Abstract

L'invention est relative à un outil de façonnage céramique, utilisé pour le façonnage par enlèvement de copeaux des matériaux métalliques et non métalliques, d'une part, et protégé contre l'usure, d'autre part, caractérisé en ce que, en position de repos, il ne comporte aucune fissure et se compose d'oxyde d'aluminium ainsi que, dans une proportion de 0,5 à 35 % en poids et de préférence de 1 à 20 % en poids, d'oxyde de zirconium stabilisé, de telle façon que cet oxyde de zirconium stabilisé présente un degré de stabilisation de 40 à environ 100 % et de préférence de 70 à 90 % sur la base d'une teneur en stabilisant de 3 à 9 % en poids sous la forme d'oxyde de magnésium et/ou d'oxyde de calcium. Elle concerne également un procédé de réalisation de cet outil.The invention relates to a ceramic shaping tool, used for shaping by chip removal of metallic and non-metallic materials, on the one hand, and protected against wear, on the other hand, characterized in that, in rest position, it has no cracks and is composed of aluminum oxide as well as, in a proportion of 0.5 to 35% by weight and preferably 1 to 20% by weight, of stabilized zirconium oxide , such that this stabilized zirconium oxide exhibits a degree of stabilization of 40 to about 100% and preferably 70 to 90% based on a stabilizer content of 3 to 9% by weight in the form of magnesium oxide and / or calcium oxide. It also relates to a method for producing this tool.
