  • Structural, mechanical and cytotoxicity characterization of as-cast biodegradable Zn-xMg (x = 0.8-8.3 %) alloys = Strukturne, mehanske in citotoksične lastnosti biorazgradljive Zn-xMg (x = 0,8-8,3 %) zlitine v litem stanju
    Kubásek, Jiří ...
    In the present work, the structural, tensile, compressive and bending mechanical properties as well as the cytotoxicity of the Zn-Mg biodegradable alloys containing mass fractions from 0 % up to 8.3 ... % Mg were studied. It was found that the maximum tensile and compressive strengths of 170 MPa and 320 MPa, respectively, were obtained for the Zn-0.8Mg alloy. This alloy also showed the highest tensile elongation of 2 %. Mechanical properties were discussed in relation to the various structural features of the alloys. The structure of the strongest Zn-0.8Mg alloy was composed of a fine mixture of a-Zn dendrites and a-Zn + Mg2Zn11 eutectics. The cytotoxicity was evaluated with an indirect contact assay using human osteosarcoma cells (U-2 OS). The cytotoxicity of the Zn-0.8Mg alloy extract was low and only slightly higher than in the case of the pure-Mg extract.
