Abstract
A method for preparing nanometer layer is that rigid balls of 15 mm below diameter are made to impact the surface of metal material with the average impact energy of the balls being 10 to the power -4 to 10 to the power 3 J. The method of the present invention can produce firm nanometer layer and raise the comprehensive performance of engineering metal material.
Description
The present invention relates to nano level metallic substance, a kind of simple method at the spontaneous nanophase layer of metal material surface is provided especially.
Nano crystal material is by the single-phase or heterogeneous crystalline material of forming less than 100nm crystal grain, because crystal grain is extremely tiny, and the interphase density height, when grain-size is little during to several nanometer, interphase density can reach 10
19/ cm
2Therefore nano crystal material can be considered " boundary material " that is made of nanocrystal and two kinds of constituent elements of crystal boundary again.Because this unique texture feature that is different from conventional polycrystalline material and non-crystalline solids material of nano crystal material makes this kind material have many special mechanical propertys, electromagnetic performance and other performance.
At present, the research of field of nanometer material technology mainly concentrates on said three-dimensional body phase nano material [K.Lu, J.Lu:J.Mater.Sci.Technol., Vol.15 No.3,1999], promptly about synthetic, preparation, the constitutional features of block nanometer material, fields such as performance thermostability, but to prepare do not have the cavity, pollution-free and the said three-dimensional body of not having other defective mutually nano material also have certain difficulty, and technology of preparing complexity, the cost height is difficult to realize industrial application.
In fact, the inefficacy of material occurs in the surface of material mostly, so the quality of material surface structure properties directly influences engineering metal material integrated performance index.The conventional engineering material upper layer is carried out nanometer, utilize surface tissue performance that the excellent properties of nano material improves material especially fatigue property, corrosive nature and friction and wear behavior etc., thus the over-all properties and the military service behavior that improve engineering materials.
The method of existing making Nano surface of metal material mainly contains: top coat or depositing nanoization, utilize coating and deposition technique such as PVD, and CVD, sputter coating, methods such as plating generate one deck nanometer layer at substrate material surface.This mainly will consider the bonding force between coating and the matrix, between the coating particle, otherwise causes that easily upper layer peels off or come off.In addition, facility investment is bigger, and production cost is higher, is unsuitable for the preparation of the engineering metal material surface nanometer layer of enormous amount.
The object of the present invention is to provide a kind of preparation method of metal material surface nanometer layer, its small investment of production equipment, simple to operate, industrial being easy to realized, and the nanometer layer that generates should not come off, thereby makes the performance that comprehensively improves the engineering metal material become possibility.
The invention provides a kind of preparation method of metal material surface nanometer layer, it is characterized in that: with the surface of diameter less than the rigidity pill bump metallic substance of 15mm, the energy of the instantaneous bump material surface of average single pill is 10
-4～10
3J.Under the normal circumstances, the Impact energy of single pill is big more, and the defective that material is introduced is many more, and is favourable more to the formation of nanophase; But on the other hand, two factors are depended in the increase of single pill energy, one is the increase of stroke speed, one is the increase of pellet quality, unlimited increase at industrial stroke speed is impossible, and the increase of pellet quality certainly will cause the increase of pellet size, and the influence of metal material surface roughness also be can not be ignored.
Among the preparation method of metal material surface nanometer layer provided by the invention, described rigidity pill is preferably the steel ball of diameter 0.1～12mm; The optimum capacity of the instantaneous bump of single pill is 10
-4～10
2J.
In order to make metal material surface form certain thickness nanometer layer, the surface that a large amount of pills constantly clash into metallic substance is necessary, and the frequency of pill bump material surface can be 10Hz～50KHz, 1 second～20 hours treatment time; Generally, collision frequency is high more, and the time of processing can correspondingly shorten.
The present invention causes material surface to produce severe plastic deformation by mechanical treatment, make surface microstructure pass through dislocation multiplication, motion, bury in oblivion, processes such as rearrangement are refined to nano-scale, promptly form certain thickness nano-structure structure at material surface by the surface of metallic substance being carried out quick severe plastic deformation processing, and the whole components unchanged of maintenance upper layer and material, behind the spontaneous nanometer of material surface, top layer and matrix internal component are constant, grain size distribution: being the nano-sized grains structure in the certain thickness of top layer, is the open grain structure of deformation layer and matrix afterwards.Because the destruction of material is originated from the surface of material, therefore the optimization of surface tissue helps the raising of material fundamental property, and as suppressing aspect the crack growth, small grains is better than coarse grain, aspect opposing crackle crack propagation, coarse grain is better than small grains conversely.The desirable combination of small grains surface and coarse grain matrix is more favourable to the shelf life that prolongs material like this.In a word, the present invention combines the excellent properties of nano material with the engineering metal material, gives property for traditional metallic substance, and this all has very wide prospect in fundamental research and engineering application facet.Below by embodiment in detail the present invention is described in detail.
