摘要: 利用人工海水自然浸泡试验、电化学测试和微区电化学试验等研究了退火温度对1060Al/TA2/CCSB钢爆炸复合板在人工海水中的耐腐蚀性的影响。结果表明,复合板在人工海水溶液中主要发生点蚀。随着退火温度的升高,复合板的耐腐蚀性发生变化,在350 ℃时,交流阻抗谱半径最大,在极化曲线中出现了钝化区,电流密度最低,1060Al/TA2与TA2/CCSB钢两个结合界面电位差值最小,复合板的耐蚀性最好。微区电化学测试结果表明,TA2/CCSB钢界面的耐腐蚀性能更好。因此,在经过退火处理后,复合板的耐腐蚀性提高。

Abstract: Effect of annealing temperature on the corrosion resistance of 1060Al/TA2/CCSB steel explosive clad plate in artificial seawater was studied by natural immersion method, corrosion electrochemical method and micro-electrochemical test. The results show that pitting corrosion mainly occurs in the explosive clad plate in the artificial seawater solution. With the increase of annealing temperature, the corrosion resistance of the explosive clad plate changes. When annealing at 350 ℃, the radius of the AC impedance spectrum is the largest, the passivation zone appears in the polarization curve, the current density is the lowest, the potential difference between the two bonding interfaces of 1060Al/TA2 and TA2/CCSB steel is the smallest, and the explosive clad plate has the best corrosion resistance. The micro-electrochemical test results show that the TA2/CCSB steel interface has better corrosion resistance. Therefore, the corrosion resistance of the composite plate is improved after annealing treatment.

Key words: explosive clad plate, annealing temperature, pitting corrosion, microelectron-chemistry, corrosion resistance
