Abstract: This paper presents a new analytical result between peak current (I_(max)) and sweep rate (v) by a mathematieal model of porous growing layer on the surface of the electrodes of carbon steel. The linear relation between (I_(max)) and (v/I_(max)) is confirmed by linear potential sweep voltammetry.

Key words: Potential sweep method, Passivation, Carbon steel
