INTERIOR ELECTRODE DESIGNED FOR FORMING SHIELDING FILM AND INSTALLATION FOR FORMING THIS FILM Russian patent published in 2009 - IPC C23C16/509 C23C16/26 

FIELD: metallurgy.

SUBSTANCE: interior electrode for forming shielding film is installed inside plastic container with port and it supplies gaseous medium inside plastic container; it also supplies high frequency power to external electrode located outside plastic container, thus generating plasma of discharge on interior surface of plastic container and creating shielding film on interior surface of plastic container. The interior electrode for forming shielding film consists of a gas supplying tube containing gas propagation path and designed for supply of gas medium and of an insulating element screwed into the end part of the tube so, that it is flushed in it; the insulating element is equipped with a gas outlet communicating with the gas propagation path.

EFFECT: development of electrode for efficient forming of shielding film.
