Modificiranje površina dijelova kalupa za tlačno lijevanje aluminija

Mould parts for aluminium die casting are exposed to a complex wear mechanism and therefore their life is limited. A predominant wear mechanism is the reaction-melting of the mould part working surface, which results in frequent outages and increased mould maintenance costs. In order to extend the life of moulds for aluminium die casting, different procedures of modification and surface coating are applied. So far, the most commonly used procedure has been the salt bath nitriding (the TENIFER process), but data from literature point to the efficient application of diffusion carbide coating, particularly to vanadising due to high chemical and tribological resistance of vanadium carbide.
