Orthopedic Applications

Magnesium alloys have the potential as a biodegradable material for orthopedic applications. However, severely corrosion in a physiological environment limits the clinical application of Mg alloys. Hydroxyapatite is the main composition of natural bone, it has excellent bioactivity and osteoconductivity. In this paper, the samples of AZ31 were ultrasonically cleaned using distilled water, and then the coating was formed on the surfaces of the samples by biomimetic process. The samples were subsequently immersed in the simulated body fluid (SBF) for the degradation test. The coatings were characterized by XRD, EDS and SEM. The results showed that hydroxyapatite (HA) coating was formed on the surface of AZ31 after 24h by biomimetic process; the HA coating greatly decreased the corrosion rate of AZ31 substrate; the degradation rate of samples can be controlled by closely adjusting the hydroxyapatite coating.

Plasma Sprayed

The Success of Hydroxyapatite-Coated Acetabular Components Has Not Been Consistent. Plasma-Sprayed Hydroxyapatite Coatings Work Well on Nonporous Substrates but Do Not Coat the Inner Surfaces of Open-Porous Substrates. Solution Deposition Can Generate Consistent Bioceramic Coats on Porous Surfaces that More Closely Mimic the Trabecular Pattern and Biochemistry at the Bone Interface. we Compared Bone Response to the Following Implants: Porous-Coated Ti6al4v Cylinders with 1 of 3 Treatments: Plasma Sprayed with Hydroxyapatite (HA), Coated with a Solution-Deposited Biomimetic Apatite Coating (BA), and Untreated (Control). Bilateral Femurs in 36 Rabbits Were Implanted with One of the above Implants. Bone Ingrowth for HA and BA Surfaces Was Significantly Higher than that for Control Surfaces. No Fragmentation or Debris Production Was Evident in the Apatite Coat of the BA Group. A Biomimetic Coat of Solution-Deposited Apatite May Be Resistant to Coating Delamination and Particle Generation.

Bone-like apatite coatings were prepared using a biomimetic method in a simulated body fluid (SBF). The effect of initial pH values on the surface morphology of biomimetic apatite coating was studied. The coatings were characterized using X-ray diffraction and environmental scanning electron microscope. It was revealed that the morphology of the biomimetic apatite coating could be tailored by manipulating the initial pH of the SBF solution.
