Surface Attack on Metals in the Presence of Liquid Metals.
Abstract
A study has been undertaken to evaluate liquid metals as electrical collectors in contact with solid metal alloys. Surface attack of the liquid metal on the solid metal is expected to be a major challenge to the development of a credible system. Low melting temperature metals and alloys of the fusible type are to be utilized for a collector that will operate in the 200-500 F range, with emphasis towards the lower end. Solid metals have been selected for experimental work based on their electrical properties and minimal potential reaction with the candidate liquid metal alloys. Material properties of both liquid and solid metals were reviewed to identify initial material combinations for evaluation. Thorough literature searches were conducted to obtain as much pertinent physical property and metallurgical data as possible, prior to actual experimental work. Process and material modelling was adopted to select candidate materials for both solids and liquids. Consideration of practical requirements for the eventual collectors is an integral part of the study. Work effort has concentrated on apparatus construction, evaluation and a program of testing to obtain screening data on materials selected and the chosen test method. Results have identified limitations of the test unit design and maximum current loads under test conditions with experimental current collectors. Candidate electrode materials have been exposed in low melting fusible alloys for direct dissolution data.
