Investigation of the Performance of Tungsten-Cobalt Plated Slip Rings and Commutators

Abstract

An electroplated alloy of tungsten and cobalt on copper has been given limited tests under sea level and simulated high-altitude conditions. The first series of tests, made with a slip ring and a dummy commutator under conditions of low temperature, humidity, and pressure, gave results which were favorable when compared to results on copper. Further tests of an actual aircraft generator at sea level have given unsatisfactory results to date. Mechanical difficulties may have contributed to this poor operation.
