Notizen: Abstract The composition of a reactively sputtered graded stainless steel/carbon cermet with a copper base layer has been studied using Auger electron spectroscopy/argon ion depth profiling and X-ray photoelectron spectroscopy. The interlayer structure of newly deposited films is independent of the underlying substrate but exhibits strong substrate interactions following baking at 670K for 60 min. Similar behaviour is found in films aged in air at room temperature over a period of months. Metal oxide substrates are most reactive, causing oxidation within the film. This type of multilayer cermet is used in solar collectors as a spectrally selective film. The implications of these findings for the long term integrity and performance of the thermal solar collectors are discussed.
