2200 to 3000 Kg/mm 2 and the microhardness of the pure metal layer is 600 to 900 Kg/mm 2 . The soft layer of pure metal prevents cracks in the brittle layer,
Moreover, it contributes to increasing the strength of the coating film as a whole. Such a coating is highly resistant to failure under fluctuating loads encountered during machining of structural steel and does not crack when the tool is redressed on one of its cutting surfaces. However, when cutting difficult-to-cut materials (high alloy materials), the durability of the tool is low due to adhesive wear caused by adhesion between the coating material and the cut portion. High temperatures in the cutting area (also a result of the low thermal conductivity of the aforementioned materials) and low cutting speed characteristics for cutting difficult-to-cut materials favor the sticking process. Plastic active pure metals adhere to cut materials more easily than their harder and more inert compounds. Therefore, pure metal layer inclusions in the coating film lead to faster adhesive wear of the coating film as a whole.

的にクラツクが下側層内へ伸びるのを抑える。 In machining difficult-to-cut materials, the high microhardness of group metal carbides and nitrides prevents plastic deformation directed at right angles to the coating surface.
The reinforced coating comprises no more than 500 alternating layers of group metal compound layers and group metal compound layers separated by interfaces. Each interface dissipates crack formation energy during crack formation in the upper layer during the cutting process and substantially inhibits crack extension into the lower layer.
