Abstract
The paper presents the development of layered composite material, which includes a carbide substrate, a ceramic layer and a nano-scale multilayered coating. Each element of a layered tool material fulfills individual functions. The carbide layer provides raised toughness and strength of tool material, the ceramic layer provides resistance of a tool material to oxidation, corrosion and high-temperature weakening at elevated temperatures, the nano-scale multilayered coating decreases thermal-mechanical stresses on the rake face of the tool and eliminates superficial defects of the ceramic.Keywords
