摘要：

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.
