摘要
为了定量确定黄铜腐蚀与Cl-浓度的关系,对HSn70-1A、HAl77-2A两种黄铜进行静态挂片浸泡试验,并根据试验数据拟合了关系曲线。试验结果表明,在含Cl-的水溶液中HSn70-1A较HAl77-2A腐蚀严重;HSn70-1A、HAl77-2A的腐蚀速度随Cl-浓度的变化均呈三次方关系,区别在于HAl77-2A的腐蚀速度随Cl-浓度的变化较为平缓,而HSn70-1A的腐蚀速度随Cl-浓度的变化较为显著,HSn70-1A的腐蚀对Cl-较HAl77-2A更为敏感。
In order to quantitative determine the relation between brass corrosion and concentration ofCl^-, static coupon test was carried on for two kinds of brasses HSn70-1A and HA177-2A, and experimental data was fitted into curve.The results make clear that there are both cubic relations between corrosion rates of two brasses and C1-concentration, the difference lies in that the corrosion rate change of HSn70-1A brass with C1-concentration is more obvious than HA177-2A, so HSn70-1A brass is more sensitive to corrosion of C1 than HA177-2A brass.
