CUTTING PLATE MANUFACTURING METHOD Russian patent published in 2013 - IPC C23C14/24 B23B27/14 

FIELD: machine building.

SUBSTANCE: proposed method involves deposition of a two-layered coating onto a hard-alloy base using a vacuum-plasma method. As a bottom layer, there applied is titanium and molybdenum nitride, or titanium and chrome nitride, or titanium and niobium nitride at the temperature of 600°C and at smooth increase in nitrogen pressure within the period of time of the layer deposition in the plant chamber of 7.5·10^-4 Pa to 4.3·10^-3 Pa. As a top layer, the above nitride of the bottom layer alloyed with zirconium is applied at the chamber nitrogen pressure of 4.3·10^-3 Pa and temperature of 500°C.

EFFECT: increasing wear resistance of cutting plates.
