Abstract: A process for producing a wear-resistant cylinder bearing surface includes rotating a laser about its longitudinal axis and simultaneously advancing the laser in a direction of the longitudinal axis which is coaxial with a cylinder of a crankcase. A powdery material is fed through the laser and a jet of the powdery material is directed toward the cylinder bearing surface. A laser beam is deflected to an impact region where the jet of the powdery material impinges on the cylinder bearing surface. The jet of the powdery material passes through the laser beam. The laser beam at least partially melts the impact region before the powdery material impinges on the impact region. A device for producing wear-resistant surfaces is also provided.

Abstract: A wear-resistant surface is formed on a component formed of an AlSi alloy by using a thermal spraying or a laser beam treatment. A thermally conductive device is brought into a thermally conductive contact with the component so that the thermally conductive device touches the component during the step of forming the wear-resistant surface. The thermally conductive device is actively cooled.

Abstract: A method of treating a surface of a component includes performing a thermal spraying in a given treatment zone on a surface of a component. A laser surface treatment is performed in front of the given treatment zone, at the given treatment zone and/or behind the given treatment zone. The thermal spraying and the laser surface treatment are performed in a single processing step. A device for treating a component surface includes a plasma torch for providing a plasma jet and a laser for providing a laser beam. The plasma torch and the laser are configured to sweep the plasma jet and the laser beam over a component surface and to perform a surface treatment in a single pass.

Abstract: System for packaging integrated circuits, especially sensors, in a housing, which also comprises multicontact bondings, especially hybrid ICs for three-dimensional arrangement of modules, wherein sensors (4, 5) are arranged at an angle in relation to one another on the base plate or the substrate (1). The sensors are contained in the single housing together with contact pins (pins) (2), and are connected in one plane by automatic bonding.
