    Abstract

    The corrosive wear resistance and the damage behavior of metals used for sliding parts in seawater were investigated by changing normal load and sliding speed using a ball on disk tribometer. Sliding wear tests of Fe base and Cu base materials rubbed against Al2O3 were carried out in artificial seawater. The obtained results indicate that Cu base materials show higher corrosive wear resistance and lower coefficient of friction than Fe base materials. Especially, bronze casting alloy shows an excellent corrosive wear resistance, while the corrosive wear of stainless steel is predominantly affected by normal load and sliding speed; that is, higher normal load and sliding speed result in stronger adhesion, leading to higher wear rate.
