Abstract: The system for coating a surface of an article (3) such as cooking device exposed in use of temperature intervals of 100[deg] C, where a basic material (92) of an article part having the surface to be coated has thermal expansion coefficients, which differ around 1-10% of a coating material to be applied, comprises a first device for mechanically processing the basic material or the applied coating material, and a second device for applying the coating material, where the second device or one of the two devices has a treatment unit, with which a dilation balancing area (91, 93) is producible. The system for coating a surface of an article (3) such as cooking device exposed in use of temperature intervals of 100[deg] C, where a basic material (92) of an article part having the surface to be coated has thermal expansion coefficients, which differ around 1-10% of a coating material to be applied, comprises a first device for mechanically processing the basic material or the applied coating material, and a second device for applying the coating material, where the second device or one of the two devices has a treatment unit, with which a dilation balancing area (91, 93) is producible over a basic material surface. The first device has a first positioning device for a first of the treatment unit for processing the article surface and the second device has a second positioning device for a second of the treatment unit for applying the coating film. The system has a linearly acting conveying device, with which the article is bringable at a conveying path from the device to device for coating or processing i.e. treatment. Each positioning device has a displacement device, with which a corresponding treatment unit is vertically displaced to a moving direction of the conveying device where a meander treatment is performed. Each device has a holding device formed as vacuum holder, with which each article is holdable for treatment. The conveying device has a conveying unit and a lifting unit acting on the conveying unit, where the respective article is removed from the holding device with the lifting unit and is transportable from one of the devices to the other. The second device or one of the two devices has an adjustable height-adjustment device, so that the dilation balancing area is producible. Each holding device is rotatably formed around a central axis where a linearly rotational-symmetrical treatment of the respective article is performed under the aid of the conveying device. One of the devices is formed as a band with a suction device and the devices are arranged to each other. A first device has a sand blasting device, a grinding device or a steel work beam device. The second device has a first thermal spraying device for an adhesive layer, a second thermal spraying device for a first induction layer or a third thermal spraying device for a second induction layer. The conveying device is formed by all devices, so that a bottom of each article formed as cooking device is treated in which the article is transportable with the conveying device to the sand blasting device from the first thermal spraying device to second and then third thermal spraying device to produce the cooking device as cooking device with an induction coating. Independent claims are included for: (1) a method for coating a surface of an article such as cooking device; and (2) an article.
