Magnesium Alloys have the potential to be applied in the various fields of applications including biomaterials. Magnesium Alloys are an interesting alloy due to its high strength to density ratio. They have been proposed as a biodegradable implant material due to its friendly effect to human body compared to another alloy. Besides its good biodegradable properties, it has a disadvantage of low hardness and corrosion properties. In order to overcome this, it has been combined with other metals such as Zinc (Zn) or Copper (Cu). To increase mechanical properties, we used Carbon Nanotubes (CNT) as reinforcement. Magnesium-Zinc (Mg-xZn) CNTs composites with several compositions was prepared by using powder metallurgy and sintered in the presence of flowing Argon (Ar) gas in tube furnace. Mg-Zn Alloy with the composition of 4% and 6% of Zn and the variation of CNTs at 0.1%, 0.3 %, and 0.5% was also prepared. Hardness testing by using microvickers showed that CNTs can increase the alloy hardness which the maximum hardness is 53.6 HV. The corrosion rates as low as 175.5 mpy exhibited for the Mg-Alloy with the composition of Mg-4-Zn with 0.1 wt.% of CNTs

Powder Metallurgy Route

Magnesium is a promising lightweight metal required in many industries such as automobile, aerospace, electronics, etc. It is also a biodegradable material, which eliminates the secondary removal procedure of the implant. Furthermore, its mechanical properties are similar to the mechanical properties of human bone.  In this research, eggshells were used as an environmentally friendly composite reinforcement material in the Mg-2.5Zn-1Mn matrix. Composites were prepared using the powder metallurgy route.  The effect of eggshells on the morphology, mechanical, and corrosion behaviour of Mg-2.5Zn-1Mn alloy was investigated. The results revealed an enhancement in grain refining ability and mechanical properties of Mg-2.5Zn-1Mn with eggshell additives. The corrosion behaviour improved at a higher percentage of eggshells (10%).
