This paper introduces the research status and present situation of application of Pt/Ta composite anode materials for cathodic protection in China. It also introduces the corrosion resistance, bending properties and electrochemical performance in seawater and freshwater of the Pt/Ta composite anode materials for cathodic protection. It points out that compared with other platinum composite anodes, the Pt/Ta composite anode has the advantage of small volume, light weight, big drainage rate, long service life, it possesses superiority to be used in the confluence environment of sea water and fresh water and in the medium condition of resistivity changes at all times.
