Definitions
- the invention relates to a method for producing composite bodies.
- Composite bodies are becoming increasingly important in industry. Especially composite bodies made of materials with different properties are interesting. Especially with these composite bodies, the material properties can be profitable be supplemented.
- the present invention is based on the object of a method for the production of composite bodies to show which is a simple way of manufacturing enables and / or which contributes significantly to the quality and the To improve properties of composite bodies and thus their area of application expanded.
- the object is achieved in that a basic body of a material is coated by thermal spraying, a powdery filler material by means of a gas onto the surface of the base body to be coated is directed.
- Thermal spraying for coating is known as autogenous as process variants Flame spraying or high-speed flame spraying, arc spraying, plasma spraying, detonation spraying and 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.
- the powdered filler material is applied to the material to be coated Surface of the body passed without the powder particles of the Filler material are melted in the gas jet.
- the statement that the powder particles of the filler material did not melt in the gas jet in the context of the present invention should also mean that the particles in the gas jet are essentially not melted. This can thereby ensuring that the temperature of the gas jet is below the Melting point of the powder particles of the filler material. But even at temperatures of the gas jet from 100 K to 200 K above the melting point of the Powder particles of the filler material can be due to the extremely short residence time Particles in the gas jet melt or melt in the range of milliseconds the powder particles can be prevented.
- the importance of higher gas temperatures or the advantage of heating the gas is that in hotter gases the speed of sound is higher and therefore also the particle speed becomes comparatively larger.
- the cold gas process has compared to conventional thermal processes Spraying a number of advantages.
- the thermal action and force action The surface of the substrate material is reduced, causing unwanted changes the material properties of the substrate material prevented or at least can be significantly reduced. Likewise, changes in the Structure of the substrate material can be prevented.
- the one with the cold gas spraying process created layers have no or at least no pronounced texture, i.e. there is no preferred orientation of the individual grains or crystals.
- the substrate is also not heated by a flame or a plasma, so that none or only extremely minor changes to the base body and no distortion of workpieces due to thermal stress due to thermal spraying.
- Components such as a ceramic tube can be made with one layer Metals, metal alloys, hard materials, ceramics and / or plastics be coated in order to make the pipe gas-tight and / or vacuum-tight.
- Another possibility is an electrically and / or magnetically conductive Apply layer.
- components made of ceramic, Glass, plastic or composite material (e.g. CFRP) over the sprayed-on layer be made conductive.
- components can be reinforced and thereby get a higher mechanical Resilience.
- a thin component that consists of an expensive one Material exists and / or has material-specific physical properties, with an inexpensive spray material, for example a metal, a metal alloy and / or a ceramic.
- an inexpensive spray material for example a metal, a metal alloy and / or a ceramic.
- Base body can be used as the starting material. This basic body will then by spraying on different from the material of the base body Material on the inside and / or outside reinforced to the necessary thickness. It is also possible that the base body has a smaller thickness than that layer sprayed on by thermal spraying.
- a basic body can in particular by spraying on a layer or a coating by means of the Cold spray process will be reinforced.
- 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 above Gases and mixtures of these gases with helium.
- the share of helium in Total gas can be up to 90% by volume.
- a helium content of 10 is preferred up to 50 vol .-% 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 including 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 have extremely smooth spray surfaces, so that there is usually a rework superfluous.
- the gases used according to the invention have a sufficient density and speed of sound to achieve the high speeds required To be able to guarantee powder particles for cold gas spraying.
- the gas can contain inert and / or reactive gases. With the gases mentioned is the manufacture of very dense and particularly uniform coatings possible, which also characterized by their hardness and strength.
- the layers point extremely low oxide levels.
- 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 components.
- 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. Outstanding 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.
- the powder particles can run at one speed can be accelerated from 300 to 1600 m / s. Suitable in the process according to the invention speeds of the powder particles between 1000 and 1600 m / s, particularly preferably between 1250 and 1600 m / s, since in this case the Energy transfer in the form of kinetic energy is particularly high.
- the powders used in the process according to the invention preferably have Particle sizes from 1 to 100 ⁇ m.
- a ceramic tube 1 is shown in FIG. 1 in FIG. Gas-tight around the ceramic tube 1 and to get vacuum-tight, it was - as shown in picture B - by means of thermal Spraying using the cold gas spraying method covered with a layer 2 of metal.
