Research Progress of Sacrificial Anode Materials on Amphibian Vehicle

Combined with development and sacrificial anode cathode protection performance requirement of amphibian vehicles,this paper introduces development processes of sacrificial anode material which has been used on amphibian vehicles,and analyzes the effect mechanism of alloy elements.Meanwhile,according to requirements for sacrificial anode performance of bearable dry and wet cycle and experimental results of body potential,the effectiveness of amphibian vehicle under quinary and hexahydroxy alloy sacrificial anode protection is evaluated by those technical indexes such as polarization time,body potential and activation performance.The research trend and key of sacrificial anode cathode protection of amphibian vehicles are prospected.
