Hydroxyapatite ceramics coating on magnesium alloy via a double layered capsule hydrothermal hot-pressing

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...

ELECTRODEPOSITION OF NANO SIZE HYDROXYAPATITE COATING ON TI ALLOY

A film of osteoconductive and biocompatible material on biomedical metallic implants can create bioactivity of the implant and shorten healing time. Hydroxyapatite, that is the most important mineral part of human bone, was coated on Ti6Al4V using cathodic electrode position process. Pulse electrode position technique was used and the effects of different parameters such as potential, duty cycl...

Rapid coating of AZ31 magnesium alloy with calcium deficient hydroxyapatite using microwave energy.

Due to their unique biodegradability, magnesium alloys have been recognized as suitable metallic implant materials for degradable bone implants and bioresorbable cardiovascular stents. However, the extremely high degradation rate of magnesium alloys in physiological environment has restricted its practical application. This paper reports the use of a novel microwave assisted coating technology ...

Ni-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...
