Abstract:
Bioactive ceramic coatings based on calcium phosphate (Ca-P) are commonly used to modify implant material surfaces and to create new surfaces with completely distinct characteristics from the substrate. Several coating methods are often used to coat metal implants. In the present study, an attempt was made to develop a Ca-P coating biomimetically on magnesium alloy substrates (AZ31) by immersing them in a supersaturated calcification solution (SCS). The Ca-P deposit thus formed has been then evaluated according to the physicochemical and mechanical characteristics. Calcium phosphate deposits (Ca-P) were considered using an optical microscope (OM), scanning electron microscope (SEM), X-ray dispersive analysis (EDX), and X-ray diffraction (XRD). Whereas, the Ca-P deposits adhesive nature on untreated and treated surfaces was determined by scratch analysis. The biomimetic deposition of calcium phosphate (Ca-P) is an easy and cost-effective method that preserves the substrate's mechanical properties and provides good adherence.
