Abstract

The copper-based FGMs were prepared by vacuum hot pressing

and the hardness

conductivity and density of the copper-based FGMs prepared were measured.Wear behavior was tested by high-temperature friction and wear sampler which was used in vacuum and controlled by MMU-5GA microcomputer.Microstructure and grinding crack morphology were analyzed by the JSM-5610LV scanning electron microscopy and XRD Diffractometer.The results show that functional gradient materials with sound and homogeneous structure can be obtained

and the matrix is distributed continuously with desirable bonding interface and metallurgical bonding layer.The FGMs samples exhibit the higher physical properties and friction and wear performance with ball milling for 40h

compared with the sample for 20 hours.
