Description

Technical Field

[0002] Molybdenum disulfide coating is a common functional coating used for lubricating light-load low-speed sliding and heavy-load rolling friction surfaces. It can effectively extend the service life of components, has good wear resistance, load-bearing and lubrication properties in high-temperature friction environments, and also has anti-corrosion, oil resistance and cavitation resistance properties. It can play roles in surface protection, anti-corrosion, sealing, lubrication and extending the service life of components, and is an excellent fixed lubricating material for rail vehicle wheels.
