Abstract. The gas-detonation technique was used for the synthesis of biocompatible hydroxylapatite-based protective coatings on polymer and titanium substrates. Hydroxylapatite powder of high purity with a grain diameter of 50 µm was used as the raw material. The obtained coatings have the thickness close to 200 µm. It has been shown that the offered method enables to create of non-destructive hydroxylapatite-based coatings on polymer by varying the distance between the polymer target and the gun nozzle of gas- detonation setup. Using the data of Raman and X-ray measurements, it was ascertained that gas-detonation deposition doesn’t change the composition of the deposited material. The SEM investigation testifies that the formed hydroxylapatite-based coatings are porous. EPR studies have shown that there are no paramagnetic defects in the obtained coatings, and the coating itself has a higher radiation hardness as compared to the raw powder.

Keywords:gas-detonation deposition technique, hydroxylapatite, biocompatible coating, Raman scattering, X-ray diffractometry, scanning electron microscopy, electron paramagnetic resonance.
