The main motivation for this study was to improve implant materials. The influence of silver and gold on the structure and mechanical properties of Mg-Nd-Zr alloy was studied. In the work, quantitative and qualitative evaluation of the structural components of magnesium alloy with noble metal additives was performed. The research methods used were investigation of the mechanical properties and observation of micro- and macrostructures. The results showed that modification of magnesium alloy with Ag and Au contributes to the formation of spherical intermetallics of smaller size groups, which become additional centers of crystallization and grind the cast structure. The best composition from additional alloying with silver and gold was determined. Their positive effect on the strength and ductility properties of the metal was established. Preclinical and clinical testing was performed and the prospects for noble metal modification of bioabsorbable magnesium alloy for implant production usage were shown.
本研究的主要动机是改进植入材料。研究了银和金对Mg-Nd-Zr合金结构和力学性能的影响。在这项工作中，对添加贵金属的镁合金结构成分进行了定量和定性评估。所采用的研究方法是力学性能研究以及微观和宏观结构观察。结果表明，用银和金对镁合金进行改性有助于形成尺寸较小的球状金属间化合物，这些化合物成为额外的结晶中心并细化铸造组织。确定了银和金额外合金化的最佳成分。证实了它们对金属强度和延展性性能的积极影响。进行了临床前和临床试验，并展示了生物可吸收镁合金用于植入物生产的贵金属改性前景。
