  • Process for application of an inorganic coating to an electrically conducting body
    Patent number: 6153270
    Abstract: A process of applying an inorganic coating to an electrically conducting body, in particular a metallic workpiece, is characterized with respect to a precisely controllable temperature variation with short temperature changes in an economical and energy-saving operation in that the body first undergoes a preparation. Thereafter, if need be, the body is degreased and/or chemically pretreated and/or blasted. Subsequently, a coating medium is applied to at least the surface region of the body being coated. Then, at least the surface region of the body being coated is heated by induction to a reaction temperature before and/or while and/or after applying the coating medium. Finally, the coating medium is fully reacted to a coating, whereupon the body undergoes a cooling.
