Novel electrode material with surface subjected to molybdenum infiltration and titanium nitride deposition and preparation method thereof

The invention discloses a novel electrode material with the surface subjected to molybdenum infiltration and titanium nitride deposition and a preparation method thereof. The preparation method comprises the following steps: firstly infiltrating an alloy element molybdenum into the surface of an iron-based material by utilizing a plasma surface alloying and multi-arc ion plating composite processing technology so as to form a molybdenum-containing infiltrated layer in metallurgical bonding, and then depositing titanium nitride by sputter plating so as to form the novel electrode material with the surface subjected to molybdenum infiltration and titanium nitride deposition. According to the invention, the steel and iron materials with high quantity, wide range and low price are adopted as the electrode material, and the electrode material has the advantages of good processing property, good conductivity, high strength and low cost. After the surface of the electrode material is subjected to molybdenum infiltration and titanium nitride deposition, the electrode material has the advantages of corrosion resistance, abrasion resistance, high strength and hardness, low resistivity and high bonding force; the specific energy and specific power of the electrode can be improved greatly; the contact resistance is constant; the electricity energy consumption is stable and low.
