Abstract
A solid lubricated resistive ink includes solid lubricants which provide self-lubrication of the resistive ink under high vacuum and low moisture conditions. The resistive inks include a polymer-based binder and an electrically conductive solid lubricant which remains electrically conductive and lubricative under low moisture and high vacuum. Effective lubricants include MoSe.sub.2, NbSe.sub.2 graphite intercalated with bromine and graphite intercalated with a metal chloride. The resistive ink may additionally include carbon.
