摘要：
Corrosion behavior of A6061 aluminum alloy in cation containing simulated aqueous medium was investigated by surface analysis techniques and electrochemical tests.The mass of specimens was increased after the immersion tests,and a smaller mass change was observed in the Zn2+containing solution.Electron microscopic images showed the deposited products on the specimen that were Al-hydroxide confirmed by X-ray photoelectron spectroscopy.Zn-layer was formed on the specimen immersed in Zn2+containing solution,and corrosion inhibition of Al resulted in a smaller number of Al products deposited on the alloy surface.Electrochemical results showed higher impedance in the Zn2+containing solution due to the formation of the Zn related layer on the surface with oxide film.
