摘要
用稳态极化法研究了A3钢在醋酸-醋酸盐缓冲液中的腐蚀行为,讨论了酸度、H2SO3浓度和温度对腐蚀行为的影响 结果表明在HAc NaAc体系中,随着溶液酸度的增加,促进了腐蚀反应阴极过程的进行,加快了A3钢的腐蚀速率;向溶液中加入H2SO3,会促进A3钢腐蚀反应阳极过程的进行,使A3钢的腐蚀速率加快;升高温度会同时加快阴极反应和阳极反应的进行。
The influence exerted by the acidity of solution,the concentration of H_2SO_3 and temperature on corrosion behavior of A_3 steel in HAc-NaAc solutions was studied by means of stable polarization .The experiment results show that the increase of acidity accelerated the cathodal process and accelerated the corrosion rate of A_3 steel.The increase of H_2SO_3 accelerated the anodic process and accelerated the corrosion rate of A_3 steel. The increase of temperature accelerated the cathodal process and the anodic process ,and accelerated the corrosion rate of A_3 steel greatly.
