METHOD FOR OBTAINING MULTI-LAYERED COATING FOR CUTTING TOOL Russian patent published in 2015 - IPC C23C14/06 C23C14/24 B23B27/14 

Abstract RU 2538058 C1

FIELD: metallurgy.

SUBSTANCE: vacuum plasma application of multi-layered coating is performed. First, a lower layer of zirconium nitride is applied. Then, an upper layer of nitride of titanium, niobium and molybdenum compound is applied at their component ratio, wt %: titanium 84.5-90.0, niobium 6.0-10.0, molybdenum 4.0-5.5. Application of coating layers is performed with three cathodes located horizontally in one plane. The first cathode consists of titanium and niobium, the second one consists of zirconium and is located opposite to the first one, and the third one consists of titanium and molybdenum and is located between them. The lower layer is applied using the second cathode, and the upper layer is applied using the first and the third cathodes.

EFFECT: improving operability of a cutting tool.
