| Abstract: | Polarization curve can reflect the details of corrosion dynamic process. So it is the major approach in studying the corrosion behaviors of materials. This paper summarizes researching achievements in passivation and pseudopassivation behaviours of cemented carbides by focusing on polarization curve. It ccvers the study in passivation and pseudopassivation behaviours of series of cemented carbide, including WC-Co, WC-Co-Cr, WC-Ni-Cr, WC-Ni-Co-Cr etc., as well as the study in the formation and growth of passiva- tion film. |
