Design of Bearing Materials for Sliding Applications

含硬质和/或软质成分的铝合金的摩擦学行为将被研究。目的是制定用于滑动应用（如汽车应用）的轴承材料的设计指南，希望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，包括对Al-Pb、Al-Si、Al-Pb- si合金以及更复杂的成分进行摩擦学测试和测试后的表征，这些成分具有严格控制的二次相尺寸和分布。这项工作包括与切尔尼戈洛夫卡的俄罗斯科学院固体物理研究所的合作。该研究所开发了一种基于磁场和电场的技术，用于在非混相成分的大块材料中生产非常精细的微观结构，如Al-Pb和al -石墨，并将提供用于测试的各种合金。＊＊＊

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. ***
