LASER DEPOSITION OF COATINGS

A method of coating a substrate by laser deposition comprises a pre-deposition laser treatment of a surface of the substrate prior to coating. Coating may be carried out on plastics or polymeric materials below the softening temperature. The substrate may be a medical or dental implant, and the coat...

Beschreibung
Zusammenfassung:	A method of coating a substrate by laser deposition comprises a pre-deposition laser treatment of a surface of the substrate prior to coating. Coating may be carried out on plastics or polymeric materials below the softening temperature. The substrate may be a medical or dental implant, and the coating an apatite or hydroxyapatite. The composition, biocompatibility and stability to dissolution in fluids of the coating may be controlled by selection of at least one laser deposition characteristic. La présente invention concerne un procédé de revêtement d'un substrat par déposition au laser, ledit procédé comportant un traitement de prédéposition au laser d'une surface du substrat avant l'opération de revêtement. On peut déposer ledit revêtement sur des matières plastiques ou polymères, en dessous de la température de ramolissement. Le substrat peut être un implant médical ou dentaire, et le revêtement une apatite ou une hydroxyapatite. On peut intervenir sur la composition, la compatibilité biologique et la stabilité relative à la dissolution dans certains fluides du revêtement grâce à la sélection d'au moins une des caractéristiques de déposition du laser.
