PROCESS FOR THE ELECTRODEPOSITION OF PHOSPHOCALCIUM COATINGS ON METALLIC SUBSTRATES, COATINGS OBTAINED AND IMPLANTABLE MATERIALS COMPRISING SUCH COATINGS

摘要

The invention relates to a process for the electrodeposition of phosphocalcic coatings on a metal support comprising the electrolysis of a solution containing calcium ions and phosphate ions. The application of a pulsed electric current between the cathode support and a counter electrode, the electrolyte comprising a solution of Ca (NO), 4H O and NH H PO makes it possible to obtain hydroxyapatite coatings. compact and adhering to the support. The invention also relates to implantable materials comprising such coatings.
