Under a Research Initiation Award the relationship between processing, microstructure and tribological behavior will be studied for copper alloy composites with chromium fiber reinforcements. The effects of high load and velocity will be evaluated under conditions where large electrical currents pass across the interface between the composite and a hardened steel counterface, simulating the conditions of electrical brushes in homopolar motors and similar applications. The resistance to arc erosion and to oxidation will also be evaluated.

在研究启动奖的指导下，将研究含铬纤维增强铜合金复合材料的加工、显微组织和摩擦学行为之间的关系。高负载和高速度的影响将在大电流通过复合材料和硬化钢对接表面之间的界面的条件下进行评估，模拟同极电机和类似应用中的电刷条件。还将评估其抗电弧侵蚀和抗氧化性。
