Design of Bearing Materials for Sliding Applications

9509624瑞格尼将研究含有硬和/或软成分的铝合金的摩擦学行为。其目的是为滑动应用(如汽车使用)中使用的轴承材料制定设计指南，希望其结果将允许逐步淘汰这些材料中的铅。这项工作主要是试验性的，涉及Al-Pb、Al-Si、Al-Pb-Si合金的摩擦学测试和测试后表征，以及更复杂的成分，其中第二相的大小和分布受到严格控制。这项工作包括与位于切尔尼戈洛夫卡的俄罗斯科学院固态物理研究所合作。该研究所开发了一种基于磁场和电场的技术，可以在不相容成分的块状材料中产生非常精细的微观结构，如Al-Pb和Al-石墨，并将提供各种合金供测试。***

9509624 Rigney The tribological behavior of aluminum alloys containing hard and/or soft components will be studied. The purpose is to develop guidelines for the design of bearing materials for use in sliding applications, such as automotive uses, with the hope that the results will allow the gradual phase-out of lead in these materials. The work is primarily experimental and involves tribological testing and post-test characterization of Al-Pb, Al-Si, Al-Pb-Si alloys as well as more complex compositions with closely controlled size and distribution of the secondary phase. The work includes a collaboration with the Russian Academy of Sciences Institute of Solid State Physics in Chernigolovka. That institute has developed a technique based on the use of magnetic and electric fields for producing very fine microstructures in bulk materials of immiscible components, such as Al-Pb and Al-graphite and will provide the various alloys for testing. ***
