Importance of selection of the tool steel grades and PVD coatings in cold work tools [PDF]
Materiali in tehnologije, 2008 Tool steel selection and selection of PVD coatings is of key importance for the tool longevity. Therefore it is very important to recognize all present wear mechanisms in tool operation and select the most influential one, which enables proper selection of the tool steel types for the active tool positions.
