Abstract
In the present work octadecyltrimethoxysilane (ODTMS) was deposited on mild steel in one and two-step treatments for corrosion resistance against a chloride medium (with and without sulphate reducing bacteria (SRB)). Electrochemical results showed that a hydrolysis of ODTMS for 3 h at pH 4 was sufficient for achieving a considerable enhancement in corrosion protection due to just one-step coating. However, corrosion resistance was found to be significantly superior due to the two-step treatment. The influence of the coating developed upon two-step treatment on the corrosion resistance of mild steel in the chloride solution containing SRB was assessed using comprehensive electrochemical analysis.
