Definitions

  • the invention relates to a method and a device for coating a substrate with high-temperature-resistant plastics.
  • thermoplastics for application temperatures up to around 100 ° C, which are applied to the metallic bodies, for example, by fluidized bed sintering or electrostatic processes. Plastic coatings for higher temperatures, for example 200 to 250 ° C, could not be produced.
  • plastics based on polyphenylene sulfide (PPS) or polyether ketone (PEK) have been available, which have a high chemical resistance, relatively high operating temperatures (maximum continuous use temperature of PPS about 220 ° C, of PEK of about 260 ° C) and good electrical have insulating properties.
  • PPS polyphenylene sulfide
  • PEK polyether ketone
  • These plastics are currently used for the production of bodies by means of injection molding. It has been shown that the firm and dense application to metallic base bodies as a coating has not previously been possible. Due to the inherent process properties, electrostatic methods can only apply thin layers that are not suitable for tribological or flexing loads or for high applied voltages. In many technical fields of application, however, there is great interest in dense layers of plastic which adhere well to metallic base bodies and have the properties indicated above.
  • plastic coatings are required, for example, to protect metallic walls against wet corrosion and as chemical-resistant electrical insulation of components;
  • roll coatings with a smooth surface that can withstand heavy loads are required, which are suitable for use in aggressive media;
  • insulating coatings are required from electrode rollers in order to activate the plastic surfaces by means of corona discharge and to make them printable, whereby besides the resistance of the coating to ozone and UV radiation, high voltage and dielectric strength and low loss angles in the case of HF discharges are required.
  • the invention is therefore based on the object of providing a method and a device for coating substrates with high-temperature-resistant plastics with which dense and well-adhering layers can be produced without continuous pores or cracks.
  • plasma spraying and high-speed flame spraying are known as thermal spray processes for applying materials, for example high-melting metallic or ceramic materials.
  • plasma spraying there are atmospheric plasma spraying, vacuum plasma spraying and inert gas plasma spraying, in which a plasma flow (plasma jet) originating from a high-current discharge serves to melt, accelerate and deposit the sprayed material which is supplied in powder form.
  • the sprayed material is injected near the plasma generation area via injectors which are arranged or fastened in or on the plasma torch.
  • the plasma can reach temperatures of 10,000 ° C and more, which would result in thermal decomposition of the sprayed material if the highly resistant plastic material were fed in via the injectors.
  • the speed of the spray droplets is too slow in conventional burners to overcome their high surface tension, so that no dense, uniform layers can be produced.
  • combustion gases such as propane, propylene, etc. or acetylene react with oxygen in the interior of the burner, as a result of which a reaction mixture under increased pressure is formed, which is formed by a nozzle in the form of a Flame relaxed.
  • the spray material to be applied is supplied in powder form axially in this reaction space or in the initial region of the flame flow, which results in a long desired heating and acceleration time for the spray material.
  • the combustion chamber temperature which is around 3000 ° C, is too high to process the high-temperature-resistant plastic. This in turn can cause cracking of the plastic and, moreover, the particles of the plastic settle on the nozzle walls, which leads to rapid failure of the burner.
  • the coating with high-temperature-resistant plastics is carried out by means of thermal spraying processes with high jet speed, i.e. Speeds greater than 500 m / sec. applied, the powdered plastic being supplied in the colder region of the jet or flame.
  • An essential idea of the invention is to use the powdered plastic material downstream in the colder beam region, i.e. in the plasma process and in high-speed flame spraying, i.e. in the range of temperatures lower than 3000 ° C outside the nozzle or the burner.
  • the distance of the respective injector to the nozzle or the burner depends on the temperature of the emerging flame or the emerging jet.
  • Burners are used with such a nozzle geometry that a widened high-speed jet results, which results in a wider jet and temperature profile with a lower temperature level is generated and the thermal load on the input plastic material is reduced.
  • the nozzle geometry for high jet speed is characterized by a cross-section that initially narrows and then widens again, as viewed from the source. With the correct design and choice of pressure conditions, the flow at the narrow point assumes the speed of sound in order to then become supersonic in the expanding part.
  • the spray material is preferably supplied in powder form, but can also be input in another form, for example in the form of endless threads or tubes filled with powder.
  • the high-temperature-resistant plastics have a high viscosity and surface tension, so that the plastic particles must hit the surface to be coated at high speed, e.g. greater than 200 m / sec and thus high kinetic energy, so that they are as dense as possible , stable and firmly adhering layer is created.
  • additives made of ceramic or metal which can also be in powder form, the viscosity and surface tension can be reduced, which improves the layer quality.
  • additives can be added together with the plastic material, but they are preferably fed separately in the hotter blasting area or into the blasting source, ie to the burner itself, as a result of the thermal Energy the melting of the plastic material is improved.
  • the reduction in the surface tension of the plastic particles promotes a denser layer and at the same time the ceramic or metallic additional particles have a densifying effect due to their higher density and energy due to the transmission of impulses.
  • the hardness of the layer is increased by the additional particles, so that a greater mechanical strength is possible.
  • the thermal expansion of the layer is reduced, thus reducing the risk of stress cracks.
  • the surface can be roughened, for metal, for example, by blasting.
  • a metallic adhesive layer made of NiAl, NiCr, Zn or the like can also be applied to improve the adhesion of the plastic layer to the substrate, the same spray burner as for the plastic coating or an additional spray burner being provided.
  • the plastics considered can be partially crystalline after deposition. They then tend to recrystallize with a decrease in volume, i.e. shrinkage stresses and cracks occur. These properties can be counteracted by preheating the substrate or workpiece at or above about 130 ° C in the case of PPS.
  • Another possibility is the application of a porous intermediate layer, which absorbs the shrinkage stresses, it being possible for this porous intermediate layer to use coarser plastic powder which only melts on the surface but therefore does not shrink.
  • the desired porosity of the intermediate layer can also be achieved by reducing the jet and particle speed, by lowering the burner output and thus the jet enthalpy, and by shifting the particle addition further downstream.
  • the incorporation of hollow spheres made of the same plastic material, the incorporation of yielding material, such as polyethylene, and the aforementioned incorporation of material with low thermal expansion, such as Al2O3, are conceivable.
  • the reference numeral 1 denotes the substrate, which can be, for example, a metal body, such as a pressure roller.
  • the plastic layer 2 made of high-temperature-resistant plastic, for example plastic based on polyphenyl sulfide or polyether ketone, is applied to the substrate by means of a plasma jet 3.
  • the plasma torch 4 consists of a base body 5 and, in the exemplary embodiment, of three injectors 6, 7, 8 fastened to the base body via holders 10, 11 and an injector 9 integrated directly into the expansion part of the nozzle 17.
  • Channels 12 for the gas supply are in the base body , for example, the supply of argon provided, which open into the nozzle channel 13 of the nozzle 17.
  • the nozzle duct 13 consists of a converging part 14, a constriction 15, in which the speed of sound prevails when set correctly, and a diverging part 16, in which the flow speed is then further increased.
  • a cathode 18 projects into the nozzle channel 13, while the nozzle 17 is connected as an anode, so that an arc is formed in the nozzle channel 13, which heats the gas coming from the channel 12 and thus allows the plasma jet 3 to be generated.
  • water channels 18 are arranged in the base body in the region of the cathode and the anode.
  • the injector 6 which is furthest away from the nozzle outlet and thus in the colder area, the high-temperature-resistant plastic in powder form is injected together with a carrier gas into the plasma jet 3, accelerated in it, so that the plastic particles hit the substrate 1 at high speed and form layer 2 there.
  • additional particles can be introduced into the plasma jet.
  • the injector 7 is used, through which, for example, Al2O3 is injected in powder form together with a carrier gas, specifically directly at the outlet of the nozzle 17 in the hot jet region.
  • other particles for example metallic particles, can also be introduced through the injector 7.
  • Another injector 8 which is also directed into the hot jet region, serves for the supply of, for example, NiCr together with carrier gas in order to apply a metallic adhesive layer to improve the adhesion of the plastic layer 2.
  • the powder injector 9 can also be used to supply the additional particles in the constriction or expansion area of the nozzle.
  • the dosages of the particles injected by the four injectors 6, 7, 8, 9 are selected in accordance with the desired intended use of the substrate 1 with the coating 2.
  • the time sequence of the supply of the particles is also determined in accordance with the desired structure. For example, only the injector 8 can inject particles into the plasma jet at the start of the coating, and the other injectors are then actuated with different dosages to achieve a graded build-up.
  • the injector 6 is approximately 20-30 mm from the torch during atmospheric plasma spraying, while the distance of the workpiece from the torch is 100-150 mm. With vacuum plasma spraying, the distance between the torch / injector is approx. 50 mm and the distance between the torch / workpiece is approx. 200 mm.
  • FIG. 2 shows the flame spray gun, which has a reaction space arranged in a base body 20 21, in which channels 22, 23 open for fuel gas and oxygen and, moreover, an inflow channel 24 is also provided for additional particles, for example ceramic powder.
  • water channels 25 are arranged for cooling in the base body 20.
  • the reaction chamber 21 merges into a nozzle 26 which is designed in such a way that the flame jet is strongly accelerated.
  • An injector 28 for the high-temperature-resistant plastic material in powder form and the carrier gas is fastened to the base body 20 via a holder 27 and arranged in such a way that the plastic particles are introduced into the free jet outside the flame spray gun.
  • the distance between the torch and the plastic injection is approx. 30 mm, while the distance between the torch and the workpiece is 200 - 250 mm.
