摘要： A method for roughening a cylinder bore wall to be coated of a component, at least one groove, running around the central longitudinal axis, and at least one associated groove web, are generated such that the at least one groove web, in a radial direction directed toward the central longitudinal axis, forms first undercuts for a coating which is to be applied. Axial grooves running in the cylinder bore wall transversely to the at least one groove are generated such that the at least one groove web, in a peripheral direction about the central longitudinal axis, forms respective second undercuts for the coating which is to be applied. An adhesion of the coating which is to be applied, in the peripheral direction, is improved, so that stress cracks or detachments owing to a different thermal expansion of the component and of the coating which is to be applied are avoided.

摘要： 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.

摘要： 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.

摘要： A sensor device for the inspection of the surface of a cylindrical hollow enclosure having at least one sensor unit set up for an optical confocal distance measurement. The at least one sensor unit has an elongated shape and exhibits an external optical system, through which a measurement device in which light can be emitted and received, is disposed transversely to a longitudinal axis of this sensor unit. The sensor device additionally comprises a movement mechanism, which is adapted to move the at least one sensor unit in one direction of motion into and out of a cylindrical hollow enclosure to be inspected. Control means are provided for measuring raisings of a surface of the cylindrical hollow enclosure and are adapted to control the at least one sensor unit for carrying out a first distance measurement, during which the measuring direction relative to the direction of motion is at an angle from 20° to 85°, and to control the at least one sensor unit for carrying out a second distance measurement, during which the measuring direction relative to the direction of motion is at an angle from 95° to 160°. To this end, the measuring direction of the at least one sensor unit can be at an angle between 95° and 175° relative to the longitudinal axis of said sensor unit, wherein this sensor unit is mounted on a rotatable bearing such that one and the same sensor unit can be moved to different positions of rotation for the first distance measurement and for the second distance measurement. Alternatively, the at least one sensor unit can comprise at least one first sensor unit and at least one second sensor unit, the first sensor unit being formed and linked with the movement device in such a manner that its measuring direction relative to the direction of motion is at an angle from 20° to 85°, and the second sensor unit being formed and linked with the movement device in such a manner that its measuring direction relative to the direction of motion is at an angle from 95° to 160°. In addition, a corresponding method is disclosed.
