Abstract
Titanium and its alloy has been become the most common and favorite material for biomedical implant, especially Ti-6Al-4V. It provides excellent bio-compatibility, corrosion resistance and high mechanical strength. Ti-6Al-4V also has high strength to weight ratio, which is one of the most considered parameters in selecting implant materials. However, due to its potential of cytotoxicity and osseointegration issue, this alloy requires additional surface treatment to prevent direct contact to cellular tissues. One of the solution to modify the surface is by coating the alloy with bio-compatible and excellent nano-material such as graphene oxide. In this research bio-composite coating is composed of CaCO3/GO/CS and coating method that is used is dip coating.
