Abstract

At stell ship's, hull plate material of under water or topside wich is easiest to be hit by corrosion. The mentioned can result, happened thick reduction of plate, easy of leakage effect unable to arrest;detain pressure from uotsid. Losses by corrosion at ship are very big, also require the big expense for the replacement of materials bounce up ship during wich relative shorten. See that way the level of loss generated by corrosion, hence needed some protection from corrosion to pursue or slow down of corrosion rate at hull of ship by addition sacrificial anodes and painting. At corrosion protection wich applcation at hull ship, one of them is addition sacrificial anodes. The sacrificial anodewith application at hull ship are Aluminium anode ( Al ) And Zink anode ( Zn ). The both have the nature of and different characteristic one another ( reffed as potensial differential ) after application at hull ship. Keyword : corrosion, sacrificial anodes, potential differential
