METHOD OF OBTAINING MULTILAYER COATING FOR CUTTING TOOL

摘要

A process for producing a multilayer coating for a cutting tool comprising a vacuum plasma deposition of a multilayer coating, characterized in that applied to a lower layer of titanium nitride compounds, chromium and zirconium in a ratio, wt.%: 78,0-84,0 titanium, zirconium 6 , 0-10,0, 8,0-12,0 chromium and an upper layer of zirconium nitride and applying coating layers is carried disposed horizontally in one plane three cathodes, a first of which operate a composite of titanium and zirconium, a second - zirconium and have the opposite of the first, and a third composite made of titanium and chromium and disposed between them, the lower layer is applied using the first and third cathode, and the upper layer - using the second cathode.
