Accelerated Corrosion Performance Comparison of Several New Grounding Materials
摘 要
通过溶液加速腐蚀试验和电偶加速腐蚀试验对比,研究了我国目前使用较多的几种新型接地材料的耐蚀性,并对比分析了酸碱性环境中各种材料的溶液加速腐蚀速率和电偶加速腐蚀速率。结果表明:在酸性环境中,不锈钢、高硅铬铁和碳纳米改性材料具备良好的耐蚀性,其中高硅铬铁的电偶腐蚀速率最小;在碱性环境中,不锈钢、高硅铬铁和石墨烯复合材料具备良好的耐蚀性,其中石墨烯复合材料的电偶腐蚀速率最小;在中性环境中,不锈钢和高硅铬铁都具备良好的耐蚀性,不锈钢的耐电偶腐蚀性能更好。
Abstract
The performance of galvanic corrosion resistance of several new grounding materials widely used in China were studied by comparison of solution accelerated corrosion test and accelerated galvanic corrosion test. The solution accelerated corrosion rates and the galvanic accelerated corrosion rates of these grounding materials were compared in acid-base property environment. The results show that stainless steel, high-silicon ferrochrome and carbon nano modified materials had good corrosion resistance in acidic environment, and the galvanic accelerated corrosion rate of high-silicon ferrochrome was the least. In alkaline environment, stainless steel, high silicon ferrochrome and graphene composite had good corrosion resistance, and the galvanic accelerated corrosion rate of graphene composite was the least. In neutral environment, both stainless steel and high silicon ferrochrome had good corrosion resistance, and the stainless steel had better galvanic corrosion resistance.
