- DE 195 20 885 C1 describes a method for thermal spraying Layer of a metal or a metal alloy described. With this Processes can spray layers with a thickness of 20 mm and more getting produced.
- the spray layer can be bonded to the substrate be used. At least 60% by weight of the wettable powder particles have the Impact on the substrate at a temperature between the solidus and the liquidus temperature of the metal alloy or up to 80 ° C below the Melting temperature is.
- the present invention is based on the object of a method for the production to show molded parts that simplify the manufacture of molded parts, cheaper or made possible at all and / or which contributes significantly to to improve the quality and properties of molded parts. In particular, should the production of molded parts from or with difficult to form materials be made possible.
- a base body is coated by thermal spraying, a powdered filler material by means of a gas on the to be coated Surface of the base body is passed without the powder particles of the Filler material are melted in the gas jet.
- Thermal spraying for coating knows that as process variants autogenous flame spraying or the high speed flame spraying that Arc spraying, plasma spraying, detonation spraying and that Laser spraying.
- Thermal spray processes are essentially characterized in that they enable evenly applied coatings.
- Coatings can be applied by varying the spray materials can be adapted to different requirements.
- the spray materials can be processed in the form of wires, rods or as powder. With thermal In addition, thermal post-treatment can be provided for spraying.
- An essential feature of the invention is that the powder particles of Filler material in the gas jet should not be melted.
- the aim is to have the powder particles of the filler material in the Do not melt the gas jet (i.e. convert it completely into the liquid phase) that but is not aimed that the powder particles of the filler in Gas jet as a mixture of on and / or unmelted particles and on the other hand, composed of molten particles.
- the statement that the powder particles of the filler material not be melted in the gas jet can be ensured that the Temperature of the gas jet below the melting point of the powder particles Filler material is.
- the cold gas spray process has compared to conventional processes of thermal spraying has a number of advantages.
- the thermal action and The effect of force on the surface of the substrate material is reduced, as a result unwanted changes in the material properties of the substrate material can be prevented or at least significantly reduced. You can also changes in the structure of the substrate material are largely prevented.
- a base body can be sprayed on by a layer or a layer Coating reinforced to a desired thickness using the cold gas spraying process become.
- Relatively thin base bodies e.g. a relatively thin walled after A molded part produced by a conventional method as a starting material be used. This body is then sprayed on same or different material on the inside and / or the outside reinforced to the necessary thickness. Special advantages can be achieved if the Base body has a smaller thickness than that by thermal spraying sprayed-on layer This variant facilitates the production of molded parts or with materials that are difficult to form.
- Moldings made of easily plastically deformable are also suitable as base bodies Material, for example copper, aluminum or alloys containing them.
- the Base bodies can be relatively thin, for example in the range from 0.1 to 10 mm, preferably 0.5 to 5.0 mm. After spraying a particularly heavy malleable material by means of the cold spray process can then Molded articles, for example mechanically or chemically by dissolving, be removed from the sprayed-on layer. In this case, only that Spray layer the desired molded part.
- This method supports in particular Dimensions the production of molded parts from or with difficult to form materials.
- a raw body according to one of the possibilities described above or produced by a combination.
- This raw body does not have to have the desired shape of the molded part to be produced, on the contrary, e.g. consist of a flat sheet metal body.
- the workpiece can (the coated raw or basic body or just the layer) in one or several of the known forming processes (drawing, deep drawing, rolling, pressing and the like) are processed further. This is how you finally get that desired molding.
- the advantage of this variant is that sprayed sheets or raw bodies are very fine-grained and practically texture-free. Your deformation takes place therefore very uniform and allows higher degrees of deformation than with sheet metal were produced by annealing or rolling.
- the gas for thermal spraying can be nitrogen, helium, Argon, neon, krypton, xenon, a gas containing hydrogen, a carbon-containing one Gas, especially carbon dioxide, oxygen, an oxygen-containing Contain gas, air, hydrogen or mixtures of the aforementioned gases.
- gases air and / or helium known from EP 0 484 533 B1 are suitable nitrogen, argon, also for the gas carrying the powdered filler material, Neon, krypton, xenon, oxygen, a gas containing hydrogen, a carbon-containing one Gas, especially carbon dioxide, hydrogen or mixtures of the aforementioned gases and mixtures of these gases with helium.
- the proportion of helium of the total gas can be up to 90% by volume. A helium content of 10 to 50 vol .-% observed in the gas mixture.
- the so produced Layers adhere very well to a wide variety of substrate materials, for example on metal, metal alloys, ceramics, glass, plastics and composite materials.
- the coatings produced using the method according to the invention are of high quality, have an extremely low porosity and possess extremely smooth spray surfaces, so that there is usually no need for reworking
- the gases used according to the invention have a sufficient density and Speed of sound to the required high speeds of the powder particles to be able to guarantee.
- the gas can be inert and / or reactive gases contain. With the gases mentioned is the production of very dense and special uniform coatings possible, which is also due to their hardness and distinguish strength.
- the layers have extremely low oxide contents. They have no or at least no pronounced texture, i.e. There is none Preferred orientation of the individual grains or crystals.
- the substrate becomes further not heated by a flame or a plasma, so no or only extreme minor changes to the base body and no distortion of workpieces due to thermal stress due to thermal spraying.
- the gas jet can be heated to a temperature in the range between 30 and 800 ° C are, all known powdery spray materials are used can.
- the invention is particularly suitable for wettable powders made of metals, metal alloys, Hard materials, ceramics and / or plastics.
- the temperature of the gas jet selected between 300 and 500 ° C. These gas temperatures are particularly suitable for the use of reactive gases or reactive Gas constituents. As reactive gas or gas components are in particular Hydrogen admixtures, carbon-containing gases or nitrogenous gases mention.
- a gas jet with a pressure of 5 to 50 bar used. Above all, working with higher gas pressures brings additional Advantages because the energy transfer in the form of kinetic energy is increased. It gas pressures in the range from 21 to 50 bar are particularly suitable. Excellent Spray results were achieved, for example, with gas pressures of around 35 bar.
- the High pressure gas supply can, for example, by the in the German patent application DE 197 16 414.5 described method or the one described there Gas supply system can be ensured.
