采用粉末冶金方法制備（Cu-10Sn）-Ni-MoS₂復(fù)合材料,研究鎳包二硫化鉬對(duì)復(fù)合材料顯微組織、力學(xué)性能和摩擦學(xué)性能的影響。通過(guò)單獨(dú)添加Ni和MoS₂的對(duì)比實(shí)驗(yàn),分析Ni和MoS₂對(duì)復(fù)合材料性能影響的機(jī)理。結(jié)果表明,二硫化鉬顆粒周圍包裹的一層鎳能有效減小二硫化鉬和銅基體的反應(yīng)速率,顯著改善基體的結(jié)合情況。當(dāng)鎳包二硫化鉬的質(zhì)量分?jǐn)?shù)為12%時(shí)（C12）,復(fù)合材料表現(xiàn)出優(yōu)異的力學(xué)性能和摩擦學(xué)性能。C12復(fù)合材料在載荷為8 MPa、線速度為0.25 m/s及油潤(rùn)滑條件下的平均摩擦因數(shù)為0.0075;載荷為4 MPa、線速度為0.25 m/s及對(duì)偶材料40Cr干摩擦條件下的平均摩擦因數(shù)為0.1769。
