The wear properties of GCr15 steel with salt bath furnace heat treatment and mesh belt furnace heat treatment were tested against Si3N4 ceramic ball under dry friction condition by using selfmade rapid wear test machine,the profiles of GCr15 steel wear surfaces were observed by White Light Interferometer (WLI) and Scanning Electron Microscope(SEM),the wear volume of GCr15 steel was calculated by SPIP 3D graphic analysis software.The results show that the GCr15 steel with mesh belt furnace heat treatment has smaller average dry friction and wear volume against Si3N4 ceramic ball compared with that with salt bath furnace heat treatment,and its antiwear properties are better under multiple experimental conditions.The wear failure mechanism of GCr15 steel by two heat treatment methods is fatigue wear,while the wear performance of GCr15 steel with mesh belt furnace heat treatment is improved,the wear surface of the test sample is relatively smooth and has less wear fatigue crack,and the plastic deformation is reduced.
