Definitions

  • the present application relates to a method in which components of at least two different materials are produced by thermal spraying, as well as these components.
  • thermometers The change in electrical resistance with temperature is used in resistance thermometers.
  • the thermoelectric force leads to a flow of current when two different metals form a closed circuit and the two contact points have different temperatures. This effect is used in thermocouples for temperature measurement or in reversing the effect in Peltier elements for cooling.
  • Eligible methods include direct and indirect laser sintering in the powder bed, electron beam sintering and build-up welding.
  • Indirect selective laser sintering is a derivative of selective laser sintering in which the energy of the laser beam used causes the polymer binder enveloping each metallic powder particle to melt and thus the formation of a so-called "green" component.
  • the component strength is increased, the polymeric binder removed and the resulting porosity reduced by infiltration of a low melting point metallic material.
  • the latter process step in particular causes thermal properties in the components which largely correspond to those of the infiltrated metal.
  • Direct selective laser sintering differs from indirect selective laser sintering by the use of higher-energy laser beams, which melt or melt not the polymeric binder but the metallic powder itself.
  • the limitation of this method, as well as in laser cladding, is that no combinations of materials, e.g. Aluminum and steel can be processed.
  • this object is achieved by a component which is made of at least two different materials by thermal spraying, wherein the component by the material combination and their spatial distribution in the component has predetermined properties, in particular mechanical deformability, elongation or heat flow.
  • This provides a component which, through the use of different materials or mixtures of materials, exhibits specific characteristics such as a change in geometry within the component, e.g. for controlling a cooling channel.
  • the component has inner cavities which act approximately as a cooling channel. Due to the special material or material mixture selection in the component can be achieved by adequate Activation of the specifically selected materials or material mixtures, for example, to achieve constrictions or extensions of the cooling channel or a switching effect between two cooling channels or cavities.
  • At least one of the materials used is electrically nonconductive and / or at least one of the materials used is magnetizable.
  • the component may have a self-regulating behavior.
  • thermo spraying method for producing a component according to the invention which is made of at least two materials, by the component during the manufacturing process specifically heat partially or completely supplied and / or withdrawn.
  • thermal spraying preferably lime gas spraying or kinetic compaction
  • particles are joined together to form the desired structure.
  • thermal spraying preferably lime gas spraying or kinetic compaction
  • complex geometries e.g. be realized with undercuts or cavities.
  • areas with different physical properties can be realized in one component. These material transitions need not be abrupt, it can also be realized fluid transitions from one material to another.
  • the change in the mixing ratios can be arbitrary.
  • particles are usually heated in a gas stream and sprayed onto a surface at high speed.
  • the different spraying methods differ from the temperature and the particle speed.
  • process parameters such as particle temperature and particle velocity, material properties (eg hardness, size, geometry, density, oxide content), material combination and substrate temperature, spray spot geometry, feed rate, web overlap, the component or component areas certain properties, such as residual stresses (eg train - or compressive stresses), hardness, porosity or material parameters, such as E-modules assigned.
  • the heating in the manufacturing process of the component by magnetic induction, by applying a voltage and the electrical resistance in the component itself or the cooling can be achieved by the Peltier effect.
  • Figure 1 shows a component through which heat flows are selectively directed
  • Figure 2 shows another mechanically active component
  • FIG. 3 shows a component with a self-regulating cooling channel.
  • FIG. 1 shows a component through which heat flows are directed.
  • a thermally poorly conducting material 1 Embedded in a thermally poorly conducting material 1 is a conductive layer 2, can be tempered by the selected points of the surface 3. The heat supply or removal takes place via lateral contact surfaces 4. Based on this principle, cooling channels can thus be provided with thermally highly conductive branches in order to optimally cool critically loaded regions in a plastic injection molding mold. Another possibility is to install regions of a material of high heat capacity in a complex contour immediately above the surface, in order to dampen local temperature peaks.
  • heat can be locally generated by induction and also distributed in the body by thermally conductive structures. This is particularly interesting for moving o- rotating parts, if a cable or hose connection can not be attached or only with great effort.
  • Combinations with electrically non-conductive layers allow the direct integration of Peltier elements for local cooling or direct heating via the changed electrical resistance of individual areas.
  • the basis for the Peltier effect is the contact of two metals, which have a different energy of the conduction bands. If a current is conducted through two contact points lying one behind the other, heat energy is absorbed at one contact point, so that the electron gets into the higher energy conduction band of the adjacent metal, which causes it to cool down. At the other contact point, the electron falls from a higher to a lower energy level, so that energy is given off here in the form of heat.
  • FIG. 2 shows another example of a mechanically active component.
  • a gradient material 6 is applied to a base material 5, the material composition of which continuously changes with height.
  • the conclusion forms a Cover layer 7.
  • the component forms a bimetal optimized in mechanical deflection.
  • components with variable thermal conductivity can be built up in almost any direction to suit the external boundary conditions, e.g. to ensure an optimal temperature distribution inside a body.
  • gradient materials in thermal spraying materials can be combined that are conventionally difficult or impossible to combine. This includes e.g. the combination of aluminum with copper or steel, stainless steel or iron.
  • the boundary layer is the weak point for many material pairings.
  • a gradient can improve the connection and distribute the load over a larger area. By optimizing the material connection, larger deformations and thus also heavy loads can be permitted.
  • the component and material properties can be further influenced by a heat treatment.
  • FIG. 3 shows a thermally active component in which the thermal behavior can be used for targeted regulation or optimization of the heat flow.
  • individual integral regions e.g. Cooling channels are narrowed or extended.
  • valves can be realized, as can be seen in Figure 3, in which closes or narrowing of a channel another opens or expands.
  • the valve is integrally formed during the manufacturing process with the component.
  • This change in geometry can be realized by electric heaters or internal channels through which a medium for heating or cooling flows.
  • the geometry change can also be self-regulating.
  • the change in geometry can be designed to be self-regulating insofar as certain properties, such as changes in geometry, temperature behavior, are compensated, counteracted or intensified.
  • the movement can be actuated by approximately one sensor, which influences the regulation.
  • a cooling channel in such a component can be provided with thermally highly conductive branches in order to optimally cool critically loaded regions in approximately a plastic injection molding mold.
  • a heat transfer or heat conduction such as by gap formation or gap enlargement or gap reduction in the component can be influenced by a deformation.
  • variable thermal conductivity member can be constructed in almost any direction to suit the external boundary conditions, e.g. to ensure an optimal temperature distribution inside a body.
  • the component is to have predetermined thermal stresses, these are determined by a targeted heating and cooling of the component and by suitable process parameters, such as. Particle temperature, particle velocity, material property, material combination, substrate temperature, spray spot, feed rate, web overlap, introduced. This allows mechanical deformation of the finished component achieved by heating and cooling.
