摘　　要：为降低铜基含油轴承的制造成本,同时满足强度和耐腐蚀性等要求,采用粉末冶金技术,在氮气气氛中920℃烧结120 min,制备铝质量分数为15%的含铝铜基烧结含油轴承,分析烧结试样的性能和微观结构,在此基础上,进一步探讨铝的质量分数分别为10%、15%、20%和25%时对烧结试样性能和微观形貌的影响。结果表明,当铝的质量分数为15%时,烧结试样具有良好的综合性能,压溃强度和含油率分别为170.90 MPa、8.32%。In order to reduce the production cost of Cu-based sintered oil bearing and meet the requirements of strength and corrosion resistance,the Cu-based sintered oil bearing(containing 15%Al by mass)was prepared by powder metallurgy technology at 920℃for 120 min in N2 atmosphere.The properties and microstructures of the sintered samples were measured.Further,the effects of Al content,with 10%、15%、20%and 25%,on the properties and microstructures of the sintered samples were investigated.The results show that,the optimal properties of the sintered samples are obtained when the mass fraction of Al is 15%,and the crushing strength and oil content reaches 177.90 MPa and 9.43%,respectively.
