Abstract RU 2456126 C2

FIELD: process engineering.

SUBSTANCE: invention relates to perfected coating, particularly, to new thick coatings and methods of their production in making cutting tools. Cutting plate with multilayer ceramic coating deposited by CVD process comprises alternating α-Al₂O₃ layers with intermediate layers glued to α-Al₂O₃ layers. Note here that said intermediate layers are made from material selected from the group consisting of TiAlON, TiAlOC and TiAlCON.

EFFECT: higher mechanical properties.
