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.

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.

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. A calibration station is provided and the electronic control means are set up to carry out a calibration process for the movable sensors. A corresponding method is also disclosed.
