| 摘 要： | 研究以J420焊条焊接Q235钢,其焊缝于亚硫酸铵介质中的腐蚀行为.电化学方法和金相分析表明,Q235钢用J420焊条焊接后,焊缝的组织特点决定了它的耐蚀性低于母材.提高温度,增加亚硫酸铵浓度,均会促使焊缝的腐蚀速率加快. |
| 关 键 词： | 焊缝 亚硫酸铵 电化学腐蚀 |

| Abstract: | The corrosion behavior of welding seam of the Q235 steel jointed by J420 electrode in ammonium sulfite solution was researched.The results of electrochemical method of welding seam and metallurgical structure analysis showed that the poor corrosion resisting property was determined by its structure after the Q235 steel was jointed by J420 electrode.The sulfite corrosion rate was accelerated by increasing the temperature and concentration of ammorium. |
| Keywords: | Welding seam Ammonium sulfite Electrochemical corrosion |
