Abstract: The invention concerns a process for producing a gradient coating of calcium phosphat phases and metal oxide phases on metallic implants, in particular made of titanium or titanium alloys, for use as dental, jaw or joint implants. A solution containing calcium ions and phosphate ions is used as electrolyte of which the pH is slightly acidic to approximately neutral. The substrate electrodes are alternately polarized cathodically and anodically. The layer deposited in a gratuated manner is adherent, has a fine structure and is distinguished by a high degree of biocompatibility.
