Structural and morphological properties of hydroxylapatite coatings obtained by gas-detonation deposition on polymer and titanium substrates
V. Lashkaryov Institute of Semiconductor Physics, NAS of Ukraine, 41, prosp. Nauky, 03680 Kyiv, Ukraine 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.
