Abstract

A method that does not require an applied electrical signal or cladding technique is exploited to generate a hydroxyapatite (HA) containing conversion coating on Mg. The coating contained HA+Mg(OH)2 and was shown to control dissolution of Mg. Electrochemical and immersion tests were used to examine the biodegradation performance of coated Mg in Minimum Essential Medium (MEM) via exposure in a CO2 incubator at 37°C. The results herein reveal that the HA-Mg(OH)2 coatings significantly retard the biodegradation rate of the substrate.
