MoO42-与Zn2+对镁合金在NaCl溶液中的协同缓蚀作用
Corrosion Inhibition Performance of Magnesium Alloy by MoO42-in Combination with Zn2+ in NaCl Solution
摘要
Abstract
The inhibition performance and mechanism of molybdate in combination with Zn2+ as inhibitors for magnesium alloy were studied in 3. 5% NaCl solution by using potentiodynamic polarization curves. The results show that the synergistic inhibition by 0.05 mol/L molybdate in combination with 0. 005 mol/L Zn2+ demonstrates strong inhibition to the corrosion of AZ31 magnesium alloy exposed to NaCl solution. The adsorption acting of Mo042- is promoted on the alloy surface by Zn2+ ,what hold better resistance performance than that of single molybdate corrosion inhibitor. The mixture consisting of molybdate and Zn 2+ is an inhibitor through forming a compact protective layer that covered the magnesium alloy surface.关键词
