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.

[0049] The first embodiment according to the present invention has been introduced above, and the method for manufacturing the supersmooth basic structure will be described in detail below.

[0050] Such as Figure 10-15 described, including the following steps:

[0051] In step 1, a substrate 103 is provided, and the substrate can be graphite, such as a highly oriented pyrolytic graphite (HOPG) substrate or natural graphite, or the internal atoms of the substrate material may locally have incommensurate contacts between layers. Preferably, the graphite substrate should also be peeled off the skin, such as sticking the graphite surface with an adhesive tape and then peeling off the tape to peel off the skin, or cutting the graphite from the side with a thin blade.

[0052] Then, in step 2, an island structure is prepared and brought into a state of connecting the island structure to the substrate. Specifically, the following steps may be included: step 2-1, covering the subs...

Abstract

The invention belongs to the field of super-slippery structures, and discloses a super-slippery basic structure, including a base, a plurality of island-like structures on the base and a support layer covering the plurality of island-like structures, wherein each island-like The diameter of the structure is 1 μm to 30 μm, and the height is 10 nm to 10 μm. Each island structure has at least one superslip shear plane, and the upper and lower contact surfaces of the superslip shear plane are in non-commensurate contact state. In addition, a multi-level super-slippery structure is disclosed, the multi-level super-slippery structure includes the plurality of super-slippery basic structures, and the multiple super-slippery basic structures are extended side by side, independently superimposed, shared superimposed or a combination thereof way to form a multi-level super-smooth structure. The invention also discloses a method for forming the super-smooth basic structure. The invention breaks through the limitation that superslip phenomenon only exists in the microcosmic range, and can achieve superslip with large scale and large sliding stroke.

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 ex...
