| 摘 要： | 用失重法研究了4种金属离子(Na+,Zn2+,Cu2+,Fe3+)在0.5 mol/L H2SO4以及500 mg/L没食子酸+0.5 mol/L H2SO4介质中在20℃对冷轧钢腐蚀行为的影响.结果表明:Cu2+对钢的腐蚀起抑制作用;而其余3种金属离子(Na+,Zn2+,Fe3+)对钢的腐蚀起加速作用.在相同条件下,冷轧钢在0.5 mol/L H2SO4溶液中的腐蚀速率顺序为:Cu2+ |

| Abstract: | The corrosion behavior effect of metallic cations(Na+,Zn2+,Cu2+,Fe3+) in H2SO4 /gallic acid solution at 20 ℃ on the cold rolled steel was studied by weight loss method.The results showed that Cu2+ inhibit the corrosion of cold rolled steel,whereas the other metallic cations accelerate the steel corrosion.In 0.5 mol/L H2SO4 solution,the corrosion rate of cold rolled steel follows the order:Cu2+ |
| Keywords: | steel gallic acid metallic cations corrosion |
