The hardness,corrosion resistance,bonding force between coating and matrix and friction coefficient of the C/Cr composite coating deposited by non-equilibrium magnetron sputtering were analyzed.

The influence of current density on the microstructure and properties of black Cr-C nano-composite coatings is investigated.

The Cr-C coating was prepared by means of a closed field unbalanced magnetron sputter ion plating technique on high speed steel.

The variation of phase structures,microhardness and adhesion of coatings at different temperatures were investigated in order to evaluate the thermal stability of Cr/C coating.

The results indicate that :chromium carbide in Cr/C coatings prepared by sputtering graphite targets are mainly Cr3C2.

Cr/C coatings were deposited on high speed steel and silicon wafers substrates by Magnetron sputtering,using sputtering graphite target as the mainly source for carbon element.

The oxidation results at 750 ℃ show that the ENCCs have a superior oxidation resistance compared to EMCC, for the as-codeposited Ni-Cr composite coatings of a given Cr particles content, the finer the Cr particles, the better the .

05mol/L H2SO4 was investigated by using potentiodynamic polarization and capacitance measurement in order to investigate the effect of Cr particle sizen on the corrosion behavior of Ni-Cr composite coatings.
