👉 The edge fluid, also known as the edge lubricant or boundary lubricant, is a specialized type of lubricant designed to minimize friction and wear at the interface between two surfaces in direct contact, particularly where conventional lubricants may fail due to extreme conditions like high pressure, low temperature, or when surfaces are in close proximity. Unlike conventional lubricants that rely on a fluid film to separate the surfaces, edge fluids form a thin, protective layer that adheres to the surface edges, reducing direct contact and thus minimizing wear. This makes them crucial in applications such as microelectronics, precision machinery, and automotive components where maintaining optimal performance under harsh conditions is essential.
