Corrosion Bockris mechanism

Corrosion current density was obtained from extrapolation of tangents to anode potentiokinetic curves with the slop>e of 0.04 V/ decade (it was adopted that the process of anode solubilisation of the sintered steels occurs according to Bockris mechanism [53-54]). The extrapolation method allowed for evaluation of the corrosion rate in composites.
