AMINO ALCOHOL TREATMENT FOR SOL-GEL CONVERSION COATINGS, SUBSTRATES INCLUDING THE SAME, AND METHODS OF MAKING THE SUBSTRATES

摘要

An article includes a substrate, a sol-gel conversion coating on at least a portion of the substrate, and a treatment layer on at least a portion of the sol-gel conversion coating. The treatment layer includes an amino alcohol. A method of manufacturing the article includes applying a partially cured sol-gel composition to at least a portion of a substrate, at least partially drying the partially cured sol-gel composition to form the sol-gel conversion coating, applying a solution including an amino alcohol to at least a portion of the sol-gel conversion coating, and at least partially drying the solution including the amino alcohol.
