Abstract

The invention discloses a composite metal ceramic material. The composite metal ceramic material is prepared from the following raw materials in parts by weight: 10 to 20 parts of silicon dioxide, 2 to 5 parts of anhydrous cupric sulfate, 2 to 8 parts of silicon carbide, 5 to 10 parts of kaolin, 1 to 5 parts of quartz sand, 5 to 10 parts of tungsten dioxide, 2 to 5 parts of antimonous oxide, 1 to 5 parts of thorium sulfate, 1 to 3 parts of germanium nitrate, 2 to 5 parts of lanthanum bromide, 5 to 10 parts of aluminum magnesium silicate, 1 to 5 parts of calcium carbonate, 5 to 10 parts of sodium silicate, 2 to 5 parts of fly ash and 1 to 5 parts of yttrium orthovanadate. The composite material has the advantages of better high temperature resistance, bending strength and toughness, easily-obtained raw materials, lower preparation cost and low process conditions; the composite metal ceramic material can better meet the demands of people.

Description

technical field [0001] The invention relates to a ceramic material, in particular to a composite cermet material. Background technique [0002] Cermet has the advantages of both metal and ceramics. It has low density, high hardness, wear resistance, good thermal conductivity, and will not be brittle due to sudden cooling or heat. In addition, coating a layer of ceramic coating with good air tightness, high melting point and poor heat transfer performance on the metal surface can also prevent the metal or alloy from being oxidized or corroded at high temperature. Cermet not only has the toughness, high thermal conductivity and good thermal stability of metal, but also has the characteristics of high temperature resistance, corrosion resistance and wear resistance of ceramics. Cermets are widely used in rockets, missiles, shells of supersonic aircraft, flame vents of combustion chambers, etc. [0003] According to the different percentages of each constituent phase, cermets ...
