Preparation and Basic Characterization of Novel Zinc-based Alloys for Intracorporeal Implants

Zinc is considered to be a suitable element for the preparation of bioresorbable materials that can gradually degrade in human body without production toxic compounds and undesirable hydrogen gas. Zn characterized by much lower corrosion rate saline compared magnesium-zinc its alloys. Therefore, this work we investigate Zn-0.4Mg-0.4Ca-xMn alloys with 0, 0.2, 0.4, 0.6 0.8 1.1 wt. % Mn. The elements Mg, Ca Mn were selected improve mechanical properties biocompatibility pure Zn. microstructure was studied optical light microscope SEM equipped EDX analyzer. measuring microhardness using Vickers method. results experimental part show trend improvement increasing content. immersion tests carried out Hank's solution after 6 months material retained shape integrity.
