Low-temperature bioresorbable composite material magnesium-hydroxyapatit

摘要

This work is focused on the development of 《Magnesium (Mg) - Hydroxyapatite (HA)" composite for bioresorbable implant obtained by spark plasma sintering method (SPS). The structural-phase state of the samples was studied using the X-ray phase analysis method and scanning microscopy (SEM). It is essential to understand the mechanical behaviour of these materials: compressive strength were determined for material characterization. The obtained composite materials were investigated in the solution simulating the extracellular fluid of the human body (SBF) and NaCl solution, and there was shown the allocation of ions of calcium and magnesium and the formation of calcium-phosphate layer (CFL) on the surface of sintered samples and demonstrated. It follow that the material Mg-HA has a biocompatibility in vitro.
