Abstract: The invention relates to a method for coating cavity walls, in particular cylinder bores of engine blocks. In the method, a coating is applied to a cavity wall using a coating lance. In addition, a cavity diameter is measured using a measuring apparatus. According to the invention, the method is characterized in that at least a plurality of diameter values of a first cavity are measured at different heights of the first cavity using the measuring apparatus, and in that a coating of variable thickness is applied to a wall of the first or a second cavity using the coaling lance, the thickness of said coating of variable thickness being dependent on the determined diameter values. The invention additionally describes a corresponding coating system.

Abstract: The invention relates to a painting facility and a method for painting a workpiece, wherein, in a painting station, a coating is sprayed onto the workpiece by way of at least one painting device, and in an extraction station, which is arranged outside the painting station, air with overspray is extracted out of the painting station via an extraction device with a filter element, wherein overspray is separated out of the extracted air at the filter element. According to the invention it is provided that the exhaust air is led away via an extraction opening which is arranged in a lower region of the extraction station, wherein the filter element is placed onto the extraction opening, wherein the filter element is arranged approximately centrally in an extraction chamber of the extraction station. The invention further relates to a filter element provided for this purpose.

Abstract: A test system for examining a hollow body, in particular a cylinder bore in an engine block, comprises a measuring apparatus comprising an elongate body and a plurality of sensors which are connected to the body and are set up to carry out a distance measurement. The test system also comprises electronic control means which are set up to move the measuring apparatus into a hollow body to be examined and to determine an internal diameter of the hollow body on the basis of distance measurement data from the sensors. In order to examine hollow bodies of different diameters, at least some of the sensors are in the form of movable sensors which can be moved relative to the elongate body of the measuring apparatus. The electronic control means are also set up to select a measuring position of the movable sensors relative to the elongate body on the basis of a hollow body to be examined.

Abstract: The invention relates to an installation and a method for the metallic coating of a workpiece using a coating device, said coating device comprising a displaceable coating lance, by which a metal plasma jet can be generated to create a coating of metal particles. According to the invention, it is provided that the coating device with the coating lance and a measuring device for measuring the coating thickness are jointly integrated in the installation, and that the coating device with the coating lance as well as the measuring device are enclosed by a housing.

Abstract: The invention relates to a device and a method for the metallic coating of a work piece with a mobile coating lance (20), by means of which a metal plasma jet can be generated to create the coating consisting of metal particles. According to the invention, an extraction hood (30) is provided, which at least encloses an axial section of the coating lance (20) in a ring-shaped manner, and the extraction hood (30) has a ring-shaped holding unit (50), which is configured to take up the metal particles.
