Title: Formation and properties of biocoatings based on wollastonite and calcium phosphates

Wollastonite-calcium phosphate coatings were produced on titanium substrates by micro-arc oxidation method. There presented the study of influence of oxidation voltage, process duration and pulse duration on properties of the coatings such as thickness, surface morphology and surface roughness. The morphology and phase composition of the coatings were studied by scanning electron microscopy and X-ray diffraction methods. It was found that biocoatings with large amount of wollastonite particles were deposited under minimum oxidation voltage of 130–150 V. The structural elements with a spherical or plate-like shape were formed on the coating surface depending on micro-arc oxidation parameters.
