Antiwear additive

An antiwear additive is a type of chemical compound that is added to lubricants, such as oils and greases, to reduce wear and tear on mechanical components during operation. These additives help form a protective layer on the surfaces of moving parts, minimizing direct metal-to-metal contact and preventing friction-related damage. Antiwear additives work by creating a boundary film that protects surfaces during conditions of high load or low lubrication conditions.
