COATED HARD METAL MEMBER

摘要

The invention relates to a coated hard metal member that is provided with increased resistance to wear by means of a CVD coating as well as a method for the production thereof. In order to improve the wear behavior of hard metal members, preferably cutting tools, especially reduce crater wear, the sintered compact contains more than 5 percent by weight of mixed carbides of the elements Ti and/or Nb and/or Ta, is superficially provided with a conditioning area which has a certain carbon concentration as well as a nitrogen concentration that increases towards the outside, and comprises a fine-grained or microcrystalline nitride and/or carbide and/or carbonitride coating which is applied according to a CVD process at a temperature exceeding 900 °C.
