Abstract
L'invention concerne la fabrication des matériaux extra-durs. Le matériau faisant l'objet de l'invention, à base de nitrure de bore et contenant des dopes ou additifs d'alliage, est caractérisé en ce qu'il est constitué par une solution solide d'un dope, consistant en un élément du troisième groupe de la classification périodique des éléments capables de former des liaisons tétraédriques, au sein de nitrure de bore d'une modification à arrangement compact, les proportions des constituants de ladite solution solide étant les suivants (pourcentages atomiques) : bore 42 à 61; azote 39 à 50; dope 0,1 à 30; diverses impuretés 0,01 à 2 (en tout). L'invention permet notamment d'améliorer les caractéristiques physico-mécaniques du matériau extra-dur en comparaison du nitrure de bore cubique du point de vue de la dureté aussi bien que de la tenue à l'usure.
