High-temperature-resistant metal ceramic die material

Abstract

The invention discloses a high-temperature-resistant metal ceramic die material which is prepared by melting and casting the following materials in percentage by mass: 4 to 12 percent of chromium, 3 to 5 percent of cobalt, 1 to 3 percent of molybdenum, 5 to 10 percent of zirconium dioxide, 2 to 8 percent of titanium carbide, 5 to 15 percent of aluminum sesquioxide and the balance of tungsten. The prepared high-temperature-resistant metal ceramic die material has high red hardness, high thermal stability, high abrasion resistance and high high-temperature resistance; moreover, a ceramic phase metal oxide composition of zirconium dioxide / titanium carbide / aluminum sesquioxide / silicon carbide is added, so that the toughness, thermal shock resistance and quick cooling and heating resistance of a die are greatly improved, the mechanical strength of the die is greatly strengthened, and the service life of the die is remarkably prolonged, and can maximally exceed 20,000 times.

Description

technical field [0001] The invention relates to the field of engineering material processing, in particular to a high-temperature-resistant cermet mold material. Background technique [0002] Mold is an important process equipment in various sectors of the national economy and enjoys the reputation of "mother of industry". Mold molding has many advantages such as high efficiency, good quality, saving raw materials, and reducing costs. According to statistics, more than 60% of the parts of airplanes, tanks, automobiles, tractors, electrical appliances, instruments and meters, etc., and more than 85% of the parts of bicycles, washing machines, refrigerators, electric fans, air conditioners, cameras, etc. Mold production. Without molds, there would be no modern industrial development. All countries in the world attach great importance to the mold industry. [0003] Factors that affect the service life of the mold include: design structure, forming and manufacturing process, ...
