器的耐腐蚀性能对于确保其长期稳定性和安全性至关重要。通过实验方法,深入探讨了不同环境因素对碳钢等材料腐蚀速率的影响,并分析了不同材料在相同腐蚀条件下的表面腐蚀特征。实验结果显示,在酸性环境下,碳钢的腐蚀速率最高,达到0.60 mm·a^(-1),而在中性和碱性环境中,腐蚀速率分别降至0.18 mm·a^(-1)和0.29 mm·a^(-1)。此外,材料表面的腐蚀特征分析揭示了不同材料的耐腐蚀性能差异,聚四氟乙烯表现出最佳的耐蚀性。评价了不同抗腐蚀改性策略的效果,发现涂层处理、热处理和合金化显著降低了碳钢的腐蚀速率,其中合金化效果最显著,腐蚀速率仅为0.15 mm·a^(-1)。In industrial application,the corrosion resistance of refinery column vessels is critical to ensuring their long-term stability and safety.In this paper,experimental methods were used to deeply explore the impact of different environmental factors on the corrosion rate of carbon steel and other materials,and the surface corrosion characteristics of different materials under the same corrosion conditions were analyzed.Experimental results showed that in acidic environments,carbon steel had the highest corrosion rate,reaching 0.60 mm·a^(-1),while in neutral and alkaline environments,the corrosion rates dropped to 0.18 mm·a^(-1) and 0.29 mm·a^(-1) respectively.In addition,analysis of the corrosion characteristics of the material surface revealed differences in the corrosion resistance of different materials,with polytetrafluoroethylene showing the best corrosion resistance.The effects of different anti-corrosion modification strategies and found that coating treatment,heat treatment and alloying significantly reduced the corrosion rate of carbon steel were also evaluated.Among them,alloying had the most significant effect,with a corrosion rate of only 0.15 mm·a^(-1).
