Definitions

  • the invention relates to a method for producing a component, in particular a sanitary component, with a metallic surface layer having at least two surface portions with a different appearance to form a label and / or a decorative pattern.
  • the invention relates to a component which is produced by the aforementioned method.
  • a method for manufacturing a component in which a surface layer of the component is processed in order to apply a lettering and / or a decorative pattern.
  • the component essentially consists of a carrier, an intermediate layer and a surface layer, wherein the surface layer is formed from a chromium layer. So the surface layer for decoration or labeling purposes is formed at least two colors, is burned in a surface area, which is to have a different color to the chromium layer, by means of a laser beam a well. This depression is then filled with a color.
  • a disadvantage of the known method is that the design of a relatively large colored surface area, the quality of the label or the decorative pattern suffers when it is exposed to relatively severe environmental conditions or strong external stress.
  • Object of the present invention is therefore to provide a method for producing a component or a component such that a long-term stable, abrasion-resistant and color-contrasting lettering or decorative pattern is ensured in a continuous metallic surface coating.
  • the invention in connection with the preamble of claim 1, characterized in that a predetermined masking color is applied by means of printing, wherein a free surface of the surface layer or an intermediate layer to be absorbed by a color-deposited means of the masking color is recessed, that the surface layer or the intermediate layer is removed in the free region to form a depression by electroplating or with a color-deposited agent that is introduced as a color-deposited agent, a metal layer in the exposed recess or the free area and that the masking paint from the surface layer or the Interlayer is removed.
  • the particular advantage of the invention is that a multi-colored metallic surface layer is achieved in manufacturing technology simple manner, which has a long life with relatively strong external stress.
  • a masking ink by means of printing, preferably screen printing, a mask can be produced which leads to a relatively high resolution in the production of the label or to an improved Grenzsauberkeit in the transition region between the one metallic region of the surface layer and the color remodeled other metallic Area of the surface layer leads.
  • the corresponding metal layer in the region left clear by the mask can be easily removed by etching.
  • a color-different metal layer can then be introduced into the recesses of the free surface area, so that after removal of the masking color, a continuous and flat multicolored metallic surface layer is formed.
  • the masking ink can be applied to a metallic surface layer or a metallic intermediate layer.
  • the exposed area may be left blank by means of an additional metal material or replaced by previously removing the exposed layer with another metal layer.
  • a matting layer can be applied so that, after subsequent chromium plating of the entire surface, on the one hand, a shiny chrome color effect and, on the other hand, a matt chrome color effect are achieved.
  • the released chromium layer in the free surface region of the component is removed by means of an acid, so that the coloring of the metallic surface layer can be effected by means of electroplating.
  • the component according to the invention according to claim 7 characterized in that a first surface layer of a first metal material and a second surface layer of a second metal material are arranged flush with each other to form a flat or slightly curved top.
  • the particular advantage of the component according to the invention is that a multicolored metallic surface layer can be produced in a simple manner, which has a high-quality optical appearance as well as permanent and flush transitions between the differently colored surface areas.
  • the inventive method for producing a component 1 is in the FIGS. 2 to 5 shown in more detail.
  • the component 1 may be formed, for example, as a functional body in the sanitary area, for example as a valve or in the automotive sector as a handle part.
  • the production of a block-shaped component 1 is described, which has a flat top 2, which is formed from a two-color surface layer.
  • a first surface layer 3 is formed of a first metal material, preferably chromium.
  • a second surface layer 4 which is arranged adjacent and flush with the first surface layer 3, consists of a metal layer of a different color to the first surface layer 3, for example of a gold, platinum, palladium layer.
  • the second surface layer 4 is formed relatively rich in contrast to the first surface layer 3, so that a caption "HDO" of the component 1 can be formed.
  • a decoration pattern can be formed, which also has a relatively good Grenzsauberkeit in the transition regions between the first surface layer 3 and the second surface layer 4.
  • the top 2 is flat or slightly curved.
  • a semifinished product 5 for example a semifinished product 5 produced by die-casting, is formed in a first step.
  • the semifinished product 5 has as support 8 a zinc material (zinc alloy) on which a copper layer 9, a nickel layer 10 and the continuous surface layer 3 are applied in succession by electroplating.
  • the semifinished product 5 can optionally be polished and / or ground.
  • a masking ink 6 is applied by means of screen printing, with a partial area 7 of the upper side 2 of the semifinished product 5 being recessed.
  • the printing ink be printed with a wiper-like tool (squeegee) through a fine-meshed textile fabric on the material to be printed. This results in a relatively firm connection between the masking ink 6 and the upper side 2 of the semifinished product 5.
  • the chromium layer 3 can also be deposited directly on the carrier 8 by electroplating.
  • a further method step according to FIG. 3 For example, in a plating process - immersing the semifinished product 5 in a hydrochloric acid bath - the first surface layer 3 in the partial area 7 (the free surface area not covered by the masking ink 6) is removed so that the underlying nickel layer 10 is exposed. Thus, a recess 11 is formed in the surface layer 3 which is in alignment with the recess 13 of the masking ink layer 6.
  • the semifinished product 5 is subjected to a washing process, so that the uncovered surfaces in the subregion 7 have the required cleanliness for the further working step.
  • a metal layer (second surface layer 4) of a different color to the chromium layer 3 is introduced, which serves as an agent deposited in color to the adjacent chromium layer 3.
  • this metal layer 4 may consist of a gold, platinum or palladium material.
  • the masking ink 6 is removed, so that a flush top 2 with two different color surface layers 3 and 4 are exposed. How out FIG. 5 can be seen, both the top 2 of the component 1 and a flat side 12 of the top 2 facing carrier 8 is flat.
  • a surface layer 3 ' may also be formed from a platinum material.
  • a gold material can be applied in the free region 7 as second surface layer 4 'in a further step.
  • a two-color surface layer of the component 5 ' is likewise formed.
  • the surface layer 3, 4 may be formed by any metal / metal alloy layer, which is preferably not galvanisable.
  • any metal / metal alloy layer which is preferably not galvanisable.
  • color combinations of bronze / nickel, nickel / palladium, palladium / gold, platinum / gold can be formed.
  • an intermediate layer 30 may be partially coated with the masking ink 6.
  • An exposed surface area 31 of the semifinished product may be provided with a matting layer 33 are provided, so that after subsequent removal of the masking paint 6 and full-surface application of a chromium layer 3 different color appearing surface areas 34 and 35 are formed.
  • the first surface area 34 has a glossy chrome color impression and the second surface area has a matt chrome color impression. For reasons of simplification, is in FIG. 7 shown in the finished state no longer existing masking paint 6.
