Abstract

The paper describes perspective technology for deposition of inorganic-organic coatings used for biomedical\ud application. Synthetic hydroxyapatite was used as inorganic compound, due to the similarity of the\ud main component to bone tissue. As organic components we used chitosan and alginate – natural biopolymers,\ud which widely used for bioactive and biocompatible composites formation. Thermal substrate method\ud used for coatings deposition based on principle of decreasing solubility of hydroxyapatite with increasing of\ud substrate temperature and allow to deposit coatings at substrate temperatures below 100 °C. Porous composite\ud hydroxyapatite-chitosan and hydroxyapatite-alginate coatings were obtained on Ti-6Al-4V substrates.\ud Morphology, phase composition and adhesion to the substrate surface were investigated.
