Degradation and biological properties of Ca-P contained micro-arc oxidation self-sealing coating on pure magnesium for bone fixation
Poor corrosion resistance is one of the main disadvantages for biodegradable magnesium-based metals, especially applied for bone fixation, where there is a high demand of bio-mechanical strength and stability. Surface coating has been proved as an effective method to control the in vivo degradation. In this study a Ca-P self-sealing micro-arc oxidation (MAO) coating was studied to verify its ef...
متن کاملImproved biological performance of magnesium by micro-arc oxidation
Magnesium and its alloys have recently been used in the development of lightweight, biodegradable implant materials. However, the corrosion properties of magnesium limit its clinical application. The purpose of this study was to comprehensively evaluate the degradation behavior and biomechanical properties of magnesium materials treated with micro-arc oxidation (MAO), which is a new promising s...
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 کاملSynthesis and properties of hydroxyapatite-containing porous titania coating on ultrafine-grained titanium by micro-arc oxidation.
Equal channel angular pressing results in ultrafine-grained (approximately 200-500 nm) Ti with superior mechanical properties without harmful alloying elements, which benefits medical implants. To further improve the bioactivity of Ti surfaces, Ca/P-containing porous titania coatings were prepared on ultrafine-grained and coarse-grained Ti by micro-arc oxidation (MAO). The phase identification,...
متن کاملMicro Computed Tomography Analysis of Magnesium Screw Degradation & Bone Regeneration
INTRODUCTION 6.3 million cases of bone trauma happen each year in the US alone [1]. In a majority of these cases, permanent fixation implants using titanium plates and screws are used as a remedy, but they do have their drawbacks. Some of these disadvantages include bone wear and degradation, resulting in the implant to become loose. They also present a prime site for possible infection [2]. An...
