Prevention of Reactive Soldering on Die Casting Parts
During the die casting process of aluminium alloys, the damage on the mould components is caused not only by the thermal fatigue, but also by the reactive soldering of aluminium on the mould surface. Thus, the mould life time is limited. A principal cause of damage on the working surface of the die casting parts is reactive soldering, resulting in frequent outages and increased maintenance costs of die casting tools. In order to lengthen the life time of moulds for die casting of aluminium, different modification procedures and the coating of die casting parts are applied. So far, a frequently applied procedure of surface modification has been nitrocarburising in a salt bath, as well as the application of nitride, carbide and oxide layers obtained by the Physical Vapour Deposition procedure. In addition, different procedures for obtaining stable oxides on the surface of die casting parts are applied. Data found in literature confirm a successful application of diffusion coating with carbide layers, in particular of vanadizing, due to the chemical and tribological resistance of vanadium carbide. Thus service life of tool parts applied in technologies of Die Casting is increased.
