Study on Properties of thin Tungsten Coatings Prepared in Na2WO4 Molten Salt

open access: yesInternational Journal of Electrochemical Science, 2019
In this paper, tungsten coatings on copper substrates were prepared by electro-deposition from a Na2WO4 molten salt system at 1173K. The coating composition, microstructure, and morphology were studied via XRD, SEM, EDS, and LSCM.

Characterization of a spheromak plasma gun: The effect of refractory electrode coatings [PDF]

open access: yes, 1991
In order to investigate the proposition that high-Z impurities are responsible for the anomalously short lifetime of the Caltech spheromak, the center electrode of the spheromak plasma gun has been coated with a variety of metals (bare steel, copper ...
