摘　　要：耐腐蚀钢在实际应用中存在直接埋入地下使用的情况,且土壤腐蚀是最重要的实际腐蚀问题之一,通过对比分析Q235B、09CrCuSb和SPA-H三个钢种在地埋腐蚀试验中的腐蚀形貌,完成了钢种地埋腐蚀试验的耐腐蚀性能评价对比,逐步了解了耐腐蚀钢在土壤中的腐蚀机理及规律,为耐腐蚀钢在土壤环境中的使用提供了依据和指导。Corrosion resistant steel is directly buried underground in practical application,and soil corrosion is one of the most important practical corrosion problems,through the comparison and analysis of the corrosion morphology of Q235B、09CrCuSb and SPA-H steel in soil corrosion,the corrosion mechanism and law of the corrosion resistant steel in the soil corrosion are mastered,the evaluation of corrosion resistance of them in soil corrosion are completed,this study provides basis and guidance for the use of corrosion resistant steel in soil environment.
