WC-12Co HVOF-sprayed coatings (~400 µm in thickness) reinforced with multiwalled carbon nanotubes (MWCNTs), were deposited on a steel substrate. The aim of this work is to provide and analyze data from HVOF sprayed coatings, concerning the influence addition MWCNTs their tribocorrosion performance, 3.5% NaCl electrolyte. Electrochemical (current density corrosion potential potentiodynamic polar...
