PROCEDIMENTO PER PRODURRE STRATI ASSORBITORI SOLARI PER ELEVATE TEMPERATURE

Process for producing heat-resistant solar absorber layers by electrodepositing a noble metal and a base metal with strong oxygen affinity, such as Cr, Co, Ni, in finely divided form, in which the base metal is then converted into the oxide by oxidation in a steam or oxygen atmosphere at low oxygen...

Zusammenfassung:Process for producing heat-resistant solar absorber layers by electrodepositing a noble metal and a base metal with strong oxygen affinity, such as Cr, Co, Ni, in finely divided form, in which the base metal is then converted into the oxide by oxidation in a steam or oxygen atmosphere at low oxygen potential. The deposition is carried out with pulsed direct current, the pulse time being very short.
