ABSTRACT:
In ionization electrostatic plating, a cathode is incorporated separately of the article subjected to plating which has conventionally been adapted to function as makeshift cathode. The electric circuit to said article is designed to permit flow of electric current which is wholly consumed for heating the article to a temperature required for plating, so that the article will no longer play the main part of a cathode for glow discharge.
This method prevents the film of plating material deposited on the article from breaking, heightens the plating efficiency and, consequently, provides highly desirable plating of metal and also non-metal articles.
