Process for applying a metal-organic framework-containing corrosion resistant coating to a substrate
Patent number: 11261336Abstract: Processes, compositions and agents are included for inhibiting corrosion in various substrates, for example metal substrates. Corrosion inhibitors include organometallic polymers such as metal-organic frameworks (MOFs), including compositions and processes comprising MOFs for inhibiting corrosion in metal substrates. In some aspects, a method of protecting a substrate from corrosion includes applying a protective composition including a corrosion inhibitor to the surface of a substrate, where the corrosion inhibitor includes a metal organic framework (MOF).Type: GrantFiled: March 10, 2017Date of Patent: March 1, 2022Assignee: THE BOEING COMPANYInventors: James Ivan Mardel, Ivan Stewart Cole, Paul Andrew White, Anthony Ewart Hughes, Tracey Anne Markley, Timothy Graham Harvey, Joseph Osborne, Erik Sapper -

Patent number: 6503565Abstract: A metal surface which has been cleaned using an alkaline based solution is treated with an acidic solution which contains rear earth ions to remove any smut which may have been produced during the alkaline cleaning. A coating is formed on the cleaned surface using a different acidic solution containing rare earth cations which have multiple valence states. When the surface is reacted with coating solution, an increase in the pH at the metal surface indirectly results in precipitation of a rare earth metal such as cerium onto the surface. Alternatively, after the removal of the smut, the surface may be coated using a painting technique.Type: GrantFiled: September 29, 1997Date of Patent: January 7, 2003Assignee: Commonwealth Scientific and Industrial Research OrganisationInventors: Anthony Ewart Hughes, Karen Joy Hammon Nelson, Russell James Taylor, Bruce Roy William Hinton, Mark Julian Henderson, Lance Wilson, Sally Ann Nugent
