Influence of processing on the microstructure and the mechanical properties of Zn/HA8 wt.% biodegradable composite

Popis výsledku v původním jazyce

Zinc-based materials show large potential to become biodegradable materials with ideal corrosion behavior in the body environment. In this study, a zinc composite containing 8 wt. % of hydroxyapatite (HA) was prepared by spark plasma sintering (SPS) and characterized from a point of view of the microstructural and mechanical prop-erties. The influence of pre-processing (milling) of the powders on the microstructure after the sintering was stud-ied. The materials prepared by the milling and subsequent sintering showed insufficient cohesion due to the wrap-ping of Zn by HA particles and possible oxidation of zinc particles. Compressive and flexural tests of sintered materials prepared without any pre-processing confirmed the role of hydroxyapatite as a defect in the Zn/HA8_SPS structure. The results of the hardness measurement suggest that the HA does not affect the behavior of the zinc matrix.
