Definitions

  • the invention relates to a method according to the preamble of the claim 1 and a coated object according to the preamble of Claim 4.
  • JP 08 173321 describes a kitchen vessel with a layer of "fluorocarbon resin” or “fluororubber” in which ultrafine diamonds were embedded.
  • the diamonds were embedded in a non-stick layer made of Teflon or related material.
  • JP 07 067784 describes a coated kitchen vessel with an aluminum base described. One was directly on the surface of the base body a flame spraying applied aluminum oxide layer, which from a "fluoro" layer was covered with embedded “ultra-super-fine” diamond particles.
  • JP 59 166670 is a tool with a diamond containing coating mentioned.
  • This coating could be made of carbides, Nitrides, carbonitrides and carboxynitrides of groups IVa, Va and VIa, made of silicon or boron.
  • the diamonds were "vapor-phase-synthesis", so one CVD process generated.
  • the object of the invention is to produce an object made essentially of aluminum or to provide or create an aluminum alloy with a coating, wherein the coating is preferably hard and the good thermal conductivity of the article supported, so that this is preferred as a heater (iron, ...), kitchen appliance for roasting, baking, etc., and on other occasions where uniform heating over the largest possible surface area is desired or is required.
  • a correspondingly manufactured object is in claim 4
  • Preferred embodiments are claimed in claims 2, 3 and 5 to 14.
  • a coating appropriately pretreated surface in particular essentially Aluminum or an aluminum alloy existing object becomes a coating applied, in which diamonds are embedded.
  • the diamonds in particular care due to their extremely good thermal conductivity for a good heat transfer from one Good lying on the coating to the object, which is also a good heat conductor. This ensures uniform heating of the goods.
  • this coating is used to support the mechanical Hardness of the embedded diamonds as a hard layer consisting essentially of an aluminum oxide / titanium dioxide mixed layer muster.
  • Aluminum oxide and titanium dioxide in nature Known as sapphire or rutile, they are very hard. This great hardness is in the Aluminum oxide / titanium dioxide mixture then through the embedded diamond crystals Diamond not only has the highest known hardness, but also that best (largest) known thermal conductivity.
  • the hard aluminum oxide / titanium dioxide mixed layer as a so-called binder for the even harder diamond crystals a very hard coating, which has a very good thermal conductivity.
  • the object to be coated from a good heat-conducting material namely in essential (negligible impurities are always present) aluminum or an aluminum alloy such a coated object can anywhere wherever possible, the most uniform temperature possible over a large area.
  • the layer containing diamonds is reduced compared to known layers, which also have an anti-adhesive effect, the "thermal barrier" resulting from this layer is essential.
  • the invention is therefore a kitchen device (e.g. frying pan) used.
  • the mixed layer can be provided with non-stick layers, which further improves its use as a “non-sticky” pan.
  • Non-stick coatings generally have a dark color. If a mixed layer with 80 to 40 percent by weight aluminum oxide (Al 2 O 3 ) and 20 to 60 percent by weight titanium dioxide (TiO 2 ), preferably with about 60% aluminum oxide and 40% titanium dioxide, is applied, it is dark. A slight injury to a non-stick layer of PTFE (polytetrafluoroethylene) applied over the mixed layer is therefore no longer visible.
  • PTFE polytetrafluoroethylene
  • the mixed layer can be arranged through a fluorosilane layer, in which diamond crystals are also preferably embedded, in their hardness behavior and in their flat thermal conductivity and their non-stick behavior can still be improved.
  • This layer can then also be pigmented, in particular darkly pigmented which also causes minor injuries to the non-stick coating above, which do not disturb their non-stick effect, are hardly visible anymore.
  • the coating 1 shown in the single figure is applied to an aluminum pan bottom 3 as an object.
  • the surface 5 of the pan base 3 is pretreated for the subsequent coating.
  • the surface 5 is degreased and sandblasted with corundum powder.
  • the corundum powder has fine grains to which coarse grains are mixed.
  • the coarse grains produce a roughness of approximately one hundred to two hundred micrometers on the surface 5 to be coated.
  • This coarsely roughened surface structure is overlaid with a finer roughness by fine grains of about ten to thirty micrometers.
  • the whole object (pan) is used in an oven at a temperature below 600 ° C. A temperature of 450 ° C. is preferably selected.
  • a mixture with 80 to 40 percent by weight of aluminum oxide (Al 2 O 3 ) and 20 to 60 percent by weight of titanium dioxide (TiO 2 ) is applied.
  • Al 2 O 3 aluminum oxide
  • TiO 2 titanium dioxide
  • about sixty percent by weight of aluminum oxide and forty percent by weight of titanium dioxide with an admixture of five to ten percent by weight of aluminum fluoride (AlF 3 ) are applied as a homogeneous mixture in a plasma spraying process as a thermal spraying process.
  • AlF 3 aluminum fluoride
  • aluminum fluoride is not mandatory; other non-stick materials can also be used. However, it is important to ensure compatibility with the aluminum oxide-titanium dioxide mixture.
  • the material used must also remain under the thermal conditions of plasma spraying. In plasma spraying, diamond crystals are added, which have a diameter between 0.5 ⁇ m and 10 ⁇ m.
  • the aluminum oxide-titanium dioxide-aluminum fluoride mixture with embedded diamond crystals is sprayed onto the surface 5 as a mixed layer 7 up to a layer thickness of 50 ⁇ m to 150 ⁇ m. The applied mixed layer 7 appears black.
  • the diamond crystals must be mixed in such a way that they have no temperature exposed to temperatures above 900 ° C. At 900 ° C, diamond can transform into graphite or burn when exposed to oxygen. Of these 900 ° C should a sufficient temperature-related distance should be kept.
  • the aluminum oxide as a relatively inexpensive material, gives the layer 7 the necessary hardness, while titanium dioxide gives this layer 7 the ductility and the dark or black color.
  • the ductility of the titanium dioxide gives the coating good resistance to large temperature fluctuations; as they occur with frying pans.
  • a further layer 9 of fluorosilane likewise with embedded diamond crystals with a diameter of 0.5 ⁇ m to 10 ⁇ m, can be applied to the mixed layer 7 as a suspension.
  • the suspension is preferably admixed with a pigment which is used to match the color of the mixing layer 7 .
  • the article is then heated in an oven in several stages (100 ° C, 250 ° C, 400 ° C) to 400 ° C to 430 ° C and held at the final temperature for about ten to fifteen minutes.
  • This layer 9 is not mandatory.
  • the non-stick effect of the coating is also given without this layer 9 ; however, it is still improved by this.
  • a carbon black pigment for example, is used as the pigment.
  • PTFE polytetrafluoroethylene
  • This suspension also penetrates into the remaining roughness and into the pores.
  • a heating program analogous to that of layer 9 is carried out.
  • the fact that the final temperature is held here for ten to fifteen minutes means that the PTFE is burned in.
  • the softening temperature of the PTFE is 360 ° C. The temperature of the object is thus clearly above this temperature during the baking, so that the suspension particles are sintered into a tough and elastic layer.
  • the sintering together creates an elastic PTFE cover layer 11 which, with a layer thickness of two to ten micrometers, conforms well to the remaining roughness of the layer 9 underneath.
  • the coating 1 described here is very well non-stick to food to be heated (roasted) lying on it and also resistant to scratching with good "heat distribution" over the pan bottom. Should the top PTFE layer 11 nevertheless be scratched, this scratching is not visible due to the color adaptation of the layer 9 to the color of the mixed layer 7 . The anti-adhesive property is hardly affected by this, since the layer 9 is also “anti-adhesive”.
  • nitrides, carbides, oxynitrides or carboxynitrides or several elements from chemical groups IVb to Vlb, of aluminum, of Nickel or silicon or mixtures thereof can be used.
  • group IVb include titanium (Ti), zircon (Zr) and hafnium (Hf).
  • Group Vb includes vanadium (V), Niobium (Nb) and tantalum (Ta).
  • the Vlb group includes chromium (Cr), molybdenum (Mo) and tungsten (W).
  • the mixture described above has proven to be particularly advantageous.
  • the layer 9 can also be applied and, after it has dried, the layer 11 immediately, which then, as described above, both increase step-wise or approximately continuously be heated.
  • a cover layer made of PTFE instead of a cover layer made of PTFE, a PFA layer (Perfluoralcyd) or an FEP layer (fluoroethylene propylene) and related materials be used.
  • a PFA layer Perfluoralcyd
  • an FEP layer fluoroethylene propylene
  • the object made of aluminum or an aluminum alloy to manufacture it can also be made of stainless steel or iron.
  • aluminum or its alloys have the advantage of a good one Thermal conductivity.
  • Objects made of copper can also be coated accordingly become; however, care must be taken to ensure that there is no oxidation of the Copper surface occurs.
