A Comprehensive Analysis of Extreme Pressure Antiwear Agents
During the high-load operation of mechanical equipment, metal surfaces are prone to friction and wear. To extend the service life of lubricating oil and protect equipment,EP/AW additives have become the core components in the formula.
Extreme pressure wear-resistant agents effectively reduce metal contact and lower the risks of wear and seizing by forming a protective film on the friction surface. In lubricating oil systems such as gear oil, hydraulic oil, and engine oil, they can maintain stable performance under high-temperature and high-pressure conditions, providing long-lasting protection for equipment.
Common extreme pressure wear-resistant agents include sulfur, phosphorus, and chlorine-containing compounds as well as ashless additives. Different types are suitable for different application scenarios. For instance, industrial gear oil requires strong extreme pressure performance, while hydraulic oil pays more attention to the balance between anti-wear and cleanliness.
With the development of equipment towards high efficiency and environmental protection, new ashless extreme pressure wear-resistant agents are gradually becoming a trend, taking into account both performance and environmental protection requirements. Choosing the appropriate extreme pressure wear-resistant agent can not only enhance the anti-wear performance of lubricating oil, but also reduce energy consumption and extend the service life of equipment.
