Factors Which Affect Corrosion, Chemistry Study …

Factors which Affect Corrosion. The main factors which affect corrosion are. 1.More the reactivity of metal, the more will be the possibility of the metal getting corroded. 2.The impurities help in setting up voltaic cells, which increase the speed of corrosion. 3. Presence of electrolytes in water also increases the rate of corrosion. 4.
