The growing competition in the die casting industry requires extension of the lifetime of the moulds. This major demand can be fulfilled by increasing the wear resistance of the mould with hard surface layers to reduce erosion. Combining this feature with high tensile strength and high ductility, thermal or stress induced cracking during the casting process with its cyclic thermal and mechanical stresses can also be minimised or inhibited. However, commonly used hot working tool steels are limited regarding the required properties. Laser cladding is an established technique to increase wear and corrosion protection locally and it offers the possibility to combine properties by multi-graded layers.
