| Abstract Scope |
Magnesium (Mg) alloys are promising candidates for bio-medical applications owing to their desirable mechanical properties and interactions in biological system. However, their clinical application is limited due to the degradation rate being faster than healing. Hydroxyapatite (HA) is a potential reinforcement for increasing the biodegradation resistance of Mg alloys. Additive manufacturing (AM) of Mg-based materials is of growing interest due to enabling design capabilities not achievable by traditional manufacturing methods.
In this study, two types of blending and milling technologies were selected to incorporate HA into WE43 powder. It aims to determine an optimal mixing process to blend HA and WE43 powders for the AM of Mg-base composites in order to retard its degradation. The effects of the various types of powders generated by these mixing processes are investigated in terms of their effects on the AM processes, degradation behavior, microstructure, and mechanical properties of the HA reinforced WE43 composite. |
