Characterization 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 کاملDegradation 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 کاملNi-B Coating Production on Magnesium Alloy by Electroless Deposition
The use of magnesium alloys is limited due to their susceptibility to corrosion although they have many attractive physical and mechanical properties. To increase mechanical and corrosion properties of these alloys, many deposition method and coating types are used. Electroless Ni–B coatings have received considerable interest recently due to its unique properties such as cost-effectiveness, th...
متن کاملFormation and Evaluation of Oxidation Behavior of Zirconia- Aluminide Coating on Nickel- Based Alloy
Practical applications of thermal barrier coatings with aluminide bond-coats are limited due to oxide scale spallation of the aluminide coating under applied thermal stresses. Considering the positive effects of oxygen-active elements or their oxides on the high temperature oxidation behavior, in this research zirconia was introduced into an aluminide coating. For this purpose, a Watts type bat...
متن کاملMicro-arc Oxidation (MAO) Coupling Electrophoresis Deposition (EPD) Versus Hydroxyapatite Coating in Periimplantitis: An Experimental Study in Dog
Object: This paper aims to evaluate the influence of dental implants coated with hydroxyapatite (HA) and implants processed by micro-arc oxidation (MAO) coupling electrophoresis deposition (EPD) on experimental peri-implantitis in Beagle dogs. Methods: The thirty-six implants (diameter 3.3 mm & length 11 mm) were equally divided into three groups. Group A was processed with a plasma-sprayed lay...
