Resum

Corrosion and tribocorrosion studies of a TiB_xC_y/a-C coating deposited on AISI 316L steel have been performed in an aqueous solution of 0.26vol.% acetic, 0.16vol.% peracetic and 0.18vol.% hydrogen peroxide (commercial product Oxonia 1vol.%). The corrosion current density of the TiB_xC_y/a-C coating ranges on the same order as bare steel but with a significantly decreasing friction (0.1 vs. 0.6) and wear rate (~10 times lower). The compact microstructure of the coating hinders the access of the aggressive electrolyte to the substrate, preventing the onset of the corrosion attack, while maintaining an excellent tribological behavior in strong oxidant solutions.
