In the case of bi- or polymetallic corrosion the catalytic effect may increase the rate of corrosion. In oxygen-free environment those materials promoting evolution of hydrogen may significantly increase the rate of corrosion. In environment containing air those materials increase the rate of corrosion which are catalysts of oxygen ionisation. In chlorine containing environment the chlorides of polyvalent metals may play the role of catalysts. These processes are well known in chemistry but they are often neglected in the theory of corrosion.
