What are the anti-wear additives in industrial lubricants?

Antiwear agent is a high-tech additive in industrial lubricating oil. The antiwear agents used in general lubricating oil are sulfur antiwear agent, phosphorus antiwear agent, sulfur phosphorus antiwear agent, halogen antiwear agent, organometallic antiwear agent and boron antiwear agent, which can reduce mechanical wear and extend the service life of machinery. According to the composition, the additives commonly used in the industrial field are mainly the following three kinds:

1. Graphene

Graphene belongs to a very wide range of solid lubricants. It can form a solid lubricating film after contact with the metal surface, thereby reducing the coefficient of friction. Graphite particles are also particularly easy to penetrate between tightly fitting sliding or rotating friction parts, playing a good lubrication role.

2. Molybdenum disulfide

Molybdenum disulfide (MoS2) is also a good solid lubricant and plays an important role in industrial applications. It not only has a very low coefficient of friction, but also has a very high yield strength, can withstand high temperatures of 350 ° C, and can even work under vacuum conditions at 1200 ° C, which is a good lubrication choice for high-speed mechanical parts.

3. Hexagonal boron nitride

Hexagonal boron nitride (BN), also known as "white graphite", has a fairly low coefficient of friction and does not increase at high temperatures. Because this component is very strong in high temperature lubrication occasions, in recent years it has been gradually applied to a variety of high temperature lubrication occasions, such as the long-term need to withstand high temperature and pressure in the engine, with hexagonal boron nitride lubrication is particularly suitable. Moreover, the performance of hexagonal boron nitride resistance to extreme pressure is also extremely outstanding, and it is particularly suitable for use in heavy load lubrication occasions (such as transmission lubrication).

At present, graphite and molybdenum disulfide are widely used, but in terms of chemical properties, hexagonal boron nitride is more prominent in various properties.
