In order to reduce the adhesion tendency of aluminum melt on the die casting mold and extend the service life of the die, multi-arc ion plating was used to deposit Ti/TiN/CrN multi-layer coating on the surface of 8418 hot-working mold steel.Corrosion resistance of 8418 steel and the Ti/TiN/CrN coating against Al alloy melt was studied.X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy were used to study the microstructure, phase constituent and phase composition of the materials involved.
