Problems solved by technology

[0011] A disadvantage of the known coating systems is that, in many cases, the actual dimensions of the cavities coated have an undesirably high deviation from the target value, which deviations can at best be determined in tests, but not be avoided

Embodiment Construction

[0051] 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.

[0052] 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.

[0053] The side walls 2 are formed by the side surfaces of the cavity 1, here also referred to simply as "wall 2".

Abstract

The invention relates to a method for coating the walls of a cavity, in particular the cylinder bore of an engine block. In this method, a coating is applied to the cavity walls with a coating gun. In addition, a measuring device is used to measure the cavity diameter. According to the invention, the method is characterized in that at least a plurality of diameter values ​​of the first cavity are measured at different heights of the first cavity with a measuring device, and that the wall of the first cavity or the second cavity is measured with a coating spray gun. A variable-thickness coating is provided, the thickness of which depends on the determined diameter value. In addition, the present invention also 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. [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. 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 precision. [0004] The properties of such coated cavities can be checked by conv...
