Özet
Bio-metallic CoCrMo alloys were coated with hydroxyapatite layers by electrodeposition to improve biocompatibility. Surface morphology was analyzed by scanning electron microscopy. Chemical composition was investigated by FTIR. In vitro corrosion performance was examined by electrochemical impedance spectroscopy and Tafel measurements in a simulated body fluid. Corrosion performance of the coatings deposited at various pH values was investigated using Zview and COMSOL computer modeling programs. Both programs successfully modeled EIS results. Increasing the electrolyte pH improved corrosion performance of the biocompatible coatings. Electrolyte pH influenced corrosion properties, chemical composition, and surface morphology of the coatings. (C) 2015 Elsevier B.V. All rights reserved.
