Study of PVD-Coated Inserts’ Lifetime in High-Pressure Die Casting Regarding the Requirements for Surface Quality of Castings

by Andrea Sütőová 1,*, Róbert Kočiško 1,*, Patrik Petroušek 1, Martin Kotus 2, Ivan Petryshynets 3 and Andrii Pylypenko 4 Abstract The wear and degradation of tools applied in the high-pressure die casting of Al alloys induce significant financial losses. The formation of failures on the surface of mold parts caused by erosion, thermal fatigue, corrosion, and soldering negatively affects the surface quality
