Properties of biodegradable alloys usable for medical purposes
Original language description
Magnesium alloys are promising materials for production of biodegradable implants that may be used for fixation of fractured bones. Magnesium itself is an essential element that play important roles in many biological processes. However, some common alloying elements of magnesium alloys such as aluminium or copper may cause health problems for organism. A major problem is the high corrosion rate of magnesium and its alloys in physiological environment that contains chloride anions. Currently, the research focuses on alloys doped by rare earth elements (RE) and zinc. All these elements may slow down the corrosion process and affect the mechanical properties of alloys. This work was dealing with the study of Mg-Gd binary alloy and Mg-Gd-Y, Mg-Gd-Zn ternary alloys that were prepared from pure metals by melting in induction furnace. Various alloy compositions were tested. Corrosion behaviours in 9M NaCl saline environments (exposure tests, potentiodynamic measurements) were studied on allo
