Description
Technical Field
The invention relates to a composite super-lubricating coating, in particular to a preparation method of a composite super-lubricating coating with a nano-crimp structure, and belongs to the technical field of surface lubrication.
Background
The friction and wear is a ubiquitous phenomenon of a moving machine, and statistics shows that primary energy of 1/3 in the world is consumed by friction, 4/5 of mechanical parts fails due to wear, and the friction and wear loss accounts for 5% -7% of GDP in industrialized countries. Meanwhile, in the high-technology field, the friction and wear problem is the main reason for causing equipment failure and restricting the reliability of the equipment. The NASA research report in the united states indicates that: a significant proportion of spatial mechanical component failures are associated with frictional wear problems. Lubrication is the most important technical approach to solve the problems of friction energy consumption and material abrasion. The super-lubrication is a new concept technology which is provided in recent years and can greatly break through the limit of the lubricating property of the existing material, the super-lubrication is theoretically zero, and the friction coefficient can be as low as below 0.01, namely 10 in engineering practice-3The magnitude is 1 to 2 magnitude orders lower than the friction coefficient of about 0.1 of the conventional solid lubricating material. Therefore, the development of the super-lubrication technology not only has profound significance for saving energy, reducing consumption and promoting national economy development, but also can generate revolutionary progress on the design and operation reliability of high-technology equipment.
In 2015, Argonne national laboratory researchers in the united states reported on the Science journal (d. Berman, s.a. Deshmukh, s.k. sankaranarayana, a. Erdemir, a.v. sumann. Science 2015, 348, 1118) that graphene and nano-diamond particle composites with diamond-like carbon film formulations could achieve super-lubricity (coefficient of friction as low as 0.004) under macroscopic contact conditions. The principle is that in the friction process, graphene is spontaneously wound on diamond particles to form a nano-roll structure with nano-sheets wrapping the nano-particles, the structure can play a role of a nano rolling bearing, and the nano rolling bearing and a diamond-like carbon film are matched to exhibit an ultra-low friction coefficient. But has the following disadvantages: firstly, the formed graphene-wound diamond composite structure depends on certain friction test conditions, and can show an ultralow friction coefficient only in a proper condition range, so that the stability and condition adaptability of the formed nano roll structure are poor, and the obtained super-lubricating state has a short service life. Secondly, the material system is complex and depends on graphene, nano particles and diamond-like carbon film auxiliary materials, which greatly limit the engineering practicability of the material. Therefore, how to directly prepare the nano material composite with the special coiled structure can realize the cross-magnitude reduction of the friction coefficient between contact interfaces, plays an important role in promoting the acquisition of super lubrication on the engineering scale and the development of super lubrication technology, and has important engineering application value.
