UDK 669.721.5
One of the most promising materials for the production of implants are Mg−Zr−Nd alloys. They are bioinert, biocompatible and have the biodegradation ability, but their use in osteosynthesis is limited due to their insufficient mechanical properties after prolonged exposure to the internal environment of the body. The effect of the main alloying elements (Zr, Nd, Zn) on the mechanical properties of the Mg–Zr–Nd alloy was studied using the experimental design. Optimization of the chemical composition of the alloy increased the tensile strength (σB ) and elongation at break (δ). Animal experiments showed the absence of the toxicological effect of the degradation products of the developed magnesium alloy on a living organism. The study of the processes of bone regeneration of the studied animals gave a positive result. |
