    • The invention pertains to the field of ceramics and relates to dense Al2O3 sinter ceramics with reinforced hard material of the Al2O3/TiCxNyOz type, such as those that can be used as wear-resisting parts. The aim of the invention is to provide Al2O3 sinter ceramics with reinforced hard material having a submicrometer structure in each individual phase. To this end, the structures of said Al2O3 sinter ceramics with reinforced hard material contain a corundum matrix with 0-15 vol. % ZrO2 and 0-15- vol. % of a hard material phase based on titanium TiCxNyOz with a) an oxygen content of z > 0.10 or b) an oxygen content of z ≥ 0.05 and an evident substoichiometry of (x+y+z) ≤ 0.95 of the hard material phase, wherein the mean grain size in each individual phase in the structures is smaller than 1 νm and the structures can exhibit a high Vickers hardness of HV10 ≥ 2,100. Disclosed is also a method whereby the powder starting materials are crushed and mixed together in a liquid medium.
    • 本发明属于陶瓷领域,涉及Al2O3 / TiCxNyOz型增强硬质材料如可用作耐磨部件的致密Al2O3烧结陶瓷。 本发明的目的是为Al2O3烧结陶瓷提供在每个单独相中具有亚微米结构的增强硬质材料。 为此,所述具有增强硬质材料的Al2O3烧结陶瓷的结构包含0-15vol。%的刚玉基质。 %ZrO2和0-15vol。 %的基于钛TiC x N y O z的硬质材料相,其中a)氧含量z> 0.10或b)氧含量z≥0.05且明显的亚化学计量比(x + y + z)≤0.95为硬质材料相, 其中结构中每个单独相中的平均晶粒尺寸小于1μm,并且该结构可以表现出HV10≥2,100的高维氏硬度。 还公开了一种方法,由此粉末起始材料在液体介质中粉碎并混合在一起。
