| 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 ,有的甚至腐蚀率为零

| Abstract: | 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. |
