Micro- and Macroporosity of Three-Dimensional Capillary-Porous Composite Coatings

We have analyzed the surface of a plasma three-dimensional capillary-porous (TDCP) Ti coating with an additional bioactive hydroxyapatite coating formed by microplasma oxidation (MPO). Scanning electron microscopy (SEM) was used to analyze the open porosity of these composite coatings. The surface o...

More Information
Summary:We have analyzed the surface of a plasma three-dimensional capillary-porous (TDCP) Ti coating with an additional bioactive hydroxyapatite coating formed by microplasma oxidation (MPO). Scanning electron microscopy (SEM) was used to analyze the open porosity of these composite coatings. The surface of the TDCP Ti coating consists of ridges and valleys. The main porosity of the TDCP Ti coating is concentrated within the volume of valleys and reaches 43%. The presence of macro- and micropores 0.08–600 μm in size makes TDCP Ti coatings promising for using in a variety of fields, including as the surface coatings of intraosseous implants.
