Definitions

  • Synthesis of the composite hard materials also uses oxides, but only mechanical mixtures of the individual oxides (Schwarzkopf, P., Kieffer, R., Cemented Carbides, New York, 1960). In the carbothermal reduction of single oxide mixtures, the constituents of the mixtures largely react as separate particles and phases before the formation of composite hard materials begins.
  • the process for the production of composite hard materials from individual oxide powders has the fundamental disadvantage that, in order to form homogeneous composite hard materials, annealing has to be carried out over a long period of time at higher temperatures and, if necessary, with additives which promote diffusion, such as metals of the iron group.
  • a preferred embodiment of the method according to the invention is that metals, metal oxides and / or metal hydrides of the metals of the fourth, fifth and sixth subgroup of the PSE are also used in the starting mixture.
  • Example 5 Sintered body based on TiCN, in which the hard material according to the invention serves as an additive for increasing the hot hardness
  • a room temperature hardness of HV 10 1484 and a warm hardness of HV 10 (800 ° C) of 631 were measured.
  • the sintered body contains 5% Zr by mass.

Abstract

L'invention concerne un procédé de préparation de poudres de carbonitrure des métaux des quatrième, cinquième et sixième groupe secondaire de la classification périodique des éléments, par calcination de mélanges d'oxydes doubles ou multiples correspondants, de suie et éventuellement d'autres composés contenant du carbone dans une atmosphère contenant de l'azote. L'invention concerne une poudre de carbonitrure des métaux des quatrième, cinquième et sixième groupe secondaire de la classification périodiques des éléments ayant une grosseur moyenne de grain d50 inférieure à 5 mu m, des teneurs en oxygène et en carbone libre inférieures à 1 % en poids, ainsi que des impuretés de métaux du groupe fer inférieures à 0,15 % en poids. L'invention concerne en outre une poudre de titane-ziconium-carbonitrure monophasique, avec un rapport Zr:Ti équimolaire et une teneur en azote allant jusqu'à 10 % en poids d'azote, avec une grosseur moyenne de grain d50 inférieure à 5 mu m. L'invention concerne par ailleurs l'utilisation de la poudre de carbonitrure.
