Raman scattering spectroscopy to estimate surface of VT6 titanium alloys

The results of Raman scattering spectroscopy studies of the surface of implant samples with different types of coatings are presented. Samples based on the VT6 titanium alloy manufactured by the selective laser sintering technique with different coatings (without coatings, with a calcium hydroxyapatite coating, with a combined coating of calcium hydroxyapatite with an antimicrobial drug coating applied on top, and samples with a chitosan-containing coating) were studied. Spectral differences between surfaces of VT6 titanium-based implant samples with different types of coatings are found. The findings will allow studying the dynamics of resorption of these coatings by Raman scattering spectroscopy in preclinical studies in animals.
