Abstract
Investigations of wollastonite biocoatings produced by microarc oxidation method on the Ti and Ti40Nb substrate were presented. There were discovered relationships of coating properties on the microarc oxidation parameters. A variation of the process parameters allowed producing wollastonite-calcium phosphate coatings with a plate-like structure with the thickness of 25-30 μm, roughness of 2.5-5.0 μm and enhanced strength properties. The biocoatings on the Ti and Ti40Nb do not exert toxic effect on the morphofunctional status of human prenatal stromal cells in vitro. A high viability and mobility of the cell culture at the coating-cell interface was detected. Furthermore, the wollastonite-calcium phosphate coating on the Ti40Nb alloy promoted osteogenic potential of fibroblast-like adherent cells (by alkaline phosphatase).
