Legacy Coating Stripping (Milestone 2). Improved Magnesium Protection for DoD Aviation and Weapon Component Technology

Abstract

This report details the testing, performance requirements and test results used to meet Objective 2 of the Joint Test Protocol. There are three (3) anodized coating applied to new build magnesium aerospace castings. Objective 2: Design and validate the stripping process needed to remove old coatings from legacy components. Feedback from engineers at CCAD and TAG has indicated that the successful application of an Immersion Tagnite coating on legacy components is primarily driven by the condition of the parts upon entering the Tagnite process. Experience has shown that all residual paints and coatings must be removed prior to introduction into the Tagnite process in order to apply a high quality Tagnite coating. In addition, several of the legacy parts were made from AZ91C or AZ91E. These alloys have a lot of porosity which can lead to fluid see page after Tagnite application, resulting in a compromised coating.
