Problems solved by technology

Under certain working conditions, when the ceramic friction pair uses a water-based lubricant, it can only obtain a lower friction coefficient after a long time of running-in, but a large wear rate has been generated during the long-term running-in process. Generally speaking, the currently disclosed water-based lubricants for ceramic friction pairs still have relatively high friction coefficients and wear rates. Therefore, it is necessary to further improve the existing water-based lubricant technology, which is important for improving ceramic friction pairs. The wear condition of friction pairs, improving the wear resistance of ceramic friction pairs, and has great practical application value for industrial equipment equipped with ceramic friction pairs

Abstract

The invention discloses a water-based lubricant composition for a ceramic friction pair, which contains nanoscale silicon dioxide particles, hydramine, a magnesium compound, phytate, nanoscale graphite particles and water. The water-based lubricant composition for the ceramic friction pair provided by the invention has the advantages of low friction coefficients and good abrasion resistance, thereby effectively protecting a surface of the ceramic friction pair and prolonging the service life of the ceramic friction pair.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to a water-based lubricant composition for ceramic friction pairs. Background technique [0002] Ceramic materials have the advantages of small specific gravity, high melting point, high hardness, good chemical stability and corrosion resistance. In practical applications, ceramic materials often form a pair of friction pair parts that are in contact with each other and can move relative to each other, and are used as some parts in mechanical equipment, such as ceramic bearings. Over the past ten years, friction pair components have been used in various fields of national economy and people's livelihood such as aerospace, navigation, nuclear industry, petroleum, chemical industry, light textile industry, machinery, metallurgy, electric power, food, locomotives, subways, high-speed machine tools, and national defense and military equipment. has been increasingly widely used. As...
