Effect 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 کاملCharacterization of hydroxyapatite containing micro-arc oxidation coating on ZK60 magnesium alloy
INTRODUCTION: Magnesium alloys are attractive as a class of biodegradable metallic materials. However, too fast degradation is an obstacle to their clinical applications. Recently, micro-arc oxidation (MAO) coatings were applied on biodegradable magnesium alloys to delay their degradation. In vivo studies showed that the protective ability of the MAO coating should be further improved [1]. Seal...
متن کاملPreparation and Characterization of Aminated Hydroxyethyl Cellulose-Induced Biomimetic Hydroxyapatite Coatings on the AZ31 Magnesium Alloy
The purpose of this work is to improve the cytocompatibility and corrosion resistance of magnesium alloy in the hope of preparing a biodegradable medical material. The aminated hydroxyethyl cellulose-induced biomimetic hydroxyapatite coating was successfully prepared on AZ31 magnesium alloy surface with a sol-gel spin coating method and biomimetic mineralization. Potentiodynamic polarization te...
متن کاملPreparation and Characterization of Hydroxyapatite Coating on AZ31 Mg Alloy for Implant Applications
Magnesium alloys as biodegradable metal implants in orthopaedic research received a lot of interest in recent years. They have attractive biological properties including being essential to human metabolism, biocompatibility, and biodegradability. However, magnesium can corrode too rapidly in the high-chloride environment of the physiological system, loosing mechanical integrity before the tissu...
متن کاملInfluence of KMnO4 Concentrationon Infrared Emissivity of Coatings Formed on TC4 Alloys by Micro-Arc Oxidation
Ceramic coatings with high emissivity were fabricated on TC4 alloys by micro-arc oxidation technique (MAO) in mixed silicate and phosphate electrolytes with varying KMnO₄ addition. The microstructure, phase and chemical composition were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS), and the infrared emissivity of the MAO...
