Abstract
Method for coating an electrically conductive article, characterized in that it comprises immersing the article in a dispersion of film-forming ionized material and a counter-ion and passing an electric current between the article and a counter electrode in electrical contact with the dispersion, a first region of the dispersion, by means of an ion-conducting bridge, to a second region of the dispersion that has a lower electrical accessibility to the counter electrode than that of the first region.
