Investigation on the Controlled Degradation and Invitro Mineralization of Carbon Nanotube Reinforced AZ31 Nanocomposite in Simulated Body Fluid

다국어 초록 (Multilingual Abstract)

Magnesium (Mg) based implant materials are believed to be the perfect candidates for biomedical applications due to theirversatile properties. However, regulating their corrosion/degradation rate in the biological surroundings is still a noteworthytask. Suitable strategies to overcome this task is to wisely select alloy elements with improved corrosion resistanceand mechanical characteristics. An attempt has been made to enhance the corrosion and biocompatibility performance ofmagnesium alloy AZ31 containing carbon nanotubes (CNTs) as reinforcement and evaluate its degradation and invitromineralization performance in physiological medium. Corrosion behavior of AZ31 alloy with CNTs reinforcement wasinvestigated using electrochemical methods, weight loss, and hydrogen evolution in SBF during short and long-term periods.
The obtained results revealed that the corrosion resistance of AZ31 alloy enhanced significantly due to the incorporationof CNTs. Hydrogen evolution test and weight loss tests revealed that the presence of CNTs improves the stability of theMg(OH)2 and efficiently regulate the degradation behavior in SBF. Surface characterization after immersion in SBF revealedthe rapid formation of bone-like apatite layer on the surface, validated a good bioactivity of the AZ31 nanocomposite samples.
