Definitions
- the invention relates to a method for coating substrate materials thermal spraying, a powdered filler material using a gas is passed onto the surface of the substrate material to be coated without the powder particles of the filler material are melted in the gas jet.
- 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 powder. With thermal In addition, thermal post-treatment can be provided for spraying.
- Air In the cold gas process according to the prior art (EP 0 484 533 B1) is used as the gas Air, helium or a mixture of air and helium are used.
- Air the powder particles reach a speed of 300 to 600 m / s when in use from helium to a speed of 1000 to 1200 m / s and when using a Air / helium mixture to a speed in the range of 300 to 1200 m / s accelerated.
- the particle speed can also be in the range between 300 and 1200 m / s can be controlled by heating the gas from 30 to 400 ° C.
- the gas is used at a pressure of about 5 to about 20 bar. It will be a powder with a particle size of 1 to 50 microns used.
- 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.
- EP 911 424 A1 with the same seniority describes a method of manufacture of composite bodies by means of thermal spraying.
- EP 911 426 A1 with the same seniority describes a method of manufacture of self-supporting molded parts using thermal spraying.
- WO 95 07 768 A describes a special coating process by formation a mixture of particles and gas flow as suspension and acceleration the resulting two-phase flow to supersonic speed coating substrate for producing a coating while changing the physico-chemical properties of the coating material.
- the mixture from particles and gas is a pseudo-liquid particle-gas suspension.
- the process is based on a change in the physico-chemical properties of the coating material.
- the carrier gas is compressed Air used.
- both inert gases used because of the purity of the layer as well as gas mixtures can be.
- CH 658 045 A describes in connection with the manufacture of glass molds for hollow glass production machines after blasting treatment with corundum Creation of a protective layer from an alloy by plasma spraying or Flame spraying without melting. This process enables in particular Contrary to cold spraying and hot spraying with melting that Manufacture of glass molds that are used and damaged after Glass production can be repaired by subsequent thermal spraying.
- the object of the present invention is the method mentioned at the outset further training, and to improve the quality of the coatings and / or to increase the applicability and performance of the cold gas spray process.
- the powder Gas carrying filler material is a nitrogen-containing, oxygen-free gas or Contains carbon dioxide or mixtures thereof.
- Gas containing nitrogen in the context of the present invention is nitrogen or to understand a gas mixture containing nitrogen.
- gases are called gases which are free of are elemental oxygen, this indication referring to technical purities related, so contaminations of elemental oxygen are allowed.
- 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 be done ensure 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 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 Coatings produced according to the invention adhere very well to a very wide variety Substrate materials, for example on metal, metal alloys, ceramics, glass, Plastics and composites.
- the manufactured with the inventive method Coatings are of high quality and have an extremely low level Porosity and have extremely smooth spray surfaces, so that usually a rework is unnecessary.
- the gases used according to the invention have a sufficient density and speed of sound to achieve the required high speeds to be able to guarantee the powder particles.
- the gas can contain inert and / or reactive gases.
- the method according to the invention enables with these gases the production of very dense and particularly uniform coatings, which are also characterized by their hardness and strength.
- the coatings produced according to the invention are extremely small Oxide levels. They have no or at least no pronounced texture, i.e. it there is no preferred orientation of the individual grains or crystals.
- the substrate will furthermore not heated by a flame or a plasma, so that none or only extremely small changes to the substrate and no distortion of workpieces due to thermal stress.
- Helium can advantageously be added to the gas.
- the proportion of helium in the total gas can be up to 90 vol .-%.
- a helium content of 10 to is preferred 50 vol .-% observed in the gas mixture.
- 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 gases or gas components are in particular to mention nitrogenous gases.
- a gas jet with a pressure of 5 to 50 bar used.
- gas pressures in the range from 21 to 50 bar.
- Excellent spray results were achieved, for example, with gas pressures of around 35 achieved in cash.
- the high pressure gas supply can, for example, by the in the German patent application DE 197 16 414.5 methods described there or described gas supply system can be ensured.
- the powder particles can run at a speed 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 speeds of the powder particles between 1250 and 1600 m / s, because 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.
