Definitions
- the invention relates to a device for cold gas spraying.
- the invention relates to a cold gas spray gun and a device with such a cold gas spray gun and a method that uses a cold gas spray gun according to the invention.
- Nozzle are accelerated to supersonic speed, wherein the powder material is injected before or after the nozzle throat in the gas jet and accelerated toward the substrate.
- the particle temperature on impact increases with the process gas temperature. This leads to a thermal softening and ductilization of the powder material and lowers the critical velocity of the impacting particles. As the speed of sound also increases, raising the process gas temperature increases both particle velocity and particle temperature upon impact. Both have a positive effect on the order efficiency and coating quality.
- the process gas temperature always remains below the melting temperature of the Spraying used powder material. In the cold gas spraying method, therefore, a "colder" gas is used in comparison to other spraying methods in which the powder particles are melted by the gas. As with injection molding, where filler metals are melted by hot gas, the gas must be heated in cold gas spraying as well.
- a spray gun with a Laval nozzle consisting of an inlet cone and an outlet cone which abut one another at a nozzle neck.
- the Laval nozzle is supplied with air under high pressure via an air heater and a mixing chamber in which an air powder is mixed. The powder is accelerated through the Laval nozzle as a supersonic nozzle and heated by the air heated in the air heater without it melts.
- a disadvantage of this prior art is that the material strength and strength of the components of the spray gun must be designed very large in order to withstand the high pressure at high temperatures of the material can, as the material strength decreases sharply with temperature.
- a cold gas spray gun with a nozzle for accelerating the gas jet and particles is known, which is in a converges converging nozzle portion and a nozzle outlet, which merge into one another at the nozzle neck, and a powder injection tube which ends more than 40 mm in front of the nozzle throat.
- a device for cold gas spraying with a spray gun with a nozzle and a heater for gas heating wherein the heating is divided into at least two heaters for gas heating and a postheater is attached directly to the spray gun while a second freestanding preheater a line is connected to the spray gun.
- a device for high-pressure gas heating with a pressure vessel through which a gas flows, a heating element arranged in the pressure vessel and an insulation are known.
- the insulation is arranged on the inner wall of the pressure vessel and there are means for heat dissipation of the pressure vessel so that the pressure vessel has a lower temperature than the heated gas.
- the usable process gas pressure can be raised to well above 35 bar without excessively increasing the weight of the cold gas spray gun due to large material and wall thicknesses. Due to the internal insulation of the high-pressure gas heater and / or mixing chamber and the Laval nozzle, the components under pressure can be operated at significantly lower temperatures and thus higher material strength. The insulation further avoids unnecessary thermal losses to the environment and creates less Cost of gas heating. Finally, there is also a lower inertia of the cold gas spray gun when commissioning, since not the relatively large masses of wall material must be heated, and increased durability, due to the lower temperature stress of the materials. An increase of the process gas pressure and thus an increase of the gas density has an effect together with an increase of the gas pressure
- the pressure vessel of the high-pressure gas heater and / or the mixing chamber are lined with an insulation consisting of solid or flexible ceramic insulating material.
- the pressure vessel of the high-pressure gas heater and / or the mixing chamber is insulated by a gas gap between an inner shell enclosing the gas and an outer shell.
- high pressure gas heater, mixing chamber and Laval nozzle are linearly and concentrically aligned.
- the flow direction of the gas between high-pressure gas heater and mixing chamber can be deflected by an angle of up to 60 ° to each other. If the flow guidance in the region of the two-phase flow of supplied particles is continuous and free of edges, this reduces the risk of particle deposits. Before the mixing chamber can be achieved by a deflection of up to 60 °, a more compact design of the cold gas spray gun.
- the mixing chamber is at the same time the convergent section of the Laval nozzle.
- the converging portion of the Laval nozzle has a length between 50 and 250 mm and has a conical or concave or convex inner contour.
- the converging nozzle section is insulated from the inside or consists overall of an insulating material, in particular ceramic.
- the pressure vessel and / or the mixing chamber and / or the convergent section and / or the divergent section may consist in whole or in part of titanium or aluminum and their alloys.
- the spray gun can be made particularly easy, as well as by the use of aluminum.
- the latter is particularly cost-effective as a construction material for the cold gas spray gun.
- the distance between the particle feed in the mixing chamber and the nozzle throat 40 to 400 mm preferably 100 to 250 mm.
- a sufficiently long residence time of the particles in the heated gas can be achieved by heating the particles.
- the flow cross-section of the mixing chamber and / or the convergent section may be between 5 and 50 times the nozzle throat cross-sectional area, preferably between 8 and 30 times, more preferably between 10 and 25 times to at least 70% of the distance from the particle feed to the nozzle throat amount.
- the flow velocity in the region between the particle feed and the nozzle throat is not too small, so that the two-phase flow of gas and particles is maintained. Particle agglomerations and deposits on walls, which can disturb the operation of the cold gas spray gun sensitive, such as in the case of a nozzle clogging, are prevented.
- the nozzle throat has a diameter between 2 and 4 mm
- the diverging portion has a length which corresponds to 30 to 90 times the diameter of the nozzle throat, and at the same time the area ratio of the cross section at the end of the diverging portion to that of the nozzle corn cross section 3 and 15 and the inner contour is conical, or convex or concave.
- the gas is supplied under a pressure of 15 to 100 bar, preferably from 20 to 60 bar, more preferably from 25 to 45 bar and a flow rate of 30 and 600 m 3 / h.
- the particle feed can consist of a tube supplied sideways at any angle or of one or more bores at the end of the high-pressure gas heater or in the mixing chamber.
- the heat output of the heating element related to the flow cross section in the nozzle throat is 1.5 to 7.5 kW / mm 2 , preferably 2 to 4 kW / mm 2 .
- the power volume of the heating element may be from 10 to 40 MW / m 3 , preferably from 20 to 30 MW / m 3 .
- the spray gun the gas via a plastic tube, in particular Teflon, which is connected to a second high-pressure gas heater, preheated to 230 0 C, or via a H preciselygasmetallschlauch, preheated to up to 700 ° C, fed.
- the total heat output of the high-pressure gas heater and the second high-pressure gas heater relating to the flow cross section in the nozzle throat is 4 to 16 kW / mm 2 , preferably 5 to 9 kW / mm 2 .
- the gas can be supplied in a method according to the invention after the high-pressure gas heater in the mixing chamber with temperatures greater than 600 0 C, preferably greater than 800 0 C, more preferably greater than 1000 0 C are supplied.
- more than 80 percent by weight of the particles fed into the mixing chamber in the nozzle throat reach 70% of the gas temperature in the nozzle throat, measured in Kelvin.
- a mixture of particles may be used whose mass is at least 80% of particles of grain size between 5 and 150 microns, preferably between 10 and 75 microns and more preferably between 15 and 50 microns.
- the impact temperature of coarser particles can be significantly increased by efficient preheating of the particles in the hot process gas stream.
- coarser particles do not lose their temperature again as quickly in the expanding jet of the nozzle and the use of high-quality and precisely specified powders of particles is in coarser fractions (-38 + 1 1 ⁇ m; -45 + 15 ⁇ m; -75 + 25 ⁇ m; -105 + 45 microns) unproblematic and cheaper.
- the handling and promotion of spraying is much easier than with conventional powder fractions with -22 microns and - 25 + 5 microns.
