Verfahren zur Herstellung einer gradierten Beschichtung aus Calciumphosphatphasen und Metalloxidphasen auf metallischen Implantaten

The invention concerns a process for producing a graduated coating of calcium phosphate phases and metallic oxide phases on metal 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 el...

Beschreibung
Zusammenfassung:	The invention concerns a process for producing a graduated coating of calcium phosphate phases and metallic oxide phases on metal 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 graduated manner is adherent, has a fine structure and is distinguished by a high degree of biocompatibility.
