Effect of Solubilization-Hydrotrope Action on Corrosion Behavior of Nickel in CTAB-C_5H_(l1)OH/Vc/H_2O Micelle System

摘要

The effect of solubilization-hydrotrope action of vitamin C (Vc) on the corrosion behavior of nickel is studied by electrochemical and SEM methods in a CTAB-C_5H_(l1)OH/Vc/H_2O micelle system. With the increase of Vc content, the solubilization-hydrotrope action and the corrosion rates of nickel increase. But the pure resistance of the system and the differential capacitance on nickel surface decrease. The effect in the CTAB-C_5H_(l1)OH/HCl/H_2O system is less than that in the CTAB-C_5H_(l1)OH/H_2O system.
