The elasticity of calcium phosphate MAO coatings containing different concentrations of chitosan

Abstract

Calcium-phosphate coatings were formed on the commercially pure titanium by the method of microarc oxidation (MAO) from the electrolyte, which additionally contains 2.5-15wt.% solution of chitosan. The surface morphology, wettability and elasticity of the formed coatings were investigated. It is shown that the addition of chitosan to the electrolyte composition increases porosity and elasticity of the coatings.
