title: A new material with atomized cobalt-multiwalled carbon nanotubes: a possible substitute for human implants.
abstract: A new material composed of atomized cobalt-multiwalled carbon nanotube has been produced and characterized by thermogravimetric analysis and polarization studies to estimate its lifetime. This does not show cobalt thermal oxidation suggesting that it is confined inside the carbon nanotube matrix. The density functional calculations in the literature predict a strong interaction leading to higher hybridization of cobalt atom and carbon nanotubes. A detailed investigation of the corrosion measurements shows that the new material of thickness 0.8 mm, 1 mm, 1.5 mm and 2 mm would last for 31, 39, 60 and 79 years and it would substitute with cobalt-chromium alloy that is used as a load bearing implant for patients with knee pain or partial denture implant.
