| 摘 要： | 采用冷压烧结和热挤压方法制备出1. 5～5 vol % SiCP (130 nm) / Al (149～75μm) 复合材料, 并对其抗压、硬度和滑动磨擦特性进行了研究, 旨在研究引入弥散的亚微米级SiCP 对SiCP / Al 复合材料磨擦性能的影响。结果表明: 随着SiCP (130 nm) 含量的增加, 其显微硬度值也增加, 在SiCP (130 nm) 含量为1. 5 vol %和5 vol %时,SiCP (130 nm) Al 复合材料显微硬度分别为28. 4 和33. 3 ; 复合材料的抗压强度分别是170 MPa 和186 MPa ; 在较高载荷下, 随SiCP 含量增加, 复合材料的耐磨性能提高, 1. 5 vol % 和5 vol % SiCP / Al 基复合材料具有优异的滑动磨损抗力, SiCP / Al 基复合材料耐磨性优于挤压态QSn6. 520. 4 和纯Al ; 磨损表面形成Al 基体弥散分布着SiCP和孔隙的理想耐磨组织。

| Abstract: | The pressure properties , Vickers hardness and sliding wear-resistance of 1. 5～5 vol % SiCP (130 nm) / Al(149～75μm) mat rix composites fabricated by powder metallurgy and hot ext rusion were investigated to research theeffect of submicrometer SiCP dispersed in alumina mat rix on the wear behaviour. The result s show that increase inthe volume f raction of SiCP causes Vickers hardness increasing. It s Vickers hardness is 28. 4 and 33. 3 when thevolume f raction of SiCP (130 nm) is 1. 5～5 vol %. The pressure properties of the material are 170 MPa and 186 MParespectively. Under the higher load , the sliding wear - property increases with increasing the volume f raction ofSiCP ; 1. 5 vol % and 5 vol % SiCP / Al composites have higher sliding wear-behavior than 61520. 4 bronze bearing material and Al. An excellent wear-resistance microst ructure consisting of aluminum mat rix and minute hole and homogeneous dist ribution SiCP is formed in the wear surface of SiCP / Al mat rix composites. |
