Název v původním jazyce

Corrosion and mechanical properties of biodegradable zn-based And mg-based alloys

Popis výsledku v původním jazyce

Zn and Mg- based alloys are promising materials for medical implants because the mechanical characteristics of their alloys are close to human bone and zinc and magnesium are relatively non-toxic. In addition, magnesium is well-known for providing optimum corrosion rates under specific conditions. Therefore, in this paper, the corrosion behaviour of these alloys is compared to that of biodegradable materials. Alloys were prepared by casting without protective atmosphere. The microstructure of prepared alloys was observed by light and scanning electron microscopy (SEM). The mechanical properties of the investigated alloys were determined by Vickers hardness measurements at ambient temperature. The corrosion rates of alloy samples were measured by theirexposure in a solution with similar characteristics to the body fluid. Corrosion rates were calculated of the decrease weight of the exposed samples per exposure time. Corrosion products on the surface were analysed using X-ray diffractio
