[Biocompatible coatings for metallic implants obtained by laser spraying]

Use of various lasers and regimens for spraying the coatings and for additional thermal processing makes it possible to purposefully alter the morphology, composition, and crystallinity of the coatings, and hence, the optimal coatings, as regards their biological activity, may be created. Replacement of eximer lasers with CO2 lasers makes the spraying process cheaper and comparable in efficacy with the plasma process, with the quality of coatings and reproducibility of their parameters appreciably improved. Experiments with coatings of three types, sprayed by CO2 lasers, demonstrated that they met the mechanical and physico-chemical requirements of biocompatibility.
