Abstract: A method of welding a wear layer onto a parent material, wherein a welding current is applied to a first wire electrode and to at least one second wire electrode. The first wire electrode and at least one second wire electrode are continuously fed to the parent material for producing a common weld pool. Metal powder and welding powder are fed to the weld pool. The wire electrodes are flux-cored wire electrodes, having a core and a covered electrode. The flux-cored wire electrodes have a higher alloy than a weld deposit analysis of the wear layer to be welded on the parent material. The covered electrode of the flux-cored wire electrodes includes an alloy, which has magnetization properties suitable for adhesion of the metal powder.

Abstract: The invention relates to a microelectromechanical system with an electromechanical microswitch for switching an electrical signal in particular a radio frequency signal, in particular in a GHz range, comprising a multi-level conductive path layer stack arranged on a substrate, wherein conductive paths of the multi-level conductive path layer stack arranged in different conductive levels are insulated from one another through electrically insulating layers and electrically connected with one another through via contacts, an electromechanical switch which is integrated in a recess of the multi-level conductive path layer stack and which includes a contact pivot, an opposite contact and at least one drive electrode for the contact pivot, wherein the contact pivot, the opposite contact and the at least one drive electrode respectively form a portion of a conductive level of the multi-level layer stack.

Abstract: A method for producing a MEMS component including the steps of simultaneously embedding structure elements during producing the multi-level conductive path layer stack which structure elements are to be subsequently exposed, subsequently producing a recess that extends from a substrate backside to the multi-level conductive path layer stack, exposing the micromechanical structure elements in the multi-level conductive path layer stack through the recess. In order to increase process precision a reference mask for defining a lateral position or a lateral extension of the micromechanical structure elements to be exposed is produced, wherein the reference mask is either arranged on the substrate front side between the substrate and the multi-level conductive path layer stack or in a layer of the multi-level conductive path layer stack which layer is more proximal to the substrate than the structure element to be exposed.
