- •
Pitting corrosion of steel is effectively reduced by the addition of provitamin B5.
- •
The techniques include potentiodynamic anodic polarization and chronoamperometry.
- •
Physically adsorbed provitamin B5 on the metal surface restricts the corrosion.
- •
Efficiency increased by increasing provitamin B5concentration.
- •
Efficiency decreased by increasing solution temperature and flow rate.
