Anti-wear agents are high-tech additives in industrial lubricants. The anti-wear agents used in general lubricants include sulfur anti-wear agents, phosphorus anti-wear agents, sulfur-phosphorus anti-wear agents, halogen anti-wear agents, organic metal anti-wear agents and boron anti-wear agents, which can reduce mechanical wear and extend the service life of machinery. According to the composition, the commonly used additives in the industrial field are mainly the following three:
1 Graphene
Graphene is a solid lubricant with a very wide range of applications. It can form a firm lubricating film after contacting the metal surface, thereby reducing the friction coefficient. Graphite particles are also particularly easy to penetrate between tightly fitting sliding or rotating friction parts, playing a good lubricating 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 friction coefficient, but also has a very high yield strength. It can withstand high temperatures of 350°C and can even work at 1200°C under vacuum conditions. It 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 very low friction coefficient and does not increase at high temperatures. Since this component is very strong in high-temperature lubrication, it has been gradually applied to a variety of high-temperature lubrication occasions in recent years. For example, the engine needs to withstand high temperature and high pressure for a long time, and hexagonal boron nitride is particularly suitable for lubrication. In addition, hexagonal boron nitride is also extremely outstanding in its ability to resist extreme pressure, and is particularly suitable for use in heavy-load lubrication occasions (such as gearbox lubrication).
