Influence of Concentration of Potassium Hydroxide in Electrolyte on Formation of Hydroxyapatite Coatings on Titanium

Hydroxyapatite coatings were deposited on commercially pure titanium substrates using plasma electrolytic oxidation at various concentrations of potassium hydroxide (i.e., 0.5 M, 1 M, 1.5 M and 2 M) in an electrolyte containing hydroxyapatite. The microstructure, phase composition, morphology and el...

More Information
Summary:Hydroxyapatite coatings were deposited on commercially pure titanium substrates using plasma electrolytic oxidation at various concentrations of potassium hydroxide (i.e., 0.5 M, 1 M, 1.5 M and 2 M) in an electrolyte containing hydroxyapatite. The microstructure, phase composition, morphology and elemental composition of PEO coatings were studied. The electrochemical corrosion behaviour of the hydroxyapatite coatings was investigated in Ringer’s solution. It was shown that corrosion resistance was increased by increasing the concentration of potassium hydroxide.
