Development and research of vacuum-plasma coatings for increase of shearing dies operability
The technological principles of low-temperature deposition of multilayer vacuum-plasma coatings with the increased operational properties on various types of die steels with the assistance of accelerated argon molecules beam are off ered in the article. Four standard architecture of vacuum-plasma coatings: Ti/(Ti, Zr) N, Cr/CrN, TiN/TiCN/(Ti, Cr) N and Ti/(Ti, Al) N are considered. It is shown that deposition of vacuum-plasma coatings of the listed structures at the optimum modes considerably reduces intensity of wear of shearing dies therefore quality of shaped products several times increases
