多孔质气体轴承用石墨烯/青铜复合材料的制备及其性能
Preparation and performance of graphene/bronze composite materials for porous gas bearings
摘要
Abstract
To meet the requirements of porous structure and high performance for gas bearings,graphene/bronze porous composite materials were fabricated by combining powder metallurgy and chemical vapor deposition(CVD),and their mechanical and corrosion resistance properties were investigated.The results demonstrated that the addition of nickel reduced defects in graphene and achieved tighter interfacial bonding between graphene and the bronze matrix.The nickel-doped graphene/bronze porous composites achieved a hardness of 103 HV and a tensile strength of 126 MPa,representing 34%and 70%improvements compared with pure porous bronze,respectively.Graphene sheets stacked to form a dense barrier layer.Nickel doping facilitated the formation of compact oxide films on the alloy surface.Compared with porous bronze,the corrosion potential positively shifted from-0.389 V to-0.266 V,so the corrosion resistance of the porous composite was significantly enhanced.关键词
