Abstract (en)

[origin: EP0366941A1] A process is described for the electrophoretic coating of chromisable metal surfaces. An improvement in adhesion of the coating is achieved by a chromising pretreatment of the metal surfaces, the chromised metal surfaces being kept wet in the period from chromising until introduction into the electrophoretic coating bath.
