  • Process for applying thin molybdenum containing coatings on aluminum for solar energy absorption
    Patent number: 4104136
    Abstract: A thin, adherent coating is described that is highly absorptive to solar energy and has a low emissivity for thermal energy, thereby being a useful selective surface for solar energy collection. This coating is formed on aluminum and its alloys by a simple electrochemical process and consists of complex aluminum and molybdenum oxides and metallic molybdenum which are deposited as a near-monatomic layer of molybdenum and its oxides. The coating withstands exposure to 400.degree. F (204.degree. C) and 1 hour in boiling water without change in properties.
    Type: Grant
    Filed: June 3, 1977
    Date of Patent: August 1, 1978
    Assignee: Reynolds Metals Company
    Inventors: Daniel Joseph Schardein, Ruth Diane Lloyd
