摘要： A coated cemented carbide member includes a cemented carbide base material containing a binder metal of at least one iron family metal and a hard phase, and a coating layer provided on the surface of the cemented carbide base material. The hard phase contains at least one metal component selected from carbides, nitrides, carbo-nitrides and carbonic nitrides of Zr and/or Hf and WC. A layer consisting of only WC and an, iron family metal or a binder phase enriched layer or a low hardness layer is provided on an outermost surface of each insert edge portion of the cemented carbide base material. The coating layer is a single or multiple layer consisting of at least one metal component selected from carbides, nitrides, carbo-nitrides, oxides and borides of metals belonging to the groups IVB, VB and VIB of the periodic table. Due to this structure, it is possible to improve chipping resistance with no deterioration of wear resistance in the coated cemented carbide member to be used, for example, as a cutting tool.

摘要： This invention relates to a coated cutting tool suitable for high speed cutting working and a process for the production of the same. The feature of the present invention consists in a coated cutting tool comprising a coating layer consisting of an inner layer and outer layer on a surface of a substrate consisting of a cemented carbide such as tungsten carbide-based cemented carbide, etc., the inner layer being composed of a mono-layer of titanium carbonitride in contact with the substrate, a double layer of titanium nitride of 0.1 to 2 .mu.m in thickness, in contact with the substrate, and titanium carbonitride directly above it or a multi-layer provided thereon consisting of titanium carbide, etc., in which the chlorine content in the inner layer is at most 0.05 atom % on average throughout the inner layer, the ratio of the peak intensities of the specified planes in the X-ray diffraction of the above described titanium carbonitride in the specified range and as the inner layer, there are provided coating layers consisting of a first layer of titanium nitride in contact with the substrate and a second layer having a hardness of 160 to 2400 kg/mm.sup.2, and a process for the production of the same. The coated cutting tool of the present invention exhibits a high wear resistance of the coating itself, tenacious adhesiveness of the coating film and substrate and excellent stripping resistance during cutting.
