Abstract

The invention relates to a metal ceramic material, and belongs to the technical field of ceramics. The metal ceramic material is prepared from the following components in parts by weight: 55-65 partsof ceramic powder, 20-30 parts of ferric oxide, 10-15 parts of alumina, 1-5 parts of quartz sands, 7-10 parts of silicon nitride, 20-30 parts of flux, 15-23 parts of a fluxing agent and 8-10 parts ofa water-proofing agent, wherein cupric oxide and aluminate are embedded in the alumina substrate, and the aluminate exists in a mode of small flaky particles and flakes. The ceramic metal material hasexcellent performance and good stability, can be used for prolonging the service life of products, and can meet the requirement of various industries.

Description

technical field [0001] The invention relates to cermet materials and belongs to the technical field of ceramics. Background technique [0002] Ceramic material is an inorganic non-metallic material made of natural or synthetic compounds after forming and high-temperature sintering. It has the advantages of high melting point and high hardness and is widely used in aerospace industry, mechanical engineering, electronics, automobiles, metallurgy, energy, etc. , biology and other fields, it is an indispensable key material in cutting-edge technology. Decoration of ceramic surfaces as exterior surfaces of equipment has become very important. [0003] Cermets In order to make ceramics resistant to high temperature and not easy to break, people add some metal powder to the clay for making ceramics, thus making cermets. However, the existing cermet materials have low tensile strength and flexural strength, and their properties need to be improved. Contents of the invention [...
