Textured black brass spectrally selective coating
A textured black brass selective coating has been reported in this paper. These textured black brass selective coatings have been obtained by using chemical conversion process. They exhibit initial solar absorptance (alpha) similar to 0.96 and thermal emittance epsilon(100) similar to 0.17 and are reproducible. These have been annealed up to 250 degrees C in air and at 150 degrees C in vacuum (10(-3) Torr) possessing solar absorptance (alpha) similar to 0.90. TEM, XRD and FTIR analyses have also been reported which suggests that the coating consists of multi-phases.
