| Abstract Scope |
Semi-solid processing of metals combines the advantages of forging and casting while shaping of metallic components. Having already matured into an industrial practice for Al and Mg alloys, this technology could upgrade the market for forged steel parts. However, the surface-to-interior temperature differentials in steel thixoforming dies are much larger than with Al and Mg. Combined with the chemical, tribological and thermal interactions between die and formed material confer very specific requirements on tool materials. Hot work tool steel dies are inadequate due to the limited temper resistance of the commercially available grades. Physical Vapour Deposition (PVD) coatings, shown to have beneficial impact on the lifetime of pressure die casting tools, could offer a solution. X32CrMoV3-3 hot work tool steel was coated with AlTiN and AlTiON utilizing cathodic arc PVD technique in the present work. The performance of the coated samples was tested under thermal fatigue and erosive wear conditions. |
