| Description
| - Magnesium and its alloys are suitable materials for the production of biodegradable implants applied for example for fixation of fractured bones. The mechanical properties of these alloys exceed polymer materials and their values are close to the mechanical properties of bone. The biodegradable materials should be dissolved in the body after some time to produce non-toxic products. Magnesium is not toxic to the organism and plays a very important role in many biochemical reactions. However it is characterized by high corrosion rates in many cases. Corrosion resistance of magnesium alloys is influenced by the content of impurities, alloying elements and aggressive environments. Currently, research focuses on magnesium alloys doped by rare earth elements (RE). RE are able to slow down the corrosion process and affect the mechanical properties of alloys depending on concentration and combination of them. In present work, the corrosion behaviour of magnesium and its alloys in the as-cast state in 9g/l NaCl solution were evaluated. Moreover some mechanical properties were evaluated. Mg-Gd binary and Mg-Gd-Y ternary alloys were prepared by vacuum induction melting. All measured properties were compared with AZ91 high purity alloy. Suitable properties were mainly achieved in the case of binary alloys containing lower amounts of gadolinium.
