Biocorrosion Studies of Ultralow-Temperature-Isotropic Carbon-Coated Porous Titanium


Static, in vitro electrochemical and gravimetric corrosion studies were conducted to evaluate the effectiveness of 0.5-μm ultralow-temperature-isotropic (ULTI) carbon coatings in reducing the metal-ion release rates of porous titanium and solid Ti-6Al-4V alloy. The results indicated significant reductions for both materials, with the corrosion rate of carbon-coated porous titanium being reduced to that of solid uncoated Ti-6Al-4V. Analyses of the results indicate a minimum expected carbon-film lifetime of approximately 38 years.
