The fretting wear performance and fretting wear mechanism of four kinds of cladding materials (zirconium alloy,zirconium alloy /Cr coating,FeCrAl and ODS-FeCrAl) were studied on the selfmade fretting corrosion tester.The results show that the friction coefficient,dissipative energy curve and deformation of different cladding materials are significantly different.The four kinds of cladding materials are in the partial slip zone during the frettingwear.〖JP3〗By analyzing the wear scars,it was found that ODS-FeCrAl has better wear resistance than FeCrAl;and Zr/Cr exhibits more excellent wear resistance.
