Description
Technical field
The present invention relates to special-purpose mixed-powder in the restorative procedure of a kind of metal friction, wear surface and this method.
Background technology
There is friction that wearing and tearing are just arranged, there is the material consumption of half in the whole world in wearing and tearing, the metallic rubbing pairs overwhelming majority in the engineering goods causes inefficacy by surface abrasion, just surface abrasion transfinites, the part of wearing and tearing only accounts for the very fraction of whole parts, just cause scrapping of whole part, the loss that wearing and tearing cause is surprising.
Adopt technology such as thermal spraying, surfacing, brush degree, repair welding, built-up welding to repair the galling surface at present, its compensation disappearance physical dimension is restored one's working ability, reached economical with materials and maintenance cost purpose.But these technology all are processed offline; plant equipment need be disintegrated, dismantles, be shut down during processing; and have high requirements in the grasp to technology; complex treatment process; for example the coating after surfacing, the spraying technology reparation needs machined just can reach instructions for use; coating machine difficulty of processing with high rigidity is very big, the very high unfavorable factor of cost.
Occurring some recently utilizes lubricating oil or lubricating grease to be carrier; the metal that will contain repair; pottery; ceramic-metallic micron order or nano level powder composition are brought the friction surface contact zone into; utilize under the fricative in working order temperature and pressure of friction pair; at its surface deposition; formation has high rigidity; the repair layer of the wear resistant friction reducing compensate for wear effect of low-friction coefficient; this class technology is online recovery technique; plant equipment need not disintegrated during processing; dismounting; shut down; and the surface after repairing is without any need for advantages such as machineds, so this class technology is to repair the focus of area research now.Through market survey with to user's understanding and test, this class technical products exists reparation speed slow, DeGrain, and to no effect, not repairing of having aggravated surface abrasion on the contrary and caused counter productive when producing low friction energy under the friction duty condition that has.Cause this type of technology and technical products to have the effect instability, reparation speed is slow, restricted application and unsafe factor.Its reason is:
1, this type of Study on Technology and application at present still is in the starting stage, defectiveness on the prescription of its repair materials, lack the global design prioritization scheme, numerous adverse factors are not taken into account, under the temperature and pressure that produces when just relying on friction, impel repair materials and metal surface to repair reaction, the friction energy that produces under the friction duty condition that has is not high, or formed in the metal surface under the condition of a part of repair layer, low-friction coefficient causes mechanical resistance to reduce, the energy decreases that produces during friction has obviously reduced the speed of next step reparation or stops to repair, and Here it is causes the main cause of the slow and DeGrain of reparation speed.
2, lack the component that the metal surface is had cleaning and mobilizing function on the formation of repair materials, see it all is rough from the metal surface of microcosmic, tend to and environmental activity, have three pollution layers at least on the top layer, it is common dirty layer, surface and the gas of environment or the interactional adsorption layer of fluid molecule and the oxide layer that forms with oxygen in the atmosphere, here the author spells out, repair materials and metal reaction depositing crystalline, the metal surface must be " fresh ", free of contamination, activation have very high surface can, ability fast reaction speed and quality like this.Otherwise the speed of reaction slowly maybe can not be reacted.In this class technology, when just utilizing the material with repair function to rub in the CONTACT WITH FRICTION district, to metallic surface finishing, this obviously is not good method.The metal surface can not well be cleared up, heavier is, when repair materials rubs in the CONTACT WITH FRICTION district, the surface these pollution layer materials can with repair materials generation partial reaction, cause the segregation of repair materials composition, also can wrap up repair materials, cause the inefficacy of repair materials, the more important thing is by the pollutant of partly clearing up and the contaminant particles of metal oxide layer, be distributed in lubricating oil, the fat, can aggravate the wearing and tearing to the metal surface, this is to cause the unstable and unsafe reason of effect.
