Abstract (en)

[origin: CN117295192A] The invention relates to a method for producing a heating device having a carrier and at least one heating conductor applied thereto, comprising the following steps: providing a carrier having a heating conductor side, on which an anodized layer is produced, wherein the anodized layer is applied directly to the carrier/heating conductor side thereof, and the at least one heating conductor is applied over the anodized layer in a thick film process. Advantageously, the anodized layer may be fabricated as a hard anodized layer. Additional insulating and/or thickening layers may also be applied to the anodized layer.
