摘　　要：通过分析旋转挂片法腐蚀后水样中的Cu2 + 和Zn2 + 含量总和 ,来测定水中常见几种离子 (Cl-、SO42 -、Cu2 + 、Fe3 + 、Zn2 + 和NH3 )对铜合金HSn70 1B的腐蚀情况。研究表明 ,这几种离子对铜合金HSn70 1B的腐蚀随着浓度的变化整体呈现一定的规律。在一定的浓度范围内这几种离子对铜合金的腐蚀率很小 。Through analyzing the total content of the Cu^(2+) and Zn^(2+) in water sample after the corrosion of the rotating copper alloy HSn70-1B sample slices suspended in the water,the corrosion behavior of the common ions in water,namely Cl^-?SO 4^(2-)?Cu^(2+)?Fe^(3+)?Zn^(2+) and NH 3, to the copper-alloy HSn70-1B was tested.The study showed that the corrosion behavior of these ions to the copper alloy HSn70 -1B presents a certain rule with the change of their concentration.Within a certain concentration range their corrosion to the copper-alloy is extremely slight and some of them (even) present a zero corrosion rate.
