Abstract
Provide is a friction pair device comprising a friction pair stationary member, a plurality of micro channels, a Tesla valve structure, and a stress application device. The friction pair stationary member includes a friction pair static surface, which friction pair static surface is provided with a dynamic pressure groove. The dynamic pressure groove includes a dynamic pressure groove bottom. A surface of the dynamic pressure groove bottom is provided with micro-nano scale gaps. A super-lubricant is injected into the gaps to form a super-lubricant layer, allowing liquid medium molecules of a liquid-film to move freely along the dynamic pressure groove bottom. A slip velocity of the liquid medium molecules approaches a moving velocity of a friction pair dynamic surface, a slip length of the liquid medium molecules approaches positive infinity, and a super slip surface is formed on the dynamic pressure groove bottom.
