摘要:
The radiation selective absorber coating of the invention includes two or more barrier layers arranged over each other on a substrate surface, an infrared-range reflective layer arranged on the two or more barrier layers, and at least an absorption layer arranged over the infrared-range reflective layer and a final antireflection layer arranged over the absorption layer. The absorber pipe, especially for a parabolic trough collector, is a steel pipe, on whose outer side the radiation selective absorber coating is applied. In the method of making the absorber pipe a first oxide barrier layer is provided on the outer side of the steel pipe by thermal oxidation, and then a second barrier layer, an infrared-range reflective layer, an absorption layer and a final antireflection layer are applied by gas-phase physical deposition.
