Abstract

Thin (Ti,C) and (Mo,C) binary coatings were respectively formed on the surface of H13 steel by Ti++C+ and Mo++C+ dual beams deposition using filtered vacuum arc plasma deposition (FVAPD) system with three MEVVA sources. Using the three-electrode potential-kinetic polarization technique, the corrosion properties of these coatings in acetic acid and sodium acetate solutions or sodium chloride solutions were measured. The results indicate that the binary coatings fabricated by this technique have good compactness and corrosion resistance. A comparison between (Ti,C), (Mo,C) coatings and H13 steel with pure Ti coating in terms of the corrosion resistance was given. Electron diffraction and XRD results show that the structure of the binary coatings presents a mixed polycrystalline and amorphous state. (C) 2000 Elsevier Science B.V. All rights reserved.
