Definitions
- the invention relates to a method for producing a band-shaped metallic composite material by high-temperature dip coating of a metallic one
- Carrier tape on the surface of which a thin layer of this support material is crystallized by solidification when the carrier tape is guided through a molten metallic support material, this being different from the material of the support tape, a device for carrying out the method and a product produced by this method.
- EP 0 467 749 B1 discloses a process for dip-coating a strip consisting of ferritic, stainless steel with aluminum, in which the strip is heated in various steps in a non-oxidizing atmosphere at different temperatures until the strip is finally in a
- Coating bath is immersed.
- EP 0 397 952 B1 discloses a process for the continuous hot dip coating of stainless steel strip with aluminum, in which the strip is attached to a series of.
- an argon-flushed housing In an argon-flushed housing
- Magnetic current devices is passed, the tape is cleaned by an argon plasma discharge while heating to the temperature desired for the dip coating and the cleaned tape is immersed in a bath of molten aluminum.
- DE 195 45 259 A1 discloses a method and a device for producing thin metal strands, in which a metal strip is guided vertically through a molten steel and thereby has a layer thickness of 20-2%. the starting metal band is crystallized. Depending on the thickness, the metal strip is preheated to a temperature between room temperature and a maximum of 900 ° C. This process is used to produce composite sheets in which one of the materials used is stainless steel, austenitic or ferritic steel.
- the invention has set itself the goal of creating a method, a device and a product in which an intimate, error-free connection of the individual layers of the composite material consisting of different materials can be achieved with simple means.
- the invention achieves this goal in that the carrier tape is preheated before being passed through the molten support material on its surface and pretreated by the addition or incorporation of chemical elements in such a way that during the passage through the support material between the pretreated surface of the carrier tape and the the surface of the shell of the carrier tape crystallizing through diffusion processes creates a binding area made of a gradient material, the liquidus temperature of which is at least in parts of this binding area below the liquidus temperature of the carrier tape material and the covering material.
- a shock shell solidifies on the surface in a very short time due to the resulting undercooling and the good foreign bacterial conditions, which initially has no bond with the carrier tape.
- Diffusion processes during and after the dipping process result in concentration courses in the binding area between the shell and the carrier tape, which cause local alloy formation with a defined chemical composition.
- a gradient material with a changing chemical composition is created in the course of the binding area itself.
- the local concentrations cause a lowering of the liquidus temperature (calculation according to Wensel and Roeser), which in parts of the Binding area is below the liquidus temperature of both the carrier tape and the support material.
- the lowering of the liquidus temperature is usually accompanied by an even greater lowering of the solidus temperature. It is thus possible for liquid phase components to be present in the binding area, even though the carrier tape and overlay material are in the solid state.
- the liquid phase components ensure welding between the base and the base material.
- FIG. 4 There, the course of the local liquidus and solidus temperatures is shown schematically in a diagram, in which the temperature is plotted over the location coordinate.
- T iiq and T SO ⁇ illustrates the existence of the liquid phase in the binding area, the base material (carrier tape) and support material being in the solid state.
- the temperature cannot be selected so high that the carrier tape is melted in the molten bath or loses strength so severely that it breaks off during transport.
- the core of the carrier tape can be kept at an appropriate temperature, while for the desired intimate connection the liquidus temperature can be lowered at least at the tape surface, in order to enable diffusion-supported mixing in the liquid.
- various means are shown in the invention which support diffusion-borne alloy formation in the binding area.
- These agents can already be added to the carrier tape, but they can also be applied to the tape as a support or alone from the outside, in that, according to the invention, to prepare its surface, the carrier tape is passed through a medium which contains the corresponding chemical elements which at least partially penetrate into the surface .
- the medium can be a gas such as nitrogen, hydrogen, carbon monoxide, ammonia or carbon dioxide or, according to another feature of the invention, a liquid such as sulfuric acid, liquid ammonia or be liquid nitrogen. It is also possible that the medium is a solid such as a cyan salt, carbonate or blood lye salt.
- the carrier tape consists of steel which has a carbon content> 20 ppm or a in the area of its surface
- the transport speed of the carrier tape and / or its immersion depth or immersion length in the liquid support material is advantageously set in such a way that a minimum immersion time of 50 msec is maintained, the total immersion time being limited by the desired layer thickness and the one already described above Risk of melting of the carrier tape.
