Laboratory-unit investigations of palladium-treated titanium foil for dry scrubber application

Titanium foil is employed for electron transparent windows in the electron beam dry scrubber process. The foil suffers corrosion, which limits the window life. Here, the examination of a palladium-coated window, prepared by ion beam assisted deposition and plasma source ion assisted deposition (PSIA...

Description
Summary:Titanium foil is employed for electron transparent windows in the electron beam dry scrubber process. The foil suffers corrosion, which limits the window life. Here, the examination of a palladium-coated window, prepared by ion beam assisted deposition and plasma source ion assisted deposition (PSIAD), after service in a pilot-scale plant is reported. Most significantly, the adhesion of the coating was reduced by the flue gas. Where the coating remained adherent, corrosion was negligible. Elsewhere, general, intergranular and pitting corrosion occurred. A PSIAD coating provided the best performance.
