Abstract: Corrosive wear,which is widely found in mechanical equipment of oil,chemical,mining and electrical industries,is one of the main reasons which induce material loss andequipment failure,Studies on corrosive wear have been earried out recent years,but there are manyproblems in corrosive wear testers and no special testers for experiments of corrosive wear.So threetypes of corrosive wear testers,which had good operating performance and could be used fordifferent purpose study,have been designed and man ufactured in our laboratory.The steady testercan be used not only for evaluating corrosive wear properties of metals in different corrosivemediums but also for studying mechanism of corrosive wear.Transient information of metal surfacebeing scratched in different corrosive mediums can be obtained from the transient tester.The slurryerosion tester can be used for evaluating corrosive wear property of metals in simulative conditions,this is important to mechanism study and material selection. Corrosive wear behavior of AISI 316Land dupiex stainless steel was studied by using these testers.The results indicate that these testerspossess good operating performances and can be used for studying corrosive wear systematically.
