Problems solved by technology

When the bearing works under high temperature or high speed conditions, the high temperature will cause the dissolution of the hardened phase dispersed in the alloy, causing the hardness of the bearing material to drop sharply, resulting in premature failure of the bearing
Moreover, under the condition of long-term high-speed operation of the bearing, the wear caused by it is also very serious.

Abstract

The invention discloses a wear-resistant material. The wear-resistant material is characterized by comprising the following raw materials of, by weight, 15-30 parts of tungsten metal powder, 30-50 parts of titanium carbide, 15-25 parts of copper metal powder, 40-50 parts of silicon carbide grains, 20-25 parts of flaky corundum, 15-20 parts of molybdenum disulfide, 5-8 parts of magnesium oxide, 2-5parts of nickel fluoride, 3-5 parts of niobium and 0.5-5 parts of a flexibilizer. The wear-resistant material has excellent high temperature resistance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of wear-resistant materials, in particular to a wear-resistant material. Background technique [0002] Bearings used in aviation jet engines, metallurgical high-speed rolling mills, and machine tools are required to have good rigidity, low temperature rise and be able to withstand large centrifugal forces because they work under high-speed and high-temperature conditions. Ordinary alloy bearings mainly obtain high hardness through heat treatment (solution→quenching→tempering) process to improve the wear resistance and service life of bearing materials. When the bearing works at high temperature or high speed, the high temperature will cause the hardened phase dispersed in the alloy to melt back, causing the hardness of the bearing material to drop sharply, resulting in premature failure of the bearing. Moreover, in the case of long-term high-speed operation of the bearing, the wear caused by it is also very...
