Boundary lubrication

Boundary lubrication refers to a lubrication regime that occurs when two surfaces are in close contact but not fully separated by a lubricating film. In this state, the lubrication is provided by a thin layer of molecules that forms on the surface of the materials, reducing friction and wear. This type of lubrication is crucial in situations where the load is high, speed is low, or during start-up conditions, when traditional fluid lubricants may not fully separate the surfaces. Proper boundary lubrication helps prolong the life of machinery and reduces energy loss.
