Influence of Nanoparticles Deposition Conditions on the Microarc Coatings Properties

Abstract

The surface charge of biomaterials significantly contributes to such processes as protein adsorption or biofilm formation and consequently osseointegration bone tissue and implant. There are a set of methods to create a charge on dielectric biomaterials surface. One of the perspective methods of materials electrization is an introduction of the nanoparticles with appropriate biomedical properties into biomaterial. Boehmite AlO(OH) nanoparticles is perspective for the biomaterials surface modification due to its high surface area and positive charge. In this work, the investigations of microarc calcium phosphate biocoatings modified by boehmite nanoparticles on the Ti substrate were presented. A variation of the nanoparticles deposition parameters allowed producing calcium phosphate coatings with different morphology and boehmite nanoparticles size distribution. The investigations of the modified coatings by the transmission and scanning electron microscopy methods are presented in the work.
