Abstract

Magnesium MMC is preferred in applications requiring high-quality materials and has replaced monolithic materials. Bio-implants traditionally used are titanium, steel, and nickel-titanium alloys, however, their removal necessitates surgery, which is costly and painful. While biodegradable 3D-printed implants are effective and eliminate the need for a second surgery, they remain expensive. After several studies to solve this issue, the development of biodegradable implants is considered. Magnesium possesses good biodegradable properties. An investigation is carried out on magnesium alloys, which are more affordable and have better qualities. Although magnesium possesses biodegradable properties it corrodes rapidly in the body’s environment. The need of the hour is to have a composite that degrades gradually. A magnesium-based MMC is efficient in securely and steadily degrading, eliminating the necessity for secondary surgery. The present research focuses on magnesium alloy with tricalcium phosphate as reinforcement and a stir-casting technique. The percentage of reinforcements is 0,5,10,15 of wt%. A hardness and corrosion test were performed. The results show that the corrosion rate of AZ31B+5wt% Ca3(PO4)2, AZ31B+10wt% Ca3(PO4)2, AZ31B+15wt% Ca3(PO4)2 was decreased by 48.58%, 39.17% and 16.94% respectively when compared with pure magnesium. The Vickers microhardness test result shows that the hardness values of AZ31B+0wt%Ca3(PO4)2, AZ31B+5wt%Ca3(PO4)2, AZ31B+10wt% Ca3(PO4)2, AZ31B+15wt% Ca3(PO4)2 are 96.375HV, 62.725HV, 62.025HV and 66.950HV respectively
