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.
摘要翻译： 具有改进的耐磨性的轴承具有铜 - 锡 - 铋合金的轴承材料，其也可以包括由于铜，锡和磷（当使用时）的固溶体而具有优异强度的磷，附着到钢背衬壳 。 由于铋的存在，该材料还具有良好的润滑性，其还在促使使用轴承时促进锡的移动和在轴承表面上形成锡层。 在铜 - 锡 - 基质，特别是Fe 3 P，MoSi 2或其混合物中加入少量相对较小的硬颗粒，提供了合适的硬表面伪影，以改善轴承材料的耐磨性。 轴承包括铜 - 铋合金粉末的烧结粉末紧凑型轴承材料和与钢背衬壳结合的金属化合物粉末，其中金属化合物粉末具有小于10μm的平均粒度。
