A brief overview of HA on the mechanical behavior of MMCs

Magnesium-based materials are currently the most effective material employed in biomedical, aerospace, and automotive applications due to their high strength-to-weight ratio, low density, and high damping capacity. Confining to poor strength, wear, and corrosion behavior of Mg materials attributed to the formation of metal matrix composite with suitable usage of reinforcing element. The reinforcing agents are pertaining to act as a beneficial element in order to illustrate the final characteristics of the composites and help in controlling the porosity (%) of the composite. The controlling of porosity (%) is the signification of the addition of an optimum amount of reinforcement in the matrix material. Keeping the degradation rate of Mg material and suitability of an element in non-load applications, Hydroxyapatite (HA) is the most suitable reinforcing element, providing the pathway to rapid recovery of bone tissue to heal and improving the overall mechanical and corrosion resistance behavior of the Mg-based materials. For the preparation of MMCs (metal matrix composites), the Powder metallurgy approach is observed to be beneficial, allowing uniform dispersion of the reinforcing elements in the composites, requiring no machining, and complex shapes can be easily fabricated. The current study paved a way for the different aspects of the hydroxyapatite material in influencing the overall behavior of the composite including the mechanical and corrosion behavior of the composites.
