Characterization of Plasma Sprayed Hydroxyapatite Coatings on AISI 316L SS and Titanium Substrate and their Corrosion Behavior in Simulated Body Fluid
In order to increase the bone bioactivity of metallic implants, hydroxyapatite (HA: Ca10(PO4)2(OH)6) is often coated on their surface so that real bond with surrounding bone tissue can be formed. In present study, HA coatings were deposited on AISI 316L SS and titanium using shrouded plasma spray process. The coated specimens were subjected to X-ray diffraction (XRD) analysis, field emission sc...
متن کاملFormation and characteristics of the apatite layer on plasma-sprayed hydroxyapatite coatings in simulated body fluid.
Plasma-sprayed hydroxyapatite (HA) coatings were incubated in simulated body fluids (SBFs) for different periods of time to investigate the nucleation and growth of apatite on their surface. The layer that formed was recognized as having similarities to bone apatite because it is poorly crystallized, non-stoichiometric or calcium deficient, and contains carbonate and magnesium. Scanning electro...
متن کاملEffect of TiO2 nano-particles on corrosion behavior of Co-Cr alloy coatings in simulated body fluid
Co-Cr and Co-Cr/nano-TiO2 coatings were electrodeposited from Cr(III) based baths. The effect of TiO2 nano-particles incorporation on the morphology, structure, crystallite size, and preferred orientation was studied. Corrosion behavior of the composite coating was also investigated by means of polarization and electrochemical impedance spectroscopy techniques in Hanks’ si...
متن کاملEffect of coating time on the corrosion behavior of ceramic coatings containing hydroxyapatite nanoparticles by plasma electrolytic oxidation method on AZ31 Mg alloy in simulated body fluid
In this study, the effect of coating time on the microstructure and corrosion behavior of AZ31 Mg alloy coated by plasma electrolytic oxidation (PEO) method has been investigated. For this purpose, phosphate-based electrolyte containing hydroxyapatite nanoparticles was used at different times of 5, 10 and 15 minutes. The surface properties and chemical composition of the coatings were investiga...
متن کاملEFFECT OF CURRENT DENSITY ON MICROSTRUCTURE AND CORROSION BEHAVIOR OF PURE COBALT COATINGS OBTAINED
Pure cobalt coatings were electrodeposited on copper substrate by means of direct electric current in a chloride solution at different current densities in the range of 10-70 mA cm -2 . The surface morphology and microstructure were investigated via X-ray diffraction analysis and scanning electron microscopy. Corrosion behavior of cobalt coatings was also studied in a 3.5 wt% NaCl soluti...
