Abstract

The invention discloses a high-strength and good-abrasion-resistance zirconium carbide ceramic material and a preparing method thereof. The high-strength and good-abrasion-resistance zirconium carbide ceramic material comprises, by weight, 16-18 parts of kaolin, 80-95 parts of zirconium carbide, 2-3 parts of tungsten powder, 7-9 parts of black corundum powder, 3-4 parts of stainless steel powder, 6-8 parts of coal ash, 8-12 parts of ceramic waste, 1-3 parts of polysilicic acid ferric sulfate, 2-3 parts of water glass, 6-8 parts of white oil, 3-5 parts of ferro-silicon nitride powder, 1-3 parts of red mud, 1-2 parts of molybdenum disilicide, 2-4 parts of polyvinyl alcohol, 0.5-0.8 part of potassium nitrite, 5-7 parts of auxiliaries and an appropriate amount of water. The zirconium carbide serves as the main raw material of the ceramic material, and the prepared ceramic material has good high-temperature resisting performance, electric conduction performance and heat conducting performance, high mechanical strength and chemical stability; in addition, the fire resistance of the ceramic material is enhanced through the black corundum powder, the ferro-silicon nitride powder and the like; the abrasion resistance of the ceramic material is further improved through the tungsten powder, the stainless steel powder, the molybdenum disilicide, the auxiliaries and the like; and the quality of the product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a zirconium carbide ceramic material with high strength and good wear resistance and a preparation method thereof. Background technique [0002] Ceramic materials are a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. It can be used as structural material, tool material, and because ceramics also have some special properties, they can also be used as functional materials. [0003] 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 perfor...
