The Ti+C+N film was co-deposited on H13 steel by Filtered Vacuum Arc Plasma Deposition (FVAPD) operated with a modified cathode. The co-deposited layer was effective for the improvement of surface hardness and corrosion resistance. The nano-hardness value of the co-deposited film is 1.3 times more than that of undeposited sample. The corrosion behavior measurement shows that the corrosion resistance for acid corrosion and pitting corrosion was improved greatly. It is owing to the formation of the new ternary ceramic phase TiC0.7No.3 in the co-deposited layer. The mechanism of property improvement is discussed.
