Abstract

The effect of synergy of water pressure and water flow on the free-corrosion behavior of Al-Zn-In alloy, a common Al-based sacrificial anode material, was studied via a home-made test set for regulating water pressure and flow rate aiming to simulate the deep-sea environment. The results show that both the water pressure and water flow could promote the free-corrosion of the Al-Zn-In sacrificial alloy. The effect of the water flow is obviously greater than that of water pressure. Under high water pressure, the diameter and depth of the corrosion pits increased. By high water flow rate, the number of pits increased significantly, and the electrochemical reaction resistance decreased. In addition, the erosion effect of flowing water on the alloy substrate may enhance the falling-off process of grains from the alloy. Generally, the free-corrosion of Al-Zn-In sacrificial alloy is significantly enhanced in the presence of synergetic effect of electrochemical corrosion and water erosion.

Key words: hydrostatic pressure flow sacrificial anode self-corrosion
