Abstract


A series of methods for surface modification of Ti-6Al-4V substrates used as materials for medical implants is proposed. Chemical methods of surface modification (35% NaOH and H2O2 solutions as well as 10% HF solution) and physical method of oxygen ion implantation are proposed for TiO2 surface layer formation. Hydroxyapatite coatings on modified surfaces have been deposited by thermal substrate method (tsubstr = 105°С, solution рН = 6.50–6.72, deposition time 120 min). Hydroxyapatite coatings of various morphology and porosity have been obtained. Adhesion strength has been found to increase for coatings obtained on chemically modified surfaces.

Keywords
