  • the spray burner is fed via a feed device, a wire whose particles are injected in a gas stream to the inner surface of the cylinder.
  • the object of the invention is to provide a thermal spraying method and a device for coating the inner surface of a cylinder of an internal combustion engine or piston machine, which allows a simpler verification of the result of the coating process.
  • the thermal spraying method for coating the inner surface of a cylinder of an internal combustion engine or piston engine comprises the following method steps:
  • a thermal spray coating is applied to the inner surface of the cylinder. This can be done, for example, using the PTWA / RSW method known from the prior art.
  • An optical sensor device is inserted in the coated cylinder.
  • the optical sensor device is inserted into the inner volume of the cylinder so that it is in the axial direction between the base surfaces of the cylinder.
  • a scanning of the coated inner surface of the cylinder by the optical sensor device for detecting Aufoirefen in the coating For example, jarring may occur during the coating process because the wire supplied to the spray gun is not evenly melted.
  • these pimples can be detected automatically, so that a control of the quality of the coating process by a human accounts can. The faulty component can then be reworked if necessary.
  • the optical sensor device is a camera.
  • the optical sensor device is a laser interferometer, or a white light interferometer.
  • a holographic-based device may be used for the optical sensor device.
  • the distance from the axis of the sensor to the coated surface is preferably measured.
  • the optical sensor device may be arranged, for example, on the central axis of the cylinder, so that it should ideally have a constant distance from the entire coated inner surface of the cylinder.
  • a drop or a depression in the coating is assumed.
  • a threshold value can be defined, for example, by producing specially made faulty cylinders whose error lies exactly at the still permissible limit. By measuring this faulty sample part, it is possible to define an error threshold.
  • Various parameters of the compensation circle / cylinder can be considered, e.g. the mean.
  • the optical sensor device detects the position, number and size of the slugs in the coating and evaluates them by software algorithms to judge the quality of the coating process. For example, you can mathematical methods such as the Gauss equation to analyze the scattering on the surface of the cylinder. If the light scattering is above a defined threshold, the coated part is assumed to be defective. For example, the following parameters can be considered: standard deviations, variance, range or distribution. The size of the allowable deviation depends on how many drops or pits a particular application still allows.
  • the invention further relates to a thermal spray burner for applying a thermal spray coating on the inner surface of a cylinder of an internal combustion engine or piston engine.

  • the optical sensor device is configured to scan the coated inner surface of the cylinder and to detect pits or pits in the coating.
  • the distance from the central axis of the cylinder to its coated inner surface can be determined by the optical sensor device.
  • the optical sensor device is mounted on the central axis of the cylinder and is preferably rotatable about this.
  • FIG. 1 shows a cylinder 10 onto which, for example, by means of a PTWA method, a thermal spray coating 24 has been applied to its inner surface 26.
  • the thermal spray layer has a Auf scheme 14, which is caused by a mistake in the coating process on.
  • the distance a from the central axis M of the cylinder 10 to the coated inner surface 24 of the cylinder 10 thus has a lower value at the location of the Aufsches 14 than at the remaining inner surface of the cylinder.
  • This deviation is detected by an optical sensor device 12 introduced into the cylinder 10, for example a laser interferometer.
  • the coating can thus be recognized as defective and reworked if necessary.
