Abstract

The invention provides a metal ceramic wear resisting material. The metal ceramic wear resisting material is characterized by comprising the following components in parts by weight: 20-30 parts of boron nitride, 25-35 parts of chromium carbide, 5-10 parts of scandium nitride, 5-10 parts of molybdenum nitride, 8-10 parts of niobium boride, 8-10 parts of titanium silicide, 4-6 parts of boron silicide, 1-3 parts of carbon fiber, 1-4 parts of amido montmorillonoid, 1-5 parts of cerium powder, 1-3 parts of strontium powder, and 3-6 parts of zirconium powder. The invention further discloses a preparation method of the metal ceramic wear resisting material. The metal ceramic wear resisting material is low in preparation cost, high in toughness and wear resistance, excellent in high-temperature resistance and corrosion resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of wear-resistant materials, in particular to a cermet wear-resistant material and a preparation method thereof. Background technique [0002] In recent years, with the development of science and technology and modern industry, people have higher and higher requirements on the wear resistance of materials. Abrasion is the most basic type of failure of prefabricated parts. It is commonly found in many industries such as metallurgy, mining, thermal power, machinery, cement, coal mines, etc., which causes a huge waste of raw materials and a huge consumption of energy. It can be seen that improving the wear resistance of mechanical equipment and parts can effectively reduce energy consumption and increase labor productivity. It is particularly important to develop wear-resistant materials with excellent performance. [0003] At present, common wear-resistant materials include metal materials and ceramic materia...
