Abstract
Geschichteter Festkörper, dessen Schutzschicht an einer Außenfläche in zu dieser senkrechten Richtung eine Dimension hat, die ein Bruchteil von der kleinsten Dimension des Festkörpers ist, dadurch gekennzeichnet, dass die Schutzschicht Metalloxide oder Silikate aufweist, deren metallische Komponenten leicht aufdampfbar sind, wobei die zugehörigen Oxide oder Silikate hart sind.Layered solid, the protective layer of which on an outer surface has a dimension in the direction perpendicular to this which is a fraction of the smallest dimension of the solid, characterized in that the protective layer has metal oxides or silicates, the metallic components of which are easily vapor-deposited, the associated oxides or silicates are hard.
Description
Die Erfindung betrifft einen geschichteten Festkörper, dessen Außenschicht an einer Außenfläche eine Dicke von einem Bruchteil der kleinsten Dimension des Festkörpers beträgt.The invention relates to a layered solid whose outer layer is on an outer surface of a thickness of a fraction of the smallest dimension of the solid.
Schutzbeschichtungen sind zahlreiche bekannt. Insbesondere bei Glas besteht das Bedürfnis, dass die Durchsichtigkeit desselben und die optische Qualität nicht eingeschränkt werden, auch nicht über eine längere Dauer.Protective coatings are well known. Especially in glass there is a need that the transparency of the same and the optical quality are not limited, even over a longer period.
Die Notwendigkeit, die Fenster häufig zu putzen, rührt davon her, dass die Oberfläche von Glas angegriffen wird durch in der Atmosphäre enthaltenen Wasserdampf und Kohlensäure, die besonders auf das CaO und Na2O des Oxidgemisches einwirken und CaOH und NaCO3 bilden, die die Oberfläche des Glases trüben.The need to frequently brush the windows is due to the fact that the surface of glass is attacked by water vapor and carbonic acid contained in the atmosphere, which act especially on the CaO and Na 2 O of the oxide mixture and form CaOH and NaCO 3 , which are the Surface of the glass tarnish.
Die vorliegende Erfindung bezweckt, die Struktur, die sich an der Oberfläche des geschmolzenen Glases durch Oberflächenspannung ausbildet, gegen Dampf und Kohlensäure unempfindlich zu machen. Damit wäre dann auch das Blindwerden von Glas verhindert.The object of the present invention is to make the structure formed on the surface of the molten glass by surface tension insensitive to vapor and carbonic acid. This would also prevent the blindness of glass.
Erfindungsgemäß wird daher empfohlen, die Außenfläche des Festkörpers, d. h. die Oxidverbindungen, die verwittern können, mit einer (evtl. zusätzlich undurchsichtigen bzw. lichtabsorbierenden) Schicht eines geeigneten Metalles zu bedecken, z. B. Aluminium, und sie mit Wärme zu behandeln, damit sie von der Atmospähre nicht mehr angegriffen werden kann.According to the invention, it is therefore recommended that the outer surface of the solid, d. H. the oxide compounds that can weather with a (possibly additionally opaque or light absorbing) layer of a suitable metal to cover, for. For example, aluminum, and treat them with heat, so that they can no longer be attacked by the atmosphere.
Eine dünne Aluminiumschicht kann sich schon bei Raumtemperatur durch den Sauerstoff der Luft in ein Oxid umwandeln, das erst bei sehr hoher Temperatur schmilzt. Das Glas wird mit einer sehr dünnen Metallschicht bedampft oder sie wird auf das Glas aufgestäubt und schützt es dann ebenso gegen Angriffe der Atmospähre und gegen andere chemische Einflüsse (wie z. B. Aluminium von einer sich auf seiner Oberfläche bildenden gasdichten Oxidsperrschicht geschützt wird.)Even at room temperature, a thin layer of aluminum can be converted by the oxygen in the air into an oxide that melts only at very high temperatures. The glass is steamed with a very thin layer of metal or it is dusted on the glass and then protects it as well against attacks of the atmosphere and against other chemical influences (such as aluminum is protected by a gas-tight oxide barrier layer forming on its surface.)
Für solche dünne Beschichtung eignen sich alle Metalle, die leicht aufdampfbar sind und harte Oxide oder Silikate bilden, wie Al, Ba, Cr, Fe, In, Co, Cu, Mg, Ni, Si, Ti oder Sn.For such a thin coating, all metals which are readily vapor-deposited and form hard oxides or silicates, such as Al, Ba, Cr, Fe, In, Co, Cu, Mg, Ni, Si, Ti or Sn are suitable.
Die beschriebene Oberflächenbehandlung von Gläsern mit einer Metallschicht und deren Umwandlung in eine Schutzschicht wird auch als Methode zur Steigerung ihrer Festigkeit vorgeschlagen. Durch die Bedeckung mit Metall, vorzugsweise Ti, und dessen Umwandlung erfolgt eine Zunahme des Volumens und die Oberfläche wird verdichtet. Infolgedessen entstehen bei stärkeren Beanspruchungen weder Mikrorisse noch Oberflächenfehler. Das beschriebene Verfahren ist auch besonders zur Erhöhung von Festigkeit und Beständigkeit von Glasfasern im Verbande von Kunststoffen vorteilhaft.The described surface treatment of glasses with a metal layer and their conversion into a protective layer is also proposed as a method for increasing their strength. By covering with metal, preferably Ti, and converting it, the volume increases and the surface is densified. As a result, there are no microcracks or surface defects under heavier loads. The method described is also particularly advantageous for increasing the strength and durability of glass fibers in the association of plastics.
Bei sehr glatter Auflenfläche kann eine Dicke der Schutzschicht von einigen nm (X × 10–9 m; 1 < X < 20) genügen. Insbesondere gilt dies, wenn eine (reine chemische) Korrosion die Außenfläche angreift.At very smooth Auflenfläche a thickness of the protective layer of a few nm (X × 10 -9 m; 1 <X <20) meet. In particular, this applies if (pure chemical) corrosion attacks the outer surface.
Für die optische Anwendbarkeit sollte die Dicke der Schutzschicht auf jeden Fall unter 100–300 nm sein.For optical applicability, the thickness of the protective layer should be below 100-300 nm in any case.
Diese Schichtdicke könnte auch für den Fall (evtl. zusätzlicher) mechanischer Aggression ausreichende Stabilität besitzen.This layer thickness could also have sufficient stability for the case (possibly additional) mechanical aggression.
