CUTTING TOOL COATED BY PHYSICAL VAPOR DEPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a cutting tool having properties improved for metallic mechanical machining equipped on a surface of cemented carbide, and a hard and wear resisting coating on a surface of a base material.;SOLUTION: The coating is deposited by physical vapor deposition (PVD). The coat is made from metal nitride combined with alumina (Al₂O₃). The coating is made from a structure which is a thin layer and multilayer. This insert is further processed so as to provide various outside layers on each of a rake face and a flank face.;COPYRIGHT: (C)2007,JPO&INPIT
