Problems solved by technology

[0003] Traditional friction self-healing additives usually use nano-scale mineral particles to form a friction self-healing coating under high-temperature and high-load friction conditions, but under low friction temperature and load, the lubricating performance is average, and the friction coefficient may even be reduced. Increase

Description

technical field [0001] The invention belongs to the technical field of lubricants, and in particular relates to a method for preparing and using a nanoscale super-slippery powder friction-reducing additive. Background technique [0002] Wear is one of the main causes of material loss. According to incomplete statistics, 1 / 3 to 1 / 2 of energy is consumed in friction and wear; about 80% of machine parts failure is caused by wear. According to the incomplete statistics of my country's five departments of metallurgy and mining, agricultural machinery, coal, electric power and building materials, the annual material loss and energy waste caused by wear and tear in China is as high as 1 billion yuan. Friction and wear not only consume a lot of energy and materials, but also repair or replace parts after the parts fail due to wear, and the resulting shutdown brings huge losses to industrial production. Therefore, it is very important for improving the service life and reliability o...
