摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung von Metalllegierungen. Das Verfahren ermöglicht die Herstellung von Metalllegierungen aus wenigstens zwei Metallen, die einen hohen Schmelzpunktunterscheid aufweisen. Dabei wird das höher schmelzende Metall zuerst geschmolzen und durch Wärmeübertragung das niedriger schmelzende Metall verzögert in Schmelze gebracht woraufhin sich die Metalle miteinander vermischen. Dadurch werden Metalllegierungen mit hoher Reinheit bei geringen Verdampfungsverlusten erhältlich gemacht, die insbesondere den Einsatz von verunreinigten Ausgangskomponenten wie recyceltem Metall ermöglichen.

Methods and apparatus are provided for igniting, modulating, and sustaining a plasma for various plasma processes and treatments. In one embodiment, a plasma is ignited by subjecting a gas in a multi-mode processing cavity to electromagnetic radiation having a frequency between about 1 MHz and about 333 GHz in the presence of a plasma catalyst, which may be passive or active. A passive plasma catalyst may include, for example, any object capable of inducing a plasma by deforming a local electric field. An active plasma catalyst can include any particle or high energy wave packet capable of transferring a sufficient amount of energy to a gaseous atom or molecule to remove at least one electron from the gaseous atom or molecule, in the presence of electromagnetic radiation.

Die vorliegende Erfindung betrifft ein Verfahren zur Plasmabehandlung in Hohlkörpern, insbesondere zur plasmachemischen Modifizierung von im Inneren von Hohlkörpern befindlichen Oberflächen. Bei dem Verfahren wird ein flexibler Hohlkörper bereitgestellt, der vor dem Verschließen unter Volumenkontraktion auf einen bestimmten Druck evakuiert wird. Dieser Druck wird so gewählt, daß der Hohlkörper unter reduziertem Außendruck in einer Plasmaprozeßkammer eine Volumenexpansion erfährt, bei der der Druck im Hohlkörper einen Wert erreicht, der bei Anlegen eines äußeren elektrischen Feldes eine Gasentladung im Hohlkörper zuläßt. Der auf diese Weise evakuiert und verschlossene Hohlkörper wird in eine Vakuumkammer gebracht, die derart evakuiert wird, daß sich im Hohlkörper die Voraussetzungen für das Zünden einer Gasentladung einstellen. Schließlich wird die Gasentladung innerhalb des Hohlkörpers durch Anlegen eines elektrischen Feldes gezündet. Mit dem erfindungsgemäßen Verfahren läßt sich auf einfache und vorteilhafte Weise die Plasmabehandlung im Inneren von Hohlkörpern erreichen, ohne daß zusätzliche Modifikationen an bestehenden Plasmaanlagen erforderlich wären.
摘要:
The invention provides a gas barrier film with low deterioration in the gas barrier property before and after high-temperature hot water treatment. The gas barrier film has a gas barrier coating film, formed as a composite film comprising a network structure having a mesh structure with Si-O-Si bonds as the basic lattice and a water-soluble polymer crystallized as microcrystals, incorporated into the mesh of the network structure, wherein a barrier coating agent, obtained by mixing a condensate solution of an alkoxysilane hydrolysate prepared as a mixed solution in which the proportion of bonded states of the silicon atoms of the condensate with Q1 and Q2 structures is at least 60% of the total silicon atoms, with a crystalline water-soluble polymer, is coated on a base material film, either after forming or without forming an aluminum oxide vapor deposition film, to form a coating layer.
