文摘

CNTs reinforced porous CuSn oil bearings were prepared by powder metallurgy method. Surfaced modification of CNTs is made to ensure interfacial bonding between CNTs and CuSn matrix. The micro-structure, micro-hardness, radical crushing strength and oil content of reinforced bearings with different amount of CNTs are investigated. The results reveal that coated CNTs can improve mechanical properties and oil content of the porous CuSn oil bearings if they are evenly dispersed. Adding too much CNTs will degrade microstructure of the porous bearings because they are difficult to disperse. It will bring negative effect on the mechanical properties and oil content of the porous bearings.
