Problems solved by technology

Taking the graphite super-slip slider as an example, the research shows that the initial non-commensurate super-slippery slider often appears "locked" after the rotation enters the commensurate state, and it is no longer possible to achieve super-slippery sliding

Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0028] First, the ultra-smooth slider and the ultra-smooth bottom plate were prepared, and square graphite islands with a side length of 4 μm were prepared on the surface of highly oriented pyrolytic graphite (HOPG) by masked electron beam exposure and reactive ion etching. A long graphite base plate with a width of 4 μm and a length of 100 μm was prepared using the same process. A tungsten probe is used to push and slide off part of the graphite base plate, exposing the graphite surface with ultra-slip properties, and the upper surface ...

Abstract

The invention provides a device for long-distance zero-wear sliding of an ultra-sliding slider, which comprises an ultra-sliding slider and an ultra-sliding bottom plate, wherein the ultra-sliding slider is placed on the ultra-sliding bottom plate, wherein the ultra-sliding slider is rectangular, Its lower surface is a super-slip surface, the super-slip base plate is elongated, its upper surface is a super-smooth surface, the width of the super-slip slider and the super-slip base plate are equal, the edge of the slider and the edge of the base plate overlap, and the two overlap with the largest area. . The super-slip state can be maintained for a long time, and the slider can slide for a long distance. The super-sliding slider and the super-sliding bottom plate in the present invention can realize the function of restricting rotation only through the design of the geometric shape, without increasing the technological difficulty.

Description

technical field [0001] The invention relates to the field of structural super-slip, in particular to a device for long-distance zero-wear sliding of a super-slidable slider. Background technique [0002] The super-slip phenomenon is a phenomenon in which the friction and wear between non-commensurate solid interfaces are almost zero. In the early days of the phenomenon's discovery, research was limited to nanoscale, low-velocity, vacuum environments. In 2012, Zheng Quanshui's team innovatively discovered the microscale superslip phenomenon through the graphite island system formed by highly oriented pyrolytic graphite etching (see Liu Z, YangJ, GreyF, etal.Observation of microscale superlubricity in graphite.[ J].PhysicalReview Letters,2012,108(20):205503.) This breakthrough laid the foundation for the superslip phenomenon to be applied to micron-scale devices, such as the use of superslippery sliders to design contact hard disk read-write heads, sliders and disks.
