Growth and corrosion behaviour of amorphous micrometre scale calcium phosphate coatings on magnesium substrates

Abstract
Amorphous calcium phosphate (ACP) coatings were formed on magnesium substrates via a straightforward electrochemical technique in order to improve the corrosion resistance of the substrates. X-ray diffraction spectroscopy and microscopy techniques were used to investigate the size, morphology, composition and structure of the ACP coatings. Analysis of the ACP coatings revealed the presence of micrometre scale fissures and tubular structures. Despite the presence of these features, the coatings were still capable of significantly reducing the corrosion rate in both PBS and Ringer’s solutions. Ringer’s solution was found to be the most aggressive towards Mg substrates with a corrosion rate of 3.828 mm/yr. However, after electrochemical treatment, the corrosion rate of substrates coated with ACP was reduced to 0.557 mm/yr. The significant improvement in corrosion resistance is a first step in controlling the corrosion rate of biodegradable Mg substrates for potential use in hard tissue applications.
