Interaction between Dusty Shock Waves and Three-Dimensional Scaffolds of Carbon Nanocomposites upon the Deposition of Biocompatible Coatings

Resumo

The interaction between shock waves (velocity D0 ≈ 2–2.5 km s⁻¹ and maximum pressure p_max ≈ 3.1–3.8 MPa) containing finely dispersed hydroxyapatite particles (with mean diameters of d_p ≈ 70 nm and 100 μm) and substrates of carbon nanostructured composites that are a periodic three-dimensional scaffold is investigated experimentally. Study of these processes is important for the development of nonconventional osteoconductive and biocompatible materials with properties of osteoinduction. Features of the interaction between dusty shock waves and these substrates are established on the basis of complex experimental studies. Optimum conditions and ways of forming high-adhesion coatings on carbon composites are determined.
