| Abstract Scope |
The combination of bone-like mechanical properties and biodegradability positions magnesium and its alloys as promising materials for resorbable bio-implants. However, their use is limited by rapid corrosion and low bioactivity in biological environments. Hydroxyapatite (HA), a ceramic similar to bone mineral, is widely used in bone repair for its excellent biocompatibility and ability to promote bone growth. Incorporating HA into Mg alloys improves biocorrosion resistance, but current fabrication methods are time-consuming, costly, and pose safety risks. In the previous study, single step extrusion of AZ31B-HA composite rods using SolidStir®-Extrusion was demonstrated resulting in uniform distribution of HA throughout the microstructure while reducing risks and significantly shortening processing time. Here, we extend the research to analyze the corrosion behavior of the extrudates due to the presence of HA in the matrix. Additionally, the use of SolidStir®-AM, a solid-state based 3D printing method for producing customized, near-net-shape biodegradable implants will be discussed. |
