    摘要： A bearing having improved wear resistance has a bearing material of a copper-tin-bismuth alloy which may also include phosphorus which has excellent strength, due to the solid solution of copper, tin and phosphorus (when used), attached to a steel backing shell. The material also has good lubricity as a result of the presence of the bismuth which also promotes tin mobilization and formation of a layer of tin on the bearing surface upon use of the bearing. The addition of small amounts of relatively small hard particles in the copper-tin-matrix, particularly Fe3P, MoSi2 or a mixture thereof, provides a suitable hard surface artifact to improve the wear resistance of the bearing material. The bearing includes a sintered powder compact bearing material of a copper-tin-bismuth alloy powder and a metal compound powder which is bonded to a steel backing shell, wherein the metal compound powder has an average particle size of less than 10 μm.

    摘要： A high strength, low friction engineered material includes a low friction material filling interstices of a metal microlattice. The metal typically comprises 5 volume % to 25 volume % and the interstices typically comprise 75 volume % to 95 volume %, based on the total volume of the metal microlattice and the interstices. The low friction material preferably fills 100 volume % of the interstices. The metal microlattice can be formed of a single layer, or multiple layers, for example layers of nickel, copper, and tin. The low friction material is typically a polymer, such as polytetrafluoroethylene (PTFE), polyamide (PAI), polyetheretherketone (PEEK), polyethylene (PE), or polyoxymethylene (POM). The low friction material can also include additive particles to modify the material properties. The engineered material can be used in various automotive applications, for example as a bearing, or non-automotive applications.
