processes to apply a galvanic corrosion barrier coating. Current processes are often hazardous and
environmentally unsafe as they involve chemicals such as hexavalent chromium. The handling and
disposal of the waste products of these wet chemical processes puts a significant financial burden on the
Department of Defense. This work aims to design and develop a process which employs an atmospheric
pressure plasma jet to substitute the wet chemical processes. The proposed project focuses on
depositing zirconia-silica conversion coatings on aluminum surfaces as a corrosion barrier. The process
utilizes existing chemical vapor deposition precursors with a much smaller chemical foot print. The
process is capable of depositing 100 – 300 nm zirconia-silica layers with relatively low carbon content
as observed under XPS. Initial tactical testing showed reduced water intrusion for painted silica coated
substrates.
