Definitions
- the invention relates to an object with a coated surface, the
- Coating either consists of metal or is formed by a metal coating with a conversion layer.
- the invention further relates to a method for producing such an object.
- Objects made of metal would oxidize (rust) in the untreated state and thus unsuitable for use and unsightly.
- Numerous methods are therefore known by which the surface of the metal objects is treated or coated. This changes the surface condition so that corrosion can be avoided or delayed. This also changes the color of the metal object.
- These processes include the electroplating processes, chemical processes and oxidation processes, such as the anodization of aluminum.
- Coatings are generally intended to change the physical or chemical surface properties of materials in a favorable sense, be it that they should only be given metallic shine for decorative purposes, or that they have technically important properties such as solderability, electrical conductivity, Resistance to abrasion and wear, corrosion resistance, etc. or a combination of these properties must be imparted.
- the metal layers can be treated chemically.
- a passivation solution e.g. Can contain Cr EH or Cr VI
- the metal layers are made further corrosion-resistant.
- Coating type of this conversion layer different surface colors appear: blue, yellow, olive and black, which are also associated with different properties.
- Chromated zinc forms e.g. a colorable layer that can also be used for identification.
- the anodic oxidation consists in an electrical treatment of aluminum in an acid bath, which anodizes an oxide layer.
- the surfaces can still be sealed or painted with an organic polymer layer.
- Numerous other coating processes are also known, such as vacuum evaporation, cathodic and anodic dip coating, etc.
- Cathodic deposition of metals and dispersed solids for the production of composite materials is also known.
- powdered SiC dispersed in the solution so that it coexists with the metal, e.g. Nickel, can deposit on the surface.
- the metal e.g. Nickel
- SiC in particular causes a higher degree of hardness Surface.
- dyes or self-lubricating components can also be dispersed in the solution.
- wear protection layers are e.g. in the case of uniform tools or injection molding tools, by applying an electrodeposited intermediate layer under the actual protective layer.
- the intermediate layer contains microcapsules that are filled with fluorescent substances. Special sensors detect these substances as soon as they are ablated or the like. are released and trigger a signal.
- the invention has for its object to improve the visibility of metal objects in the dark.
- the object is achieved in that the surface contains visible fluorescent or phosphorescent material. This makes them shine
- the objects with fluorescent material shine when illuminated with light of certain wavelengths.
- the coated surface preferably contains nickel or zinc.
- the coating can then be applied by means of an electroplating process.
- the fluorescent or phosphorescent material can be in shape of pigments, for example based on aluminum, can be introduced into the electrolyte solution. The pigments are then stored in the surface coating during the treatment.
- a microporous or microcracked layer can be applied to a galvanically applied layer
- Chrome layer or noble metal layer from e.g. Gold or silver can be applied galvanically.
- the fluorescent or phosphorescent pigments are then visible through the micropores or microcracks.
- Conversion layer containing substances are applied. This conversion layer is usually applied chemically. Here, too, the pigments are introduced into the chemical solution and are stored in the coating.
- the conversion layer can contain microcracks, micropores or the like, through which the phosphor is visible.
- the coated surface can comprise the oxide of this metal, which is produced electrically.
- the anodization of metals such as aluminum, titanium or magnesium is particularly suitable for this.
- the pigments are introduced into the solution during the oxidation process or after the oxidation process and are stored in the coating. The layer is then sealed.
- the coating is carried out by vacuum evaporation of the object.
- Embodiments of the invention are the subject of the dependent claims. Some exemplary embodiments of the invention are described below. Description of the embodiments
- a metal object is chromated.
- the object is first cleaned and degreased so that it is free of grease and oxide.
- anodic degreasing is finally carried out in an electrolytic degreasing bath, pickled in dilute hydrochloric acid (1:10) and then galvanized.
- the galvanizing is done galvanically in a zinc solution. After the galvanizing, the goods are rinsed and before the actual one
- the passivation solution contains chromium (I ⁇ I) chloride and sodium nitrate (NaNO 3 ).
- the object At room temperature (20 ° C) the object is placed in the chromate solution for an exposure time between 60 and 120 seconds. Depending on the type of immersion of the object, a drum rotation of 6 to 12 revolutions per minute or a goods movement of 3-4 m per minute is required. However, the solution can also be kept in motion by blowing in air at 2 to 10 m 3 per hour and m 2 bath surface. Pigments of a fluorescent material are finely dispersed in the bath. These pigments, like the conversion layer, attach to the object and thus form a fluorescent surface coating of the object.
- a brass object is coated with nickel.
- the object is also cleaned and degreased.
- the object is then immersed as a cathode in a nickel electrolyte.
- a voltage of approximately 4 V is applied. This leads to the deposition of a nickel layer on the brass.
- the phosphorescent pigments contained in the bath are embedded in the layer of nickel, causing the layer to glow in the dark.
- the invention can be used as a function aid, for example for door handles, lock cylinders, openings for emergency exits or signs for emergency exits. It can also be used as decoration, for example in discotheques, for the housing of mobile telephones and the like.
