Electrochemical behavior of diamond-like carbon films for biomedical applications

Effect of gold oxide incorporation on electrochemical corrosion resistance of diamond-like carbon

“…The corrosion current densities (i corr ) and corrosion potentials (E corr ) are obtained from the polarization curves. The protection efficiency (P) was calculated by P ¼ 100 1− icorr icorr o , where i corr and i corr o indicate the respective corrosion current densities in the presence and absence of the coating [21]. Electrochemistry impedance spectroscopy (EIS) measurements were also implemented in a 0.17 mol l − 1 NaCl aqueous solution.…”

Synergistic improving of tribological properties of amorphous carbon film enhanced by F–Si-doped multilayer structure under corrosive environment

“…[1][2][3] An unique combination of high hardness and chemical inertness, low friction and sliding wear, and good corrosion resistance [4][5][6][7][8][9][10][11] leads to exhibiting superior tribological properties in corrosive environments.…”

Properties of titanium-alloyed DLC layers for medical applications

“…In order to meet this requirement it is necessary to modify the properties of the surface of bio-inert DLC coatings to make sure that they are actively accepted by the body, and that their tribological properties are preserved at the same time. The layers’ doping with titanium, zirconium, niobium and other elements represents a possible treatment increasing their biological behavior 4 , 8 - 19 . It is known that the biological response of titanium, which is in principle bioactive to a certain extent, can be chemically modified 20 …”
