Abstract
The invention relates the metalwork surface antiseize visbreaking technology. The method comprises the following steps: making the metalwork surface non-smooth surface which has micrometer convex hull and pothole, on the surface of convex hull and pothole coating 30-120 nanometer Al2O3, TiO2 and SiO2 layer with physics or chemical method; the height of convex hull and pothole being 20-400 mu, and the diameter being 20-400 mu.
Description
Technical field
The present invention relates to antiseized, the visbreaking designing technique of metal part surface, particularly a kind of reduction metal parts contacts the adhesion phenomenon that is produced with various resisting mediums (as clayed soil, viscous foodstuff, coal, dust, grease etc.), promptly improves the method for anti-adhesion performance of metal part surface.
Background technology
Contacting the adhesion that is produced between metal parts and the various resisting mediums is a kind of universal phenomenon, it shows two aspects, the one, for motor system, adhesive power between resisting medium and parts surface constitutes sliding resistance and resisting medium to frictional force that parts surface produced, energy consumption when having increased parts work like this reduces production efficiency.As petroleum transportation pipeline, viscous grease contacts for a long time with the transport pipe inner tubal wall, will produce adhesion, increases the petroleum transport resistance, and blocking pipeline reduces petroleum transport efficient; The 2nd, when the adhesive power that is taken place between resisting medium and parts surface during greater than himself force of cohesion, resisting medium will take place accumulate phenomenon in the lip-deep adhesion of working part, make troubles for production, work and life, as cooker, kitchen tools, defend tool etc.
At present, the reduction metal parts contacts the adherent method that produces with various resisting mediums has (1) to prepare inorganic thin film at metal part surface: utilize physics or chemical process such as vacuum evaporation, ion plating, sputter plating, ion-exchange, electroless plating, chemical vapour deposition etc. to form certain thickness inorganic thin film layer at metal part surface; (2) prepare organic film at metal part surface: methods such as utilization spraying form certain thickness organic thin film layer with nylon, polypropylene, tetrafluoroethylene, PVC, polysulfones etc. at metal part surface; (3) metal parts is processed into the uneven surface of non-smooth surface or certain size.Above-mentioned several method all has certain visbreaking, anti-adhesion effects, but certain limitation is arranged again when practical application.As preparing inorganic thin film at metal part surface, the cycle is long, cost is high, and visbreaking, anti-adhesion effects are limited; Prepare organic film at metal part surface, its visbreaking, anti-adhesion effects are the most obvious, but a large amount of organic volatile material has become one of main source of topsoil.Metal parts is processed into the uneven surface of non-smooth surface or certain size, can only plays desorption, visbreaking effect and can not be antiseized.How reducing metal parts and contact the adhesion that is produced with various resisting mediums, realize visbreaking, antiseized function at metal part surface, is the eternal target that the researchist pursues, and also is the international research focus.
Summary of the invention
The objective of the invention is to propose a kind of method that improves anti-adhesion performance of metal part surface, this method is by metal part surface is carried out biomimetic modification, Transform Type design, reduce metal parts and contact the adhesion that is produced, realize visbreaking, antiseized function at metal part surface with various resisting mediums.As a kind of function surface, antiseized, the self-cleaning metal parts of surface requirements such as the present invention can be widely used in cooker, kitchen tools, defends tool, the surface of keeping a public place clean of aircraft, automobile, satellite antenna, radar, the modification of petrochemical industry inner tubal wall.
The present invention is by large number of biological (in land, the water, aerial animal and the plant leaf etc.) visbreaking that body surface had, antiseized and self-cleaning function being observed and being discovered, its body surface contacts with the oversaturated resisting medium of water content, water on its body surface can be taken off rapidly, show very strong hydrophobic performance, show that the gravitation between its body surface material and the water molecules is very little, this is that organism surface has one of major reason of antiseized function.Discover that dung beetle backboard body wall is made up of the collegen filament of cured matter layer, epidermis, reticular tissue.Cured matter layer is positioned at the body wall surface, plays lubrication, makes it have visbreaking, antiseized characteristic.Plant leaf surface main chemical compositions with hydrophobic nature is polyvalent alcohol, polyaldehyde, polyprotonic acid, and its molecular formula: CH-(CH2) n-OH, CH-(CH2) n-COH, CH-(CH2) n-COOH have hydrophobic grouping, show tangible hydrophobic character.The visbreaking of biological surface, antiseized and self-cleaning function phenomenon are further discovered have the biology of visbreaking, antiseized and self-cleaning function, its body surface all is non-smooth morphology.Organism surface is not slick, but presents the non-smooth morphology of micro-meter scale bulge-structure, also has nanostructure on surperficial micro-meter scale bulge-structure, and there is lower-energy material simultaneously in the surface.The top layer lower-energy material comes down to the composite bed that is made of nanostructure.The coupling of this micro-meter scale bulge-structure of organism surface, nanostructure and top layer lower-energy material is the major cause that the surface has visbreaking, antiseized and self-cleaning function.Thus, by experimental study the inventive method has been proposed.
The inventive method is that metal part surface is made the convex closure that is distributed with micro-meter scale or the non-smooth surface of pit, and the Al that is the 30-120 nanometer by physics or the compound one deck particle size of chemical process on the surface of its convex closure or pit

2The thickness of composite bed is 20-600 μ.
The convex closure of described micro-meter scale or the distribution density of pit are 10-60% for the ratio of its geometrical projection area sum on matrix surface and surface of the base body.
The convex closure or the pit of said micro-meter scale are ball crown type, also can be processed into six squares, cylinder shape, square, rhombus, rectangle.
The bionical visbreaking of making by the inventive method, the technical indicator that antiseized function surface reaches are: if metal part surface only is prepared into the uneven surface of non-smooth surface or certain size, or plating one nanometer layer, have certain desorption and visbreaking effect, but act on limited.When metal part surface is made convex closure with micro-meter scale or pit and at the Al of its convex closure or pit surface plating one deck nanostructure
