【 摘 要 】

Biodegradable materials represent a new class of biocompatible materials with applications in many medical cases where thesupport must be provided only for a certain period. In this article obtaining of ZnMgY alloy is presented along with some basiccharacteristic investigations like chemical composition (energy dispersive spectroscopy – EDS), microstructure (optical microscopy – OM and scanning and electron microscopy – SEM), immersion behavior in 10xDPBS (Dulbecco Phosphate Buffer Saline)solution (mass loss and surface degradation), electro-corrosion behavior (potentiostat with a three electrodes cell) and micro-hardnessof the experimental alloy compared to cast Zn and ZnMg materials. The results present an improvement of micro-hardness of Znby alloying with Mg and Y and a modification of corrosion resistance.
