Wear-resistant metal ceramic mold material

Abstract

A wear-resistant cermet mold material, comprising the following components in weight percentage: Cr: 5.0%-10.0%, W: 5.0%-10.0%, Ni: 1.0%-5.0%, Co: 1.0%-5.0%, Ce: 1.0%-1.5%, Ta: 0.5%-1.0%, Ti: 0.1%-0.5%, Si: 1.0%-1.5%, C: 3.0%-4.5%, Al2O3: 2.0%-4.0%, Y2O3: 4.0% -8.0%, SiC: 2.0%-4.0%, ZrO2: 2.0%-4.0%, and the balance is Fe. The appropriate amount of Ce, Ta, Ti elements, combined with Al2O3 / Y2O3 / SiC / ZrO2 ceramic metal materials, makes the mold have excellent thermal stability, wear resistance, oxidation resistance, high and low temperature resistance, and significantly increases The service life of the mold.

Description

technical field [0001] The invention relates to a mold material, in particular to a wear-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, electrical appliances, instruments and meters, etc., and more than 85% of the parts of bicycles, washing machines, refrigerators, electric fans, air conditioners, cameras and other products must be produced by molds. . 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, selection of mold material...
