Testing of PVD Hard Coatings Applied to Coining Dies

Abstract:

The requirements on tools used in the production of coins include high quality and reliability, dependent on the materials from which they are made, on manufacturing technology, heat treatment and final operations achieving functional area modification. Properties of the material of coins vary during their production and there is the so-called operational degradation that can be caused by an inappropriate technology of manufacturing. The quality of coining dies is expressed as their service life which ranges from approximately one hundred thousand to one million pieces of coins produced. Therefore, it is necessary to pay enough attention to the service life of coining dies. Surface treatment in the form of the application of hard PVD coatings is one of the ways of increasing the durability of coining die.In the present study, we analysed and tested three types of coatings deposited onto coining dies made of tool steel.
