Abstract

L'invention concerne un procédé pour produire un revêtement à gradiants constitué de phases de phosphate de calcium et de phases d'oxyde métallique sur des implants métalliques, notamment en titane ou en alliages de titane, pour des utilisations comme implants dentaires, maxillaires ou articulaires. Une solution contenant des ions calcium et des ions phosphate est utilisée comme électrolyte, le pH de cette solution étant légèrement acide à approximativement neutre. Les électrodes du substrat présentent une polarisation alternée cathodique et anodique. La couche déposée par gradients est adhésive, présente une structure fine et se distingue par une biocompatibilité élevée.
