摘要
烧结青铜(6-6-3)-铁轴承材料具有比烧结青铜(6-6-3)更好的机械性能和摩擦磨损性能。铁元素的加入,使烧结尺寸变化(负值)降低,形成了具有均匀金相组织的铜-铁假合金。研究了铁含量和烧结温度对试样烧结尺寸交化、力学性能和摩擦磨损性能的影响,分析了影响机理。
Sintered bronze(6-6-3)-iron bearing materials are superior to bronze(6-6-3) bearing materials in mechanical and frictional properties and wearafility. The addition of iron element decreases demensional shrinkage ratios during sintering. Iron and copper form Cu-Fe pseudo-alloy with homogeneous microstructure. The influences of iron contents and sintering temperatures on the dimensional shrinkage ratio and mechanical and frictional properties and wearafility have been studied. The mechanism of influence has been analysized
