“…Calcium phosphates represent a big promise for they can be used as biomedical coatings on magnesium substrates [16]. The literature of the last couple of years enumerates several methods for hydroxyapatite deposition on magnesium/Mg alloys: sol-gel coating [17], electrodeposition [18,19], a cathodic arc PVD technique [20], chemical solution deposition [21][22][23], dipping and immersion [24,25], cold spray deposition [26], plasma electrolytic oxidation [27,28], and a transonic particle acceleration deposition process [29]. However, the available literature presenting hydroxyapatite coatings deposition with atmospheric plasma spraying on magnesium alloy substrates is incomplete.…”

“…The influence of magnetic fields in orientating the crystals during the coating formation was investigated, along with the types of phases present. The technique produced coatings composed of DCPD and HAP phases, the coatings were found to enhance corrosion resistance and significantly reduced the degradation rate of the substrate [66]. For example, Figure 4 presents a set of representative potential-dynamic polarization curves showing the improvement in corrosion resistance of an Mg substrate after receiving a DCPD coating.…”

Historically, cobalt-chromium, stainless steel and titanium alloys have been the main principal materials used in a variety of medical procedures for load-bearing implants in the body. Magnesium and magnesium-based alloys have the potential to be used as short-term structural support during the healing process of damaged hard tissues and diseased bone. Unlike traditional biologically compatible metals, which are not biologically degradable, magnesium based alloys offer both biological degradability and biological absorbability. Despite the many advantages offered by magnesium, its rapid degradation rate in the highly aggressive and corrosive body fluid environment has severely limited its present day medical application. This article reviews the chemical immersion technique for producing calcium phosphate coatings on magnesium substrates for slowing down the degradation rate while maintaining the biological compatibility and absorbability.

“…The involved dipping a Mg substrate into an aqueous solution containing Ca (NO 3 ) 2 .4H 2 O and Na 2 HPO 4 .12H 2 O. Deposition of both DCPD and HAP phases under the influence of magnetic fields lead to crystal orientation during the formation of the phases. The technique also produced coatings with enhanced corrosion resistance, wh ich in turn reduced the degradation rate [195]. In an alternative method, Song et al used an electro-deposition technique to produce three types of coating namely; DCPD, HAP and fluorapatite (FHA ).…”

The involved dipping a Mg substrate into an aqueous solution containing Ca (NO 3 ) 2 .4H 2 O and Na 2 HPO 4 .12H 2 O. Deposition of both DCPD and HAP phases under the influence of magnetic fields lead to crystal orientation during the formation of the phases.…”

Magnesium and magnesium based alloys are lightweight metallic materials that are extremely biocompatib le and have similar mechanical properties to natural bone. These materials have the potential to function as an osteoconductive and biodegradable substitute in load bearing applicat ions in the field of hard t issue engineering. However, the effects of corrosion and degradation in the physiological environ ment of the body has prevented their wide spread applicat ion to date. The aim o f this review is to examine the properties, chemical stability, degradation in situ and methods of improving the corrosion resistance of magnesium and its alloys for potential application in the orthopaedic field. To be an effective imp lant, the surface and sub-surface properties of the material needs to be carefully selected so that the degradation kinetics of the implant can be efficiently controlled. Several surface modification techniques are presented and their effectiveness in reducing the corrosion rate and methods of controlling the degradation period are discussed. Ideally, balancing the gradual loss of material and mechanical strength during degradation, with the increasing strength and stability of the newly forming bone tissue is the ultimate goal. If this goal can be achieved, then orthopaedic implants manufactured fro m magnesium based alloys have the potential to deliver successful clinical outcomes without the need for revision surgery.
