Definitions

  • the invention relates to a steel sheet tempered with a deterministic surface structure and coated with a metallic coating, and a method for its manufacture.
  • Steel sheets of the generic type tempered with a deterministic surface structure are known from the prior art, see for example the patent specification EP 2 892 663 B1 . Furthermore, tempered steel sheets of the generic type are also in the published disclosure documents DE 10 2019 214 155 A1 , DE 10 2019 214 155 A1 , DE 10 2019 214 136 A1 and DE 10 2019 215 580 A1 described by the applicant. From the disclosure document DE 10 2012 112 109 A1 , which forms the basis for the preamble of claims 1 and 5, respectively, a steel sheet textured with a pattern and coated with a PVD coating is also known.
  • gas phase deposition for example in physical gas phase deposition
  • a starting material is converted into the gas phase with the help of physical processes (laser, temperature, ion bombardment) and then brought to condense on a surface.
  • physical processes laser, temperature, ion bombardment
  • many materials and material combinations in the form of a wide variety of layer structures can be applied to a surface in an advantageous manner.
  • zinc- and aluminum-based layers and high-melting layers are of particular interest, for example for hot forming.
  • a disadvantage of these layers is the directional application, i.e. the material always comes from a fixed angle as long as the material is not rotated.
  • Gas-phase deposition is economical for the steel industry when a high throughput can take place as quickly as possible, so that the material (steel sheet) is supplied in the form of strips or sheets and coated, so that the layers are applied in a direction-dependent manner.
  • Skin-passing causes bulges, undercuts, steep flanks, fractures and/or roughening on the surface of the steel sheet. Since the skin-passing step is usually a necessary step before coating, in order to preferably set the mechanical parameters in the steel sheet and to ensure a sufficiently large surface for the coating as well as the downstream processes (oiling, etc.), irregular surfaces can be treated with Hard to avoid many peaks and undercuts, which in turn can have a negative impact on vapor deposition coating. It is therefore a major challenge to design dressed surfaces in such a way that optimal and homogeneous coating by gas phase deposition, especially independent of direction, is possible.
  • the task is therefore to provide a steel sheet tempered with a deterministic surface structure, which allows an optimal and homogeneous coating by gas phase deposition.
  • the provision of a defined surface structure on a skin-tempered steel sheet is essential for coating by vapor deposition and for applying a metallic coating that is as homogeneous as possible to the skin-tempered steel sheet.
  • the inventors have found that it is advantageous if the surface structure is embossed into the steel sheet starting from a surface of the steel sheet, the surface structure having a flank area which runs from the surface to a valley area, the flank area being perpendicular to the Steel sheet is formed with an angle, and the steel sheet is coated with a metallic coating that according to the invention the angle is formed between 20 ° and 85 ° and the coating is applied by vapor deposition.
  • a defined setting of the angle between the flank area and the perpendicular of the steel sheet can be used to influence a homogeneous deposition in a targeted manner, in particular by deliberate modeling of the flank area.
  • the skin-pass roller is designed in such a way that flank areas that are as flat as possible and run out as slowly as possible and in particular no steep or vertical flank areas, in particular in all directions, are pressed onto the surface of the steel sheet. Accordingly, bulging and/or undercuts in the (negative) skin-pass impression are essentially avoided, so that the deposit can be distributed without obstacles on the surface and in the skin-pass impression.
  • a deterministic surface structure is to be understood as meaning recurring surface structures which have a defined shape and/or design, cf. EP 2 892 663 B1 .
  • this also includes surfaces with a (quasi) stochastic appearance, which, however, are applied using a deterministic texturing process and are therefore composed of deterministic form elements.
  • Sheet steel is generally to be understood as meaning a flat steel product which can be provided in the form of sheet metal or in the form of blanks or in the form of strips.
  • the metallic coating can be zinc or aluminum based.
  • Base in this context means that more than 50% by weight of the coating consists of zinc or aluminum.
  • the coating can also only consist of zinc together with unavoidable impurities or also only of aluminum together with unavoidable impurities.
  • Other chemical elements such as magnesium, iron, silicon, manganese, nickel, chromium and/or zirconium can each be added individually or in combination in order to improve the properties of the coating.
  • a zinc-aluminum combination (along with unavoidable impurities) with or without other chemical elements is also possible conceivable.
  • high-melting coatings, especially those based on iron, can also be applied.
  • Coating by chemical vapor deposition is conventional and well known to those skilled in the art.
  • the surface structure has a flank area which runs from the surface to a valley area and is formed at an angle of between 30° and 85° to the vertical of the steel sheet.
  • the angle can particularly preferably be between 35° and 85°.
  • the valley and flank area (negative form) of the surface structure essentially corresponds to the surface (positive form) on a skin-pass roller, which forms or embosses the surface structure through a corresponding effect on the steel sheet.
  • the flank area surrounding and forming the surface structure, together with the valley area integrally connected to the flank area defines a closed volume of the surface structure stamped into the steel sheet by skin-pass rolling.
  • the closed volume the so-called empty volume, can contain a process medium to be applied, for example oil, for later processing using the forming process.
  • the geometric design (size and depth) of a deterministic surface structure (negative shape) on a skin-pass steel sheet depends in particular on how the corresponding geometric structure (positive shape) is/is designed on a skin-pass roll.
  • Laser texturing methods are preferably used in order to be able to set specific structures (positive shape) on the surface of a temper roll by removing material.
  • the targeted control of the energy, the pulse duration and the selection of a suitable wavelength of a laser beam acting on the surface of the temper roll can have a positive influence on the design of the structure(s). With high or higher pulse duration, the interaction time of the laser beam and skin-pass roll surface increases and more material can be removed from the surface of the skin-pass roll.
  • a pulse leaves an essentially circular crater on the surface of the skin-pass roller, which, if there are several craters, depicts the surface or area of the elevations on the steel sheet after the skin-pass process and thus the contact surface between the steel sheet and the skin-pass roller that gives the shape.
  • a reduction in the pulse duration affects the formation of a crater, in particular the diameter of the crater can be reduced.
  • By reducing the pulse duration in particular when using short or ultra-short pulse lasers, it is possible to set the geometric structure (positive shape) on the surface of a skin-pass roll in a targeted manner in order to texture a steel sheet surface in such a way that the flank area of the surface structure an angle of between 20° and 85° can be created for the tempered sheet steel.
  • any gradients (angles) of the flank area can be set in a targeted manner.
  • the steel sheet can be coated with a further metallic coating, which is arranged below the metallic coating applied by vapor deposition, and can thus be applied directly to the steel sheet.
  • the further metallic coating is applied by hot dip coating.
  • the further metallic coating is a zinc-based coating.
  • the further metallic coating can preferably contain additional elements such as aluminum with a content of up to 5% by weight and/or magnesium with a content of up to 5% by weight in the further metallic coating.
  • Sheet steel with a zinc-based coating has very good cathodic protection against corrosion, which has been used in automobile construction for years.
  • the coating additionally has magnesium with a content of at least 0.3% by weight, in particular at least 0.6% by weight, preferably at least 0.9% by weight.
  • Aluminum can be present as an alternative or in addition to magnesium with a content of at least 0.3 wt coated sheet steel, so that the positive corrosion properties are retained.
  • the thickness of the further metallic coating can be between 1 and 15 ⁇ m, in particular between 2 and 12 ⁇ m, preferably between 3 and 10 ⁇ m.
  • melt-exchange coating the steel sheets are first coated with a corresponding further metallic coating and then fed to skin-passing. Skin-passing takes place after the steel sheet has been hot-dip coated.
  • the steel sheet can be coated with a further metallic coating, which is arranged below the metallic coating applied by gas phase deposition, and can thus be applied directly to the steel sheet.
  • the further metallic coating is applied by electrolytic coating.
  • the thickness of the further metallic coating can be between 1 and 10 ⁇ m, in particular between 1.5 and 8 ⁇ m, preferably between 2 and 5 ⁇ m.
  • the steel sheet can first be skin-passed and then electrolytically coated. Depending on the thickness of the additional metallic coating, the angle in the flank area can essentially be retained even after the electrolytic coating.
  • first an electrolytic coating with subsequent skin-passing is conceivable.
  • the further metallic coating can be applied subsequently to the metallic coating already applied by gas phase deposition, so that, for example, the metallic coating applied to the steel sheet by gas phase deposition can act as a quasi "adhesion promoter" or "interface” for further metallic coatings in order to in particular to upgrade steel sheet surfaces that are difficult to wet, for example hot-dip coatable, for the application of the further metallic coating. Poorly wettable steel sheets are, for example, high-alloy steel materials that are familiar to those skilled in the art.
  • the further metallic coating, which is applied to the metallic coating by vapor deposition is preferably applied by hot dip coating.
  • the further metallic coating can also be applied by electrolytic coating.
  • the surface (positive shape) of the skin-pass roll forms a surface structure through the action of force on the surface of the steel sheet, which defines a valley and flank area (negative shape) and essentially corresponds to the surface (positive shape) of the skin-pass roll.
  • the skin-pass roller to form a deterministic surface structure can be processed using suitable means, for example using a laser, see also EP 2 892 663 B1 .
  • removal methods can also be used to adjust a surface on a skin-pass roller, for example machining processes with a geometrically defined or undefined cutting edge, chemical or electrochemical, optical or plasma-induced methods which are suitable for being able to implement a surface structure on a steel sheet to be skin-passed , which has an angle to the perpendicular of the surface of the steel sheet between 20 ° and 85 ° at least in the flank area.
  • tempered steel sheets (1) with a deterministic surface structure (2) are shown in schematic partial sectional views.
  • the steel sheets (1) which are provided in the form of sheets or preferably strips, are coated with a metallic coating (1.2), the metallic coating (1.2) being applied by vapor deposition in a suitable device.
  • the example shown shows a schematic of a physical vapor deposition (4), with appropriate coating material such as zinc, aluminum and the like being converted into the vapor phase (4.1) and in the form of a metallic coating (1.2) on the surface (1.1) of the steel sheet (1) separates, in particular condenses.
  • the difference between the statements in Figure 1a) and Figure 2a ) is that the sheet steel (1) in the version in Figure 2a ) with an angle ( ⁇ ) between 20° and 85° between flank area (2.3) and vertical (0) of the steel sheet (1) has been adjusted according to the invention.
  • the surface structure (2) is embossed into the steel sheet (1) starting from a surface (1.1) of the steel sheet (1), the surface structure (2) having a flank area (2.3) which, starting from the surface (1.1) to a Valley area (2.2) runs.
  • the flank area (2.3) and the valley area (2.2) are replaced by the corresponding area (positive shape) on the not-shown Tempering roller set.
  • the flank area (2.3) running around and forming the surface structure (2) defines, together with the valley area (2.2) integrally connected or connected to the flank area (2.3), a closed volume of the surface structure (2) embossed into the steel sheet (1) by skin-pass rolling.
  • the angle ( ⁇ ) is deliberately formed between 20° and 85°.
  • the angle ( ⁇ ) was set at approx. 50° and it is easy to see that there are no coating defects and that a tempered steel sheet (1) can be coated with a homogeneous metallic coating (1.2) by gas phase deposition, with an essentially flat transition between the valley area (2.2) and the surface (1.1) surrounding the valley areas (2.2) can be set essentially without undercuts and other disturbing obstacles, cf. Figure 2b ).
  • direction-independent deposition can be favored by the targeted setting of the deterministic surface structure (2).
  • (1.3) symbolically indicates a further metallic coating, which can be optionally applied, for example by hot-dip coating or by electrolytic coating before coating by gas-phase deposition, or alternatively can be optionally applied after coating by gas-phase deposition.
