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 slide without wear for a super-lubricity slide block. The device comprises a super-lubricity slide block and a super-lubricity bottom plate. The super-lubricity slide block is placed on the super-lubricity bottom plate. The super-lubricity slide block is rectangular, and the lower surface is a super-lubricity surface. The super-lubricity bottom plate is strip-type and the upper surface is a super-lubricity surface. The super-lubricity slide block and the super-lubricity bottom plate are equal in width. The edge of the slide block and the edge of the bottom plate are overlaid with the maximum area. The super-lubricity state is kept for a long time, and the slide block can slide for a long distance. The super-lubricity slide block and the super-lubricity bottom plate designed in geometrical shape only to achieve a function of constraining rotation without increasing the process 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.
