Development of apparatus and technology for creation of a superconducting niobium coating on the cryogyroscope rotor

Abstract

The processes of creating a superconducting niobium coating on a cryogyroscope rotor were considered. The conditions for the electrodeposition of superconducting niobium coatings from molten salt on rotors of a cryogenic gyroscope were determined. Niobium coatings obtained from molten salt were electrochemically polished and subsequently protective coating of niobium pentoxide was electroformed. The processes occurring during the electrodeposition, electropolishing and electrooxidation of niobium were considered. The equipment and technology for creating a superconducting niobium coating on the rotor of a cryogenic gyroscope was developed.
