Биоактивные композиты для восстановления костных тканей на основе железа

Abstract

In the present study, we performed studies of the microstructure and phase composition of metalceramic composites from Fe 90 wt. % - Cu 10 wt. % powder and hydroxyapatite (Fe-Cu-HA). The composite material was obtained using additive manufacturing based on the 3D printing method with different content of powder (40, 45 and 50 %) and polymer parts (60, 55 and 50 %). It is shown that varying the proportion of Fe-Cu-HA powder does not significantly affect the elemental and phase compositions of the material. X-ray phase analysis showed the presence of three phases in the material: alpha iron, copper and hydroxyapatite. It is shown in the experiment that an increase in the polymer component of the composite leads to an increase in the defectiveness of the structure, as well as an increase in microstresses
