摘      要：Stainless steels such as STS 304,316 and 630 are frequently used as shaft materials in small fiber reinforced polymer(FRP) fishing *** the shaft material is exposed to a severely corrosive environment such as seawater,it should be protected using appropriate *** impressed current cathodic protection was used to inhibit corrosion in shaft *** anodic polarization,passivity was remarkably more evident in STS 316 stainless steel than in STS 304 and STS *** pitting potentials of STS 304,316,and 630 stainless steels were 0.30,0.323,and 0.260 V,*** concentration polarization due to oxygen reduction and activation polarization due to hydrogen generation were evident in the cathodic polarization trends of all three stainless *** 316 had the lowest current densities in all potential ranges,and STS 630 had the *** analysis showed that STS 316 was the most noble in the *** addition,the corrosion current density was the lowest for STS 316.
