Embodiment Construction
[0047] figure 1 A measuring device 10 of one embodiment of the coating system according to the invention is shown schematically. The measuring device 10 has been moved into the cavity 1 which may in particular be the cylinder bore 1 of the engine block.
[0048] The side walls 2 of the cavity are to be coated, whereby desired wall properties can be obtained, for example to increase the efficiency of the engine.
[0049] The side walls 2 are formed by the side surfaces of the cavity 1, here also referred to simply as "wall 2".

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 coating lance, the thickness of said coating of variable thickness being dependent on the determined diameter values. The invention additionally describes a corresponding coating system.
Description
technical field [0001] In a first aspect, the invention relates to a method for coating a cavity wall, in particular a cylinder bore of an engine block, according to the preamble of claim 1 . [0002] In a second aspect, the invention relates to a coating system for coating a cavity wall, in particular a cylinder bore of an engine block, according to the preamble of claim 11 . Background technique [0003] Engine blocks of this type are used, for example, in internal combustion engines of motor vehicles. It consists of a number of cylinder bores whose dimensions and wall characteristics meet precise requirements to ensure that the combustion engine is as efficient as possible. In this case, a cylinder bore can generally be understood as a cylindrical cavity with an arcuate, especially circular cross-section. A coating is provided on the inner wall of the cylinder bore, which coating needs to comply with the requirements for its layer thickness with the highest possible pre...
