Application and Progress of Sacrificial Anodes Used in the Cathodic Protection of Warships

In this paper, research and development history of Al-alloy sacrificial anodes, Zn-alloy sacrificial anodes and Fe-alloy sacrificial anodes was referred, as well, research status, hotspot and research achievement of corresponding sac- rificial anode products were summarized, meanwhile, ideas that sacrificial anodes used in the special environment and micro-segments market was direction of future development of new anode materials was pointed out. For the Al-alloy sae- rificial anodes, application of Al-alloy sacrificial anodes used in the normal and special environment for the special materi- als including low-driving potential anode in the normal seawater and in the oil seawater, wet-dry cycling, high temperature environment used in the cathodic protection of warships was introduced, meanwhile, research progress of Al-alloy sacrifi- cial anodes used in the ships was summarized; For the Zn-alloy sacrificial anodes, development status, history and corre- sponding Zn-alloy sacrificial anode products used in the warships was referred; For the Fe-alloy sacrificial anodes, status and practical application in the cathodic protection of warship was summarized.
