METHOD OF ELECTROPOLISHING OF METALS IN A GASEOUS MEDIUM Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: the invention is dealt with electropolishing of surfaces of metal parts of the vacuum and high-voltage devices. The invention presents the method of electropolishing of metals in a gaseous medium, The method provides for placement of a workpiece in a vacuum chamber and formation of a high electric field strength at the workpiece surface. At that in the vacuum chamber they introduce an additional substance - an intermediary, in particular, water to facilitate removal of the atoms acting above the surface. Then conduct a polish process maintaining the electric field strength near the working surface at a level of 10⁸-5·10⁹ V/m, i.e. less, than it is required for the field to transpirate the material. The technical effect of the invention is a capability to decrease by an order the values of the electric voltage necessary for production of an atomically smooth surface.

EFFECT: the invention is capable to decrease by an order the values of the electric voltage necessary for production of an atomically smooth surface.
