Abstract A study on corrosion and cathodic protection of aluminum alloys POD919 and LD 31 used for deepsea submarine robot was carried out in 3.5% NaCl solution.The related electrochemical parameters of three series of sacrificial anodes were determined by constant current discharge method.The results showed that a zinc alloy sacrificial anode was suitable to the protection of submarine robot.Considering the compactness and complexity of the internal structure of the robot,the effects of crevice dimension on cathodic protection ere also studied.The smaller the crevice dimension,the shorter the protection distance.Based on the achieved results,a proposal concerning the design of the cathodic protection system for robot is suggested.

Key words: submarine robot aluminum alloys electrochemical cathodic protection
