Alloy and process for matrix intrinsic tribocharged manganese oxide coatings for increased service life of hot working tools from S (HSS) iron base alloys

摘要

In iron-base alloys of the "S" or "HSS" type, increased manganese contents are introduced from 2.3% by mass. Under tribomechanical load of appropriately designed hot work rolls, this results in advantages for longer periods of use with the extensive abandonment of nickel and cobalt, because manganese oxides exceed their relevant properties.
