Abstract

The invention provides a super-lubricity basic structure, a multi-stage super-lubricity structure, a component with the super-lubricity basic structure or with the multi-stage super-lubricity structure and a forming method of the super-lubricity basic structure, and belongs to the field of structural super lubricity. The super-lubricity basic structure comprises a substrate and a plurality of island structures on the substrate, wherein each island structure is provided with at least one super-lubricity shearing face, and the upper contact face and the lower contact face of the super-lubricity shearing face are in an incommensurate contact state. The invention further discloses the multi-stage super-lubricity structure which comprises multiple super-lubricity basic structures, wherein the multiple super-lubricity basic structures form the multi-stage super-lubricity structure in a side-by-side extension mode, an independent stacking mode, a sharing-type stacking mode or other combination modes. The invention further discloses the forming method of the super-lubricity basic structure. According to the super-lubricity basic structure, the multi-stage super-lubricity structure, the component and the forming method of the super-lubricity basic structure, the limit that the super-lubricity phenomenon only exists in a microcosmic scope is broken through, and large-scale and large-slippage-stroke super-lubricity can be achieved.

Description

technical field [0001] The invention relates to the field of structural super-slip, in particular to a large-scale, large-sliding distance solid super-slip structure, which is used in fields requiring ultra-low friction or ultra-low wear. Background technique [0002] Friction and wear have always affected people's production and life. According to statistics, about one-third of the world's energy consumption is on friction, and about 80% of mechanical parts fail due to wear, and the losses caused by friction and wear in industrialized countries are as high as 5%-7% of GDP; An important problem in joints is to obtain better lubrication performance to reduce friction and wear problems (see Unsworth A.Recent developments in the tribology of artificial joints[J].Tribology International,1995,28(7):485-495.). Therefore, humans have been trying to control and reduce friction for thousands of years, trying to create a material or structure with extremely low friction and extremely...

AI Technical Summary

Problems solved by technology

[0005] Due to the difficulty of preparing large-scale single crystal materials, the solid structure lubrication that can be realized experimentally is limited to the micron or smaller scale, and the preparation of large-scale structural ultra-smooth devices has not yet been realized.
