  • Method for cleaning a finished and polished surface of a metal automotive wheel
    Patent number: 6676762
    Abstract: A method using irradiation of substrates (12) with ultra violet light to remove a surface contaminant is described. The light can be pulsed or continuous. The treated surfaces are more paintable and bondable.
    Type: Grant
    Filed: January 15, 2001
    Date of Patent: January 13, 2004
    Assignee: Board of Trustees of Michigan State University
    Inventors: Lawrence T. Drzal, Richard L. Schalek
  • Method for treatment of surfaces with ultraviolet light
    Patent number: 6565927
    Abstract: A method using irradiation with optical light having a wavelength of 160 to 500 nanometers without higher wavelengths with cooling of the surface during the irradiation to modify the surface (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light is filtered or the lamp (24, 106, 212, 306, 510) is restricted to the limited range to avoid the affects of the higher spectra. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water (14, 124, 204, 306, 410, 508) on the surface, preferably also in the presence of ozone in the water. The treated surfaces are more paintable and bondable.
