Abstract

Magnesium alloy in biomedical applications is a choice for implant materials because of its biocompatibility, bioactive, and biodegradability. The addition of lithium in magnesium could improve the mechanical properties of magnesium and change its crystal structure from hexagonal close-packed (HCP) to body-centered cubic (BCC), and the addition of aluminum would improve its hardness and corrosion properties. However, lithium has a complex effect on the human body as the cause of calcium homeostasis, and excess aluminum content on the human body can cause nerve toxicity in the human body. The addition of lithium and aluminum as an alloy of magnesium in this research is only limited to 14wt% lithium and 1wt% aluminum (LA141). The objective of this research is to understand the compatibilities of LA141 properties as biodegradable biomaterials. Homogenization heat treatment at temperature 350°C had been done before characterization with the optical microscope. To investigate the properties of LA141, immersion and polarization test in Simulated Body Fluid (SBF) for corrosion properties and hardness test and tensile test for mechanical properties.
