Definitions
- the invention relates to a method for processing a surface of a substrate in connection with the coating of the substrate surface with a spray layer by means of a thermal spray process, the substrate surface at a pretreatment before coating the substrate surface with the spray layer is roughened, and a device for processing a surface of a substrate in connection with the coating of the substrate surface a spray layer by means of a thermal spraying process comprising means for Pretreatment of the substrate surface by roughening before coating the Substrate surface with the spray layer, the means for pretreatment Blasting machine with accelerators to accelerate the blasting media on the Substrate surface included.
- Thermal spraying includes processes in which spray additives within or melted, melted or melted outside of spray equipment and prepared Surfaces are hurled. The surfaces are not melted.
- Thermal spraying for coating surfaces is known as a process variant autogenous flame spraying or high speed flame spraying, arc spraying, plasma spraying, detonation spraying and laser spraying.
- thermal spraying is, for example, the European standard Can be found in EN 657.
- 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 above-mentioned preparation of the surface to be coated on the Substrate prior to thermal spraying involves roughening the substrate surface.
- this roughening is done by blasting before thermal Spraying with blasting media accomplished.
- blasting agents are usually used Corundum or blasted gravel used.
- Roughening can also be achieved by rough turning or rough grinding. However, a relatively high error rate occurs, which is why the rough turning or rough grinding is only used in borderline cases.
- the invention is therefore based on the object of a method and a device of the type mentioned at the outset, which is a particularly favorable pretreatment of the substrate surface.
- the ones listed above should be included Disadvantages are avoided or reduced as far as possible.
- the abrasive should be disposed of be simplified and also versatile sensitive and critical substrates.
- This object is achieved for the method in that the pretreatment a blasting of the substrate surface to be coated by means of a Includes abrasive which contains one or more fluids hardened by cold contains a solid physical state.
- the Device means for blasting a blasting agent onto the substrate surface to be coated which contains one or more cold solidified fluids in contains a solid physical state.
- the fluids, which are hardened by cold, can operate under normal conditions are in gaseous or liquid state.
- the blasting media can, for example, from solidified carbon dioxide (dry ice) or consist of water ice.
- process parameters such as The speed and size of the blasting media can achieve the desired abrasiveness and be set.
- the choice of Parameters depending on the material used for the abrasive based on its general Expertise possibly also in connection with the implementation of appropriate obvious attempts.
- the material of the Substrates influence the choice of parameters. It should be noted that the roughness for high-energy spraying processes such as high-speed flame spraying, plasma spraying or cold gas spraying does not have to be as high as in the low-energy spraying process.
- the abrasive contains carbon dioxide in a solid state. Due to its physical properties, solidified carbon dioxide in particular offers significant advantages when used as a blasting agent for pretreating surfaces to be coated: carbon dioxide in a solid state (dry ice) has a temperature of around -78 ° C. When heated, carbon dioxide sublimes. When carbon dioxide is sublimed, an explosive increase in volume occurs by a factor of around 600, which effectively supports the treatment. Processing with carbon dioxide in a solid state is residue-free, since the sublimed gaseous carbon dioxide can escape without any problems. Blasting agent preparation or blasting agent disposal is therefore not necessary. Solid carbon dioxide is advantageously used in the form of grated CO 2 flakes and / or preferably CO 2 pellets.
- the blasting is carried out in a fixed manner by means of blasting media Physical state immediately before coating by thermal spraying.
- the means for pretreating the substrate surface a system for coating the substrate surface with a spray layer a thermal spray process.
- spraying can be used to produce an activated surface with the required roughness also cause cooling of the substrate surface.
- the abrasive fulfills a double function: on the one hand it serves as Blasting media for the production of roughness and on the other hand as a coolant for the Cooling the substrate surface. It is even possible that the substrate surface cooled down to a predetermined temperature by blasting with blasting media becomes.
- the cooling of the substrate surface can be accomplished in that the desired cooling is achieved directly by blasting with solid carbon dioxide. But it is also possible that the cold of the sublimed gaseous carbon dioxide is used for further cooling.
- the additional cooling by the sublimed gaseous carbon dioxide can thereby be increased that aids are coupled to the blasting system, which a Prevent the sublimated gaseous carbon dioxide from being drawn off unintentionally quickly and an uncontrolled escape of the possibly still cold gaseous Prevent carbon dioxide.
- aids can include a tunnel, contain a shaft, a rotary tube or the like.
- the blasting according to the invention by means of blasting agents in a solid state of aggregation for roughening the substrate surface can take on a further function in addition to or instead of cooling: namely, the blasting can in addition to roughening also clean the substrate surface.
- CO 2 pellets are particularly suitable here.
- the spray layer is compacted again.
- the quality of the spray layer can be markedly improved.
- Abrasives are used.
- steel balls are used for this.
- Abrasives are used that contain one or more fluids hardened by cold contained in a solid state.
- the blasting media for the Redensification of the substrate surface carbon dioxide in a solid state include.
- the device for processing the substrate surface can in addition to the means for Blasting for pretreatment Means for cooling, cleaning and / or post-compaction have the substrate surface.
- the means of blasting for the Pretreatment can be different or preferably the same as the agents for blasting for the re-densification of the substrate surface.
- the carbon dioxide has a solid state of matter an average size of 10 microns to 10 mm, preferably from 50 microns to 5 mm and particularly preferably from 1.5 mm to 2.5 mm.
- the blasting systems work according to the pressure blasting or suction blasting method.
- the blasting system can comprise a centrifugal wheel system, a pressure blasting system or an inline pelletizer.
- a pressure jet system the solid CO 2 jet particles are generally metered into a gas stream from a storage container, conveyed with the gas stream to a jet nozzle and passed through the jet nozzle onto the castings to be treated.
- the blasting nozzle is usually installed in a blasting gun.
- jet nozzle is to be understood in a broader sense, so that this also includes, for example, an open tube.
- CO 2 pellets are generated on site and accelerated to the substrate surface to be treated.
- the invention has the additional advantages of environmental friendliness and good Can be integrated into automated processes.
