Abstract

The invention discloses a zirconia-based micro-nano composite ceramic material. The zirconia-based micro-nano composite ceramic material comprises raw materials in parts by weight as follows: 60-80 parts of zirconia, 30-50 parts of aluminum nitride, 10-15 parts of titanium carbide, 10-15 parts of titanium nitride, 8-15 parts of zirconium carbide, 4-8 parts of neodymium oxide, 3-5 parts of magnesium oxide, 3-5 parts of aluminum hydroxide, 1-3 parts of chromium and 2-6 parts of nickel. All the raw materials adopt nanoscale powder. The zirconia-based micro-nano composite ceramic material has high ageing resistance, good combined mechanical properties and excellent antifriction and wear-resisting performance, and the combination property of a mold material is improved.

Description

technical field [0001] The invention belongs to the field of composite ceramic materials, in particular to zirconia-based micro-nano composite ceramic materials. Background technique [0002] Ceramic materials have excellent thermal stability and wear resistance, and are ideal materials for making forming molds. They have great development prospects, but their toughness is poor, so they have not been widely used in the mold industry. In order to overcome the brittleness of ceramic materials and improve the reliability of use, one or more second-phase materials can be added to single-phase ceramics to improve their brittleness and reliability, and various ceramic matrix composites have emerged. Compared with traditional ceramic mold materials, the performance of nano-composite, especially nano-micro-composite ceramic molds has been greatly improved. Contents of the invention [0003] The purpose of the present invention is to provide a zirconia-based micro-nano composite c...
