It is very huge, if it is possible to reduce useless friction consumption, then can save energy in a large number, reduce noxious gas emission.
The wear-resistant of metallic machine part friction pair, antifriction and recovery technique are the worldwide difficulties of long-standing problem mechanical field
Topic.Generally abrasion resistance of metal refers to rub resistance or antiwear properties of the friction pair under DRY SLIDING, mainly by metal material
Hardness determines that its Major Technology is hardening friction surface.Antifriction then refers to the friction reduced between metallic rubbing pairs, mainly
The reduction of coefficient of friction is embodied in, current Major Technology is finishing friction surface, to reduce its coefficient of friction, or is passed through
The oily matters such as lubricating oil (fat) reduce coefficient of friction as lubricant medium.
Existing lube oil additive realizes the wear-resistant approach of anti-attrition, is mostly using surface filming technology:Such as sulfide lubrication
Form and soft metal plating shoe technology, the technology can play certain reduction abrasion, resist the effect of abrasion, but to having worn out
Or the metal surface for scratching, without repair.Its reason one is that it simply adheres to, is free in surfaces of metallic rubbing pairs, and line is swollen
Coefficient is different from matrix, will not change any size tolerance of workpiece, makes metal surface make very little on several nano thickness
Property change, chemical reaction process is uncontrollable, and modified layer is too meagre and is not sufficiently stable, volatile under high temperature and strong friction condition
Effect, it is easy to fall off, cut from；Two are, be when these materials are into friction surface it is nano level, machine operation for a period of time after work
Impurity is molten with additive to be integrated, and the granularity of material becomes greatly naturally, can produce depositional phenomenon, makes oil circuit internal diameter attenuate, and forms bolt
It is stifled, cause fuel feeding not smooth；Three are, when addition is higher than 0.1%, have change to the tenor laboratory indexes of oil product；Four are, often
Will add during secondary more oil change, there is dependence.

When using, by the addition for adding 20～30ml in every liter of lubricating oil, graphene-based galling is intelligently repaired
Material is added in engine lubricating oil, makes graphene-based galling intelligence repair materials enter machinery by carrier of lubricating oil
Inside, is directly adsorbed to cut, the surface of a wound and the microcosmic surface of parts, during machine operation on the rubbing surface of each contact point
Carry out fine abrasive, the mechanical oxide on surface of cleaning and carbon distribution；And in the operation of body, in rubbing surface metal surface is generated
Ceramal layer.
Graphene-based galling intelligence repair materials are entered after body, and rapid adsorption is on rubbing surface and constantly indulges
To, horizontal disperse and infiltration, increase when load, temperature raise when reaching to a certain degree (by taking cylinder for petrol engine work as an example,
Piston pumps --- inhale, pressure, quick-fried, row, cylinder interior gas pressure is 0.075～0.09Mpa when air inlet ends, temperature
For 370～400k, outburst maximum pressure is 3～5Mpa, and temperature is 2200～2800k.Graphene-based galling is intelligently repaired
Material is exactly the flash temperature using mechanical movement friction moment, and " drop " of temperature is similar to " being stained with fire " process), graphene-based metal mill
Damage intelligent repair materials and there occurs physical change and chemical reaction with metal surface, this process has caused " cermet material "
Reaction between crystal and metallic crystal；Further mutually fusion restructuring eutectic, i.e., micro welding and to aoxidize more new process positive
Running, induction produces new element or novel substance, promotes chemical bond replacement process and defines new keys, make metal micro-assembly robot,
Micro-structural is improved, so as to improve intensity, hardness and the plasticity of metal surface, while it is newly brilliant to form metal in its edge
Lattice, this reaction is persistently carried out, and with new crystal being continuously increased in friction surface, it is compounded to form super with virgin metal surface
Sliding, superhard contact surface --- metal surface ceramic alloy layer.
After forming metal surface alloy layer, the metal-metal, metal between virgin metal friction pair-compound film layer is rubbed
Wipe, be changed into ceramal layer --- the friction between ceramal layer, while progressively be able to will rub on the virgin metal abrasion surface of a wound
Wipe secondary male and fomale(M＆F) and repair smooth, until being optimal between friction pair after fit clearance, because coefficient of friction goes to zero, friction energy
Reduce, the force-chemical reaction produced by friction energy also tends to zero, form the chemical reaction of metal-modified layer (i.e. ceramal layer)
Also can stop.Also being achieved that using the force-chemical reaction of friction energy metal surface self adaptation can be made to be modified.This self adaptation changes
Property can make under certain condition thickness up to 50 microns.Speed, thickness and the friction that metal surface ceramic alloy layer is generated is released
The energy of releasing is directly proportional, and is not that line style increases, but automatically adjust.
From the foregoing, it will be seen that generation of the material of the present invention to metal surface ceramic alloy layer is selective
, it is only combined on the position of galling occurs, and non-abrading section will not occur chemical reaction.It is not engaged in chemical reaction
Material still flowing can be carry by lubricating oil, and abrasion is constantly repaired using frictional energy, when reparation amount is equal to abrasion
During amount, repair and be in poised state with abrasion, be achieved that Instantaneous Situation zero abrasion.
The above, preferably specific embodiment only of the invention, these specific embodiments are all based on the present invention
Different implementations under general idea, and protection scope of the present invention is not limited thereto, it is any to be familiar with the art
Technical staff the invention discloses technical scope in, the change or replacement that can be readily occurred in, all should cover the present invention
Within protection domain.Therefore, protection scope of the present invention should be defined by the protection domain of claims.
