Abstract:

The corrosion of Ni in HCl(aq) solution can be inhibited in three typical surfactant systems. The order of the inhibition efficiency and the corrosive active energy is CTAB > Triton X-100 > SDS. The cosurfactant butanol can be used as inhibiting adjuster, and can control and change the corrosive rate of Ni in HCl(aq)solution. The order of the corrosive rate in different medium is HCl(aq) > surfactant+ butanol+ HCl (aq) > surfactant+ HCl(aq) > surfactant+ butanol(aq) >surfactant(aq).

Key words: Nickel, Surfactant, n-Butanol, Corrosion
