Paper Title:
Characteristics of TiAl-Doped DLC/TiAlN/TiN Multilayered Coatings Synthesized by Cathodic Arc Evaporation
  Abstract

The combinations of TiAl-doped DLC and TiAlN/TiN layers were designed to deposit on the tool steels using cathodic arc evaporation in a continuously single batch process. The economic advantage in depositing the combined coating in one production scale of PVD system is of practical importance. The TiAl-doped DLC as lubricant coatings were synthesized by using arc plasma sources mounted with Ti50Al50-target to emit high energy ion plasma to activate the decomposition of acetylene reactive gases. The results show that the TiAl-doped DLC and TiAlN/TiN combined coatings retained lower friction coefficient at approximately 0.15 during the steady-state sliding. The lubricity and wear resistance of TiAl-doped DLC/TiAlN/TiN coatings is then demonstrated to potentially be applied to the cutting tools with no lubricants.
