Abstract

The invention discloses a nano-alumina-based cermet mold material and a preparation method thereof, wherein the cermet mold material is prepared from the following components in parts by weight: nano-alumina, boron nitride, samarium powder, Slag powder, titanium hydride, lithium vanadate, aluminum borate whiskers, gallium trioxide, nano calcium carbonate, titanium diboride, europium iodide, niobium carbide, yttrium trioxide, erucamide, tantalum carbide, Molybdenum sulfide, methylvinyldichlorosilane. The cermet mold material provided by the invention shows good bending strength, fracture toughness and long service life, and overcomes the disadvantages of the traditional cermet mold materials such as easy cracking and poor toughness which lead to short service life. At the same time, in the actual use process, the mold prepared by the invention is easy to demold, has strong wear resistance, and the quality of the molded product is good and the yield rate is high.

Description

technical field [0001] The invention belongs to the field of mold materials, and in particular relates to a nano-alumina-based cermet mold material and a preparation method thereof. Background technique [0002] Mold is an important process equipment in the manufacture of communication equipment, industrial devices, and auto parts. It enjoys the reputation of "mother of industry" and has many advantages such as high efficiency, good quality, saving raw materials, and reducing costs. According to statistics, more than 60% of the parts in the mechanical processing products of various departments need to be produced by using molds, so molds play an important role in industrial production and development. [0003] Metal-ceramic mold materials have the advantages of high strength, high hardness, high temperature resistance, and wear resistance, and are widely used in hot extrusion molding. Among the cermet mold materials, alumina-based molds and silicon nitride-based molds are t...
