Coating material for aluminum die casting and method for coating the same
Disclosed is a coating material for aluminum die casting and a method for coating the same, the coating material including: a CrN adhesion layer formed on a surface of a base material; a TrAlN/CrN support layer formed on a surface of the CrN adhesion layer; and a TiAl(CrSi)VCN functional layer formed on a surface of the TiAlN/CrN support layer. The present coating material solves the hot stamping and sticking problem of a conventional aluminum die casting mold and the like, enhances thermal resistance, and further has enhanced thermal resistance, high-temperature wear resistance, sticking resistance and thermal impact resistance compared to that of a conventional coating material.
