IMPROVED MECHANICAL AND IMMERSION CHARACTERISTICS OF...
ABSTRACT
Magnesium-based materials owing to their biodegradable nature are modern materials suitable for orthopaedic
implant applications. Design of such materials with controlled degradation rate coupled with superior mechanical properties is a
niche field of research to meet the ever-increasing demands of the medical community. Development of novel magnesium based
materials with suitable alloying elements and bio-ceramic reinforcements can act as a possible solution to this demand. In the
current study, the influence of addition of 2 vol. % β-tricalcium phosphate (β-TCP) on the mechanical, damping and immersion
characteristics of pure magnesium are studied. The addition of β-TCP enhanced the yield strength and ultimate strength of pure
magnesium without adversely affecting the ductility. Also, Mg 2 vol. % β-TCP composite resulted in ~115 % enhancement in the
damping characteristics compared to pure magnesium. Addition of β-TCP particles also assisted in controlling the corrosion rate
of pure magnesium.
