Advanced machinery liquid metal wetting, cleaning and materials compatibility study
Abstract
Electrical machines which employ high current density liquid metal sliprings (current collectors) for current transfer often utilize alkali metals for the conducting fluids. This study was directed at identifying and solving problems associated with the use of liquid NaK78 (78 w/o potassium, 22 w/o sodium) in prototypic machine current collectors. Areas of investigation included: interfacing of recently developed from cleaning procedures with collector electrical performance and investigating collector materials/liquid metal compatibility. This study was supported by the David Taylor Naval Ship Research and Development Center.
