Friction and Wear Studies of Liquid Metal Wetted, Metallic Fiber Brushes.

Abstract

Metallic fiber brushes wetted with a liquid metal could potentially provide a current collector for large scale homopolar machinery. This study deals with the investigation of brushes composed of Niobium fibers in a copper matrix and wetted with the liquid metal, Nak78. Four brushes with different fiber diameters and packing densities have been studied. Brushes have been characterized according to stiffness and values of the coefficient of friction for both dry and Nak78 wetted brushes have been obtained. Preliminary wear studies indicate that if brush bounce can be avoided, lifetime should be suitable. (Author)
