The soil factors that affect the

The presence of chloride increases the rate of oxidation and resulting corrosion, especially of Fe. Depending on the metal type and the 'LY2157299' solutes present, initial corrosion processes may create a protective layer that slows corrosion further: these layers may include oxides (e.g., Al2O3), phosphates (e.g., FePO4) and carbonates (e.g., CuCO3). Under reducing conditions, biological activity may encourage the formation of sulphides that slow corrosion that is already being inhibited by a lack of free oxygen.
