Abstract:
In this presentation results of studies of electrodeposition of refractory metals from molten salts and manufacturing of near-net shape components performed at Plasma Processes, Inc will be outlined. High melting point and strength are driving the increased utilization of refractory metals for high temperature applications. Molten salts electrolysis offer unique opportunities to deposit dense, coherent layers of refractory metals with desired shape and very low impurities level. Because of high temperature and high reactivity of melts, containing refractory metals salts, special equipment for high temperature electrolysis has been designed and built. Utilization of oxidation and corrosion resistance materials for melt containers and electrolyzers, electrolysis under inert atmosphere and tight process control provide stable and reproducible properties of electrodeposited metals. Influence of parameters of electrolysis and annealing on structure and properties of refractory metals was investigated. Electroforming techniques have been developed to produce near-net shape components from iridium, rhenium, niobium, hafnium and tungsten. The electrodeposition from molten salts has been demonstrated as a viable fabrication tool for commercial application. Various examples of the electroformed product and coating will be presented.
