Experimental analysis of mechanical characteristics of fabricated biodegradable magnesium hydroxyapatite MMCs for biomedical purposes

In regards to materials, orthopaedic implants can be composed of magnesium alloys. They are absolutely biocompatible and have characteristics that comparable to the individuals of authentic bone. Their degradable ability indicates that they do not have to be removed out after the wound has healed completely. Magnesium, however, corrodes too quickly in the body's environment, so matrix composites can be a solution for controlling its corrosion rate and improving its mechanical qualities. In the present study, a stir casting technique was used for developing Mg HAP MMCs. As a reinforcing material, HAP powder has been utilised. After casting, composites were cut into required form samples for mechanical testing. In the final stage, tensile and compression tests were used. As a result of adding HAP powder, UTS, total tensile strain and compressive strength are significantly reduced. The elongation reduced, yield strength and young modulus shows distinct behaviours but compressive yield strength increased.
