Testing of Zirconium-Based Pretreatments at NASA Kennedy Space Centers Beachside Atmospheric Corrosion Test Site

Abstract

The objective of this work was to optimize zirconium-based pretreatment applications in a lab setting and test samples using a galvanic panel with stainless steel fasteners. The zirconium-based pretreatments were applied at the same time using the same cleaning and deoxidizing methods as currently approved hexavalent and trivalent chromium conversion coatings. The panels were then primed with chrome-free aviation primer and chemical-agent-resistant topcoat. The galvanic panels were exposed for 1 year at Kennedy Space Centers Beachside Atmospheric Corrosion Test Site in Florida and monitored for corrosion on a monthly basis. This effort identifies performance of possible hexavalent chromium conversion coating alternatives in an aggressive outdoor environment.
