From patent document SU 1772777 a method of obtaining colored images on the surface of metal products by processing a metal surface halogenated compound or in a solution of halogenated compounds and exposure to ultraviolet radiation. The method is simple and allows you to capture color images from yellow to black, depending on time and exposure. However, the picture quickly loses color and contrast, tarnish when exposed to environmental factors, wears and loses its consumer properties.
In the patent RU 2357844 disclosed is a method of obtaining a color image on metal surfaces due to the formation of nanostructures in the form of oxide films formed as a result of local heating by the heat source is pulsed. When making way in the impact zone should be established temperature required for formation of an oxide film with a predetermined calorimetric characteristics. The image is giving allows you to print images on any metal surface without pre-processing. However, the technology requires high-precision equipment, may not be copied, time-consuming, requires prior calculation of modes of operation, a slight deviation from which leads to the production of other shades in the image.
For ceramic tiles and colored images are applied with offset printing or decal, for example, see author's certificate SU 92983. However, the basis for drawing the image is not durable materials and is destroyed when exposed to mechanical factors, the image on ceramics tarnish when exposed to sunlight.
Ceramic products have passed the burning image can be applied by sliding the decal. After application the product is re-fired to secure the decal in the glaze. This method allows you to perform multi-color finish, however, it is to some extent slow down the process and is costly. In addition, finish by sliding the decal is not possible after its execution to apply the glaze, which would give the figure the resistance to mechanical damage due to friction.
In the patent DE 3446175 disclosed a method and apparatus for the manufacture of decorated ceramic elements, with the specified method used for finishing the substance is applied on member is for pressing. Then between the membrane for pressing and the first part of the form to create a tight connection on the edge, resulting in the transfer used for finishing substances in the first part of the form. Then the membrane for pressing delete, and between the first part of the form and the second part of the shape formed by the camera for fill, from which pump out the air and which is then filled with a composition of ceramic materials. The composition is subjected to a final pressing with the formation of the element to which the transferred substance, used for decoration.
Closest to the claimed is a method of obtaining images on the surface of the product, including the production of images on the intermediate, in particular, on paper, image transfer on the surface, high temperature calcination products in the furnace with printed image (see patent GB 1120486 on ceramic decalcomanias).
However, there is currently no high-performance technology to obtain high-strength color images on metal surfaces subject to erosion and corrosion.
Before the creators of the present invention had the task of satisfying the need to create strong and durable, simple, low-cost decorative articles coated with the colored image is ojeniyi, photos, words, pictures that are not subject to time and the effect of atmospheric factors.
The technical result is achieved by carrying out the invention is to improve durability of the obtained images, the simplification and cheapening of the technological process of obtaining them, as well as to improve image quality with obtaining different shades.
The technical result is achieved due to the fact that in the method of producing images on the surface of the product, including the production of images on an interim basis, the transfer of image on the surface of the product, the high-temperature calcination products with printed image in the furnace, as a product for transferring images using titanium sheet, before applying the image of the titanium sheet is subjected to high-temperature oxidizing roasting at a temperature of 890-1020°C for the formation on its surface a uniform thickness of the titanium oxide, is maintained at this temperature for 15-90 minutes, while the temperature of the oxidative roasting chosen depending on the desired shade of coloring oxide layer, and the time - depending on the desired thickness, the image transfer is carried out on the surface of the resulting layer of titanium oxide after cooling and re-originale with printed image is carried out at a temperature of 550±15°C.
The technical result is reinforced by the fact that the surface of the titanium sheet in front of oxidative roasting polished corundum grain diameter is not more than 0.01 mm, the surface of the titanium sheet after sanding clean the brush with soap solution and degrease the surface of the titanium sheet after degreasing wipe dry lining sand.
The technical result is also growing due to the fact that for high temperature oxidation annealing using a furnace shaft type with four-sided heating in which the heating elements are located in the walls of the chamber, provided with a top cover.
After oxidative annealing titanium sheet, wipe lining sand to remove roughness of the oxide layer that can damage decornoy film during patterning.
The transfer of the image on the surface layer of titanium oxide on the titanium sheet is performed by the method of sliding the decal.
Titanium sheet coated with the titanium oxide layer image is placed on the bottom of the furnace.
The method of obtaining images on the surface of titanium products is as follows.
All used in advertising, printing and photography metals are relatively short-lived in the exposure and require special storage conditions: dissolved from in the agnosti, UV rays and temperature extremes, whether it be photography, photo print, zincography on the basis of Ag, Al, Pb, CrNi, CrCo at the printing temperature from 20° to 120°C.
Technology create a high-temperature oxide film on the titanium sheet allows the use of titanium sheet as the basis for the subsequent image transfer when it is re-firing the decal sheet deposited on the oxide layer of the titanium sheet. The basis is encountered during oxidative calcination at a temperature of 890°-1020°C on the surface of the titanium sheet to a uniform thickness of 0.002-0,007 mm depending on the duration of firing of the layer of titanium oxide TiO2(see table 1). Uniform heating in an air environment inevitably leads to the oxide layer on the surface at the transition temperature threshold for heat resistance of this material. In the process of the conducted experiments confirmed the effectiveness of the method. Used titanium of different brands. In particular, as non-limiting scope of the invention example, used a sheet of titanium grade VT1-0, the limit of heat resistance of which is 890°C. the Resulting oxide film lasting about 40 Brin - and fine-grained - grain diameter of 0.2-0.5 MCR, uniform in thickness. Remove from the sheet of this film can only power tools using nozzles with a diamond-corundum coating. Depending on the temperature oxidative roasting and time of exposure to this temperature (exposure), differs not only the thickness but also the color and durability of the oxide layer (see table 2). In numerous experiments was identified colors of the oxide layer to titanium of different brands. For titanium grade W 1-0 domestic production it stretches from the cold blue-gray (under the influence of 890°C, exposure time 20 minutes) to light-gray-white (oxidizing roasting at 940-950°C, exposure time 20 minutes). Found that the quality of the surface oxide layer of the sheet is determined by the speed and uniformity inside the chamber of the furnace.
The method is as follows.
The surface of the titanium sheet, for example, mark W 1-0, before oxidation polished corundum grain diameter of not more than 0.01 mm; occurs when the grinding depth of the surface of the metal oxide layer to be more durable. After grinding the surface of the titanium sheet is thoroughly cleaned with a brush with soapy water and degreased with acetone or mineral spirits or other solvent. Then, the surface of the titanium sheet was wiped dry lining sand, to remove the last traces of solvent or stains from water. It is noted that only a clean, evenly-brushed titanium sheet will give the same uniform oxide layer on color and composition.
For high-temperature oxidizing roasting oven was used mine t the PA with four-sided heating elements, located in the chamber walls, camera cover opens up. Used electric resistance TK-SP-2008, volume 90 liters with a maximum temperature of 1300°C, the heating elements of the alloy HUT (wire), production of the Moscow plant "Thermoceramix".
Obtained after baking sheet with titanium oxide layer was removed from the oven, leaving grease again rubbed lining sand to remove all roughness and unstable surface oxide layer that can damage decornoy film during patterning. Titanium sheet, ready for printing an image. Images were obtained on a special decolam the printer. All of dekalim printer sheet decornoy paper with a gelatin layer containing the image caused declname paints that can withstand temperatures up to 930°C. Used low-temperature (550°C) varnish for glass (flux) Spray Tecnici company Baltea D.C. - manufacturer of Italy. There is a similar flux of domestic production. This varnish was coated sheet decornoy paper and carefully dried for 1-2 days at room temperature of 20°C. As an alternative used drying in a tunnel dryer at 50°C for 40 minutes Then transfer method decoline image is shifted with a damp paper moistened with water oxide layer of titanium sheet and carefully ironed.
Titanium sheet with the image printed on the oxide layer, was placed on the bottom of the furnace, which should be flat or fitted with bottom regions, preventing deformation of the sheet during heating. Closed the lid, ensuring that the particles lining not included on the image. Then made a second annealing titanium sheet with decolam image deposited on the oxide layer. This kept the temperature of 550°C ±15°, kept for 15 min (see table 2). Total shutter firing was 90-105 minutes the Dried product was subjected to mechanical strength tests.
The result is unexpectedly resistant mechanically strong, high-contrast toned image on a light durable resistant to any external factors the basis of titanium.
Environmentally friendly creating an oxide layer on the titanium sheet was allowed to conduct all necessary tests and to obtain high-quality samples with decolam image
Tests showed undeniable advantages decal, obtained on the oxide layer of titanium. The image on the titanium sheet high strength and plastic. The titanium sheets of 0.6 mm and more are the ideal media images, graphics - everything that can print becolny printer on decornoy paper.
Leaves all titanium obtained on the oxide layer of the image at a temperature not higher than 550°C durable is, practically timeless. Unlike all crassopetala printers, even with UV protective lacquer layers, the image on the oxide layer of titanium sheet does not crack, not cloudy, not fade, not destructurarea and is not affected by the fungus and corrosion
Decoline paint, proven a thousand-year history of porcelain, moving to a titanium carrier is lightweight, strong, durable, flexible, heat-resistant. About the necessity of such media for museums not to mention. The Fund of rare graphics and pictures can be protected by creating a copy on Titan - durable and light for travel, exposures to the sun, at any humidity, in the absence of glasses. The combination of price-quality with cost to create guarantee insurance and investment attractiveness, as each sheet is individual and is guaranteed against forgery his micropatterns grinding the basis of the oxide layer and the resulting microdefects when baking the image.
Titanium sheet can be a carrier of high-quality original photography, you should take into account first of all the durability and lightness of the material of the carrier, not easily copied, i.e. copyright protection defined by the technology of obtaining of the image.

Device for serial application of multiple overlapping paint layers onto a substrate contains substrate route and substrate drive for moving the substrate along a route, where paint application sections are adapted for applying paint onto substrate, which paint includes reaction-incapable paint thinner and has viscosity less than 4000 centipoises, and also management system, which manages transportation of substrate along a route. Viscosity of first layer of liquid paint, applied onto a substrate in one of paint sections, is increased due to evaporation of at least a part of paint thinner from first paint layer to higher viscosity compared to viscosity of second paint, applied on top of first paint layer in next paint section, located at a certain distance from first paint section, up to viscosity, sufficient for "crude" application of second liquid paint layer during transportation of substrate between paint sections.
