High temperature resistant and corrosion resistant bearing material and preparation method thereof

Abstract

The invention discloses a high temperature resistant and corrosion resistant bearing material and a preparation method thereof. The high temperature resistant and corrosion resistant bearing material is prepared from, by weight, 5-8 parts of titanium carbide, 3-5 parts of chromium carbide, 4-6 parts of aluminium sesquioxide, 3-5 parts of modified montmorillonite powder, 3-5 parts of tremolite, 8-10 parts of zinc sulfate, 1-3 parts of microcrystalline wax, 2-4 parts of methylcellulose, 6-7 parts of graphene, 8-10 parts of oleic acid, 2-3 parts of sodium triphosphate, 60-70 parts of aluminum, 10-12 parts of zinc, 3-5 parts of nickel, 4-6 parts of iron powder, 1-3 parts of tungsten boride and 1.2-1.5 parts of molybdenum dioxide. The high temperature resistant and corrosion resistant bearing material has the beneficial effects of being resistant to high temperature, high in corrosion resistance, not prone to deformation and the like, is long in service life and applicable to the high temperature corrosion environment and can be used for a long time under the condition of the temperature being 300 DEG C or above.

Description

technical field

[0001] The invention relates to the technical field of bearings, in particular to a high-temperature-resistant and corrosion-resistant bearing material and a preparation method thereof. Background technique

[0002] Bearing is a fixed part in machinery. When other parts move relative to each other on the shaft, it is used to maintain the center position of the shaft and control the movement. It is widely used in aviation, aerospace, national defense, large mechanical equipment, etc. field. Bearing life is a key indicator for judging the quality of bearings, and precision and materials are key indicators that affect bearing life. With the development of modern equipment manufacturing, bearings are gradually shifting from precision research to material research. Therefore, today's high-end bearing research is basically Research on bearing materials. The steel used in traditional bearing materials has poor heat resistance. When the bearing is in a high tempera...
