In this paper, the effects of different chloride ion (Cl-) concentrations on corrosion behavior of T91 steel treated by indentation method in the neutral salt spray environment are studied. The corrosion test of 48~288 h for indentation specimens is carried out with NaCl solutions of concentrations of 10% and 15% under the standard neutral salt spray test conditions. It is found that the corrosion weight loss in the environment of 15% NaCl is higher than that in the environment of 10% NaCl through analyzing the corrosion weight loss, corrosion morphology and corrosion products as well as the difference between them is increased with the extension of corrosion time, which reaches the maximum value (0.008 5 g) at 288 h. This proves that the corrosion effects of environment with high Cl- concentration on T91 steel are stronger and they are obvious with time accumulation. The observation results of scanning electron microscope showed that the indentation was more easy-corrosive and the more the Cl- concentration, the more serious the corrosion was, which indicates that the corrosion resistance in this area is significantly reduced by stress concentrations (dislocations, microcracks etc.) introduced by indentation so that it becomes the sensitive area where corrosion occurs preferentially.

文章研究了不同氯离子(Cl-)浓度对经压入法处理的T91钢在中性盐雾环境中腐蚀行为的影响。采用10%和15%两种浓度的NaCl溶液,在标准中性盐雾试验条件下对压入试样进行了48~288 h的腐蚀试验。通过分析腐蚀失重、腐蚀形貌及腐蚀产物,发现15% NaCl环境下的试样腐蚀失重高于10% NaCl环境,且两者差距随腐蚀时间延长而增大,在288 h时达到最大值0.008 5 g。这证明高Cl-浓度环境对T91钢的腐蚀作用更强,且随时间累积效应明显。扫描电子显微镜观察结果显示,压痕处更易腐蚀,且Cl-浓度越大腐蚀越严重,表明压入形成的应力集中(位错、微裂纹等)显著降低了该区域的耐蚀性,使其成为优先发生腐蚀的敏感区域。

文章研究了不同氯离子(Cl-)浓度对经压入法处理的T91钢在中性盐雾环境中腐蚀行为的影响。采用10%和15%两种浓度的NaCl溶液,在标准中性盐雾试验条件下对压入试样进行了48~288 h的腐蚀试验。通过分析腐蚀失重、腐蚀形貌及腐蚀产物,发现15% NaCl环境下的试样腐蚀失重高于10% NaCl环境,且两者差距随腐蚀时间延长而增大,在288 h时达到最大值0.008 5 g。这证明高Cl-浓度环境对T91钢的腐蚀作用更强,且随时间累积效应明显。扫描电子显微镜观察结果显示,压痕处更易腐蚀,且Cl-浓度越大腐蚀越严重,表明压入形成的应力集中(位错、微裂纹等)显著降低了该区域的耐蚀性,使其成为优先发生腐蚀的敏感区域。

In this paper, the effects of different chloride ion (Cl-) concentrations on corrosion behavior of T91 steel treated by indentation method in the neutral salt spray environment are studied. The corrosion test of 48~288 h for indentation specimens is carried out with NaCl solutions of concentrations of 10% and 15% under the standard neutral salt spray test conditions. It is found that the corrosion weight loss in the environment of 15% NaCl is higher than that in the environment of 10% NaCl through analyzing the corrosion weight loss, corrosion morphology and corrosion products as well as the difference between them is increased with the extension of corrosion time, which reaches the maximum value (0.008 5 g) at 288 h. This proves that the corrosion effects of environment with high Cl- concentration on T91 steel are stronger and they are obvious with time accumulation. The observation results of scanning electron microscope showed that the indentation was more easy-corrosive and the more the Cl- concentration, the more serious the corrosion was, which indicates that the corrosion resistance in this area is significantly reduced by stress concentrations (dislocations, microcracks etc.) introduced by indentation so that it becomes the sensitive area where corrosion occurs preferentially.
