Properties of Zn based alloys esable for bone fixations

Popis výsledku v původním jazyce

Magnesium and its alloys are considered as the suitable materials for preparation of biodegradable implants for fixation of fractured bones. Generally such materials should be gradually dissolved and absorbed in organism without production of toxic compounds. However, the main problem of these materials is still too high corrosion rate in physiological environment that contains chloride anions. Current research proved that corrosion rate can be decreased in some cases by suitable alloying of magnesium with rare earth elements or zinc. Different magnesium alloys such as AZ, LAE, WE and new alloying system such as Mg-Zn, Mg-Zn-Gd, Mg-Zn-Y with zinc as major constituent have been studied recently. Moreover amorphous ternary Mg-Zn-Ca alloys containing about 50 wt.% of Zn are considered as the promising candidates for biodegradable implants. Zinc is important for many functions in human organism. Its recommended dietary allowance (RDA) is 15 - 40 mg per day. This indicates that Zn-based all
