摘要:
A joining component, for axial joining to a workpiece, comprises a base body composed of thermoplastic material and including a holding section and a flange section, with a joining surface including both a portion of the flange section and a metal section which can be heated inductively. The metal section is in this case integrated in the flange section.
摘要:
The invention relates to a method for axial joining of a hybrid joining component to a workpiece, wherein the joining component has a thermoplastic joining section and a metal section which can be heated, having the following steps: moving the joining component into contact with a surface of the workpiece; heating of the metal section such that the joining section at least partially melts; ending the heating of the metal section such that the joining component makes a force-fitting, interlocking and/or integral connection with the surface of the workpiece. In this case, the joining component is held with a regulated force and/or in a regulated position with respect to the workpiece at least during the heating of the metal section, in such a manner that the joining component can be joined to the surface of the workpiece without any opposing support.

The invention relates to noncorrosive auxiliaries for soldering aluminium and for upgrading aluminium alloys based on alkali metal fluoroaluminates, their preparation and their use. According to the invention, the noncorrosive auxiliaries contain metallates. To form the metallates, metal compounds of the elements of main groups 2 to 5 of the PTE or of the transition elements in the form of their salts or oxides are used as reactants. In particular, their halides, nitrates, carbonates, sulphates, phosphates, borates, hexafluorosilicates or oxides, for example, are used. According to the invention, the metal compounds are introduced into the reaction mixture of hydrofluoric acid and/or hydrated alumina and/or alkali metal compound, with the point in time when the metal compound is added being able to be varied as a function of the desired degree of functionalization of the surface.

摘要:
An advanced process control (APC) architecture comprising a process model that incorporates a target offset term is provided. The APC architecture may be applied to a so-called develop inspect critical dimension (DICD) model using the target offset term to correct at least one exposure parameter on the occurrence of an abrupt event. A corresponding event may, for example, concern a modified reflectivity of processed substrates, for example due to a rework of substrates covered by amorphous carbon material.
摘要:
Fluxing agents comprising potassium fluorostannate and/or cesium fluorostannate which can be used for brazing or soldering components of aluminum or of an aluminum alloy, even by solderless brazing or soldering. Conventional fluxing agents or other fluorometallates, such as alkali metal fluorozincates and/or alkali metal fluorosilicates, can also be added to the fluorostannate-containing fluxing agent. The fluxing agents of the invention can be applied by either dry or wet fluxing methods.
摘要:
Components composed of aluminum or an aluminum alloy with a coating comprising an aluminum-silicon alloy deposited thereon by applying an alkali metal fluorosilicate and heating the resulting treated material. The alloy layer is effectively protected against re-oxidation by a non-corrosive, alkali metal fluoroaluminate layer (e.g. a potassium fluoroaluminate layer) which forms simultaneously.
摘要:
Aluminum parts, e.g., heat exchangers, with improved resistance towards corrosion caused by contact with stationary water or aqueous compositions such as cooling water can be obtained by addition of Li compounds in specific amounts to the flux used for brazing the parts. LiF and especially Li fluoroaluminates are very suitable. The flux and the Li salt can be dispersed in water or an aqueous composition separately.
