Abstract
Process for the pre-treatment of non-ferrous metals or alloys serving as foundation parts for dentures and the like to be covered electrophoretically with ceramic material, which comprises plating the foundation parts with zinc by electrolysis before carrying out the ceramic layer formation, the zinc plating being of a thickness to allow the entire metallic zinc to become oxidized by the oxygen generated by electrolysis occurring simultaneously with the electrophoretic layer formation of ceramic material, the zinc oxide forming a bridge to secure the ceramic cover layers to adhere to the non-ferrous metal parts.
