The invention relates to a method for producing an electrode (E) for an electrochemical cell, in particular for a lithium cell. In order to produce a homogeneous mixture allowing the time-saving, cost-effective production, for example by dry coating, of an electrode (E) with improved properties and/or with a layer thickness significantly greater than 100 &#x3bc;m, for example for vehicle batteries, in particular for electric and/or hybrid vehicles, in said method at least one binder (B) and at least one particulate fibrillation auxiliary agent (F) are mixed in a mixing process with a high shear load, the at least one binder (B) being fibrillated (fB), and at least one electrode component (E) is then added to the at least one fibrillated binder (B) in a mixing process with a low shear load. The invention also relates to an electrode (E) produced in this manner and to an electrochemical cell equipped with an electrode (E) of this type.

Electrode production method by binder fibrillation using a particulate fibrillation auxiliary agent

A method for producing a component, in particular a rotor wheel, includes positioning a main body, a fusion-weldable attachment layer, and a barrier layer. The main body has a first alloy in an attachment region. The fusion-weldable attachment layer is positioned in the attachment region of the main body and has a second alloy which differs from the first alloy. The barrier layer is positioned between the main body and the fusion-weldable attachment layer. The barrier layer is configured to prevent a reaction of the first alloy of the main body with the second alloy of the fusion-weldable attachment layer during a thermal treatment. The method further includes heating the main body, the barrier layer, and the fusion-weldable attachment layer to connect the main body, the barrier layer, and the fusion-weldable attachment layer to one another.

The highly electrode-erosion-resistant region () comprises an alloy which has at least the elements iridium and nickel.

Method of manufacturing a spark plug for an internal combustion engine

The present invention relates to a method of fabrication and a product, which forms a composite body made of metal and a porous ceramic blank, which adjoins the metallic portion and is infiltrated by the metal, wherein a gradient in properties across the composite portion of the composite body is formed by a heat treatment that reduces some of the oxides across the thickness of the porous ceramic blank. In one embodiment, a gradient from substantial chemical reaction to incomplete chemical reaction of the reducible oxides of the blank with the infiltrated metal is formed inside the composite portion.

A spark plug having a ceramic insulator, which contains a precious-metal center electrode in a cylindrical, axial opening, at the end on the side of the combustion chamber. A contact pin is arranged in the cylindrical opening, downstream from the precious-metal center electrode, in the direction of the insulator end away from the combustion chamber. To reduce corrosion, the surface of the contact pin is provided with a layer of one or more metal aluminides.
