Zn的大气腐蚀与寿命预测研究
|
摘要
对锌板和Zn开放型螺旋两种试样在福建省16个地点进行了为期1 a的大气暴露试验,获得了Zn在不同大气环境下的腐蚀速率,并结合各地区的气象和环境数据使用锌层寿命预报器(ZCLP)对Zn的腐蚀速率进行了预测。结果表明,Zn的腐蚀速率与大气环境有直接的关联,除福清、厦门和南安等地区,其他13个地点Zn的腐蚀速率的预测值与通过大气腐蚀暴露试验获得的Zn的腐蚀速率实测值吻合,结合Zn的腐蚀机理对大气腐蚀暴露试验获得的Zn的腐蚀速率的可靠性进行了分析。
Two kinds of Zn specimens with flat-and helix-shape respectively were exposed in atmospheres at 16 test sites in Fujian province for 1 a. The corrosion rates of Zn specimens in different atmospheric environments were collected, in the meanwhile the relevant corrosion rates of Zn were predicted by using a zinc coating life predictor(ZCLP) by taking the meteorological and environmental parameters of each test site into account. The results show that the corrosion rate of Zn is directly related to the atmospheric environment parameters. Except for the test sites in areas of Fuqing, Xiamen and Nan'an, the predicted values of corrosion rate of Zn are consistent with the measured values for the other 13 test sites. Finally, the reliability of corrosion rate of Zn obtained by atmospheric corrosion exposure test was analyzed in conjunction with the corrosion mechanism of Zn.
