Abstract
PURPOSE:To obtain a coated hard alloy suitable for intermittent cutting and continuous cutting by successively forming a layer of the carbide, nitride or carbonitride of Ti, V, Cr or Zr and a layer of one or more among the carbide, nitride and carbonitride of Ti and Al2O3 on the surface of a hard material. CONSTITUTION:A layer of the carbide, nitride or carbonitride of a metal such as Ti, Cr, V or Zr is formed on the surface of a hard material such as a sintered hard alloy or cermet contg. WC or TaC as the principal component by a PVD method to 0.10-6.0mum thickness, and then a layer of one or more among the carbide, nitride and carbonitride of Ti and Al2O3 is formed by a CVD method. The total thickness of the layers is regulated to 0.50-12.0mum. A coated hard alloy having superior wear and chipping resistances and suitable for both intermittent cutting and continuous cutting is obtd.
