  • Chapter 8: Cleaning & Corrosion Control › Corrosion Removal › Surface Cleaning and Paint Removal

    There are other methods for paint removal that have minimal impact upon the aircraft structure, and are considered “environmentally friendly.” Wherever practicable, chemical paint removal from any large area is to be accomplished outside (in open air) and preferably ... shaded areas. If inside removal is necessary, adequate ventilation must be assured. Synthetic rubber surfaces, including aircraft tires, fabric, and acrylics, must be thoroughly protected against possible contact with paint remover. Care must be exercised in using paint remover, especially…

  • Chapter 8: Cleaning & Corrosion Control › Corrosion of Aluminum & Aluminum Alloys › Treatment of Unpainted Aluminum Surfaces

    surface is particularly difficult to clean, a cleaner and brightener compound for aluminum can be used before polishing to shorten the time and lessen the effort necessary to get a clean surface. 3. Treat any superficial corrosion present using ... corroded area for 5 to 20 minutes, and then remove the excess by rinsing and wiping the surface dry with a clean cloth. 4. Overcoat the polished surfaces with waterproof wax. Aluminum surfaces that are to be subsequently painted…

  • Chapter 8: Cleaning & Corrosion Control › Processes & Materials Used in Corrosion Control › Surface Preparation

    Processes & Materials Used in Corrosion Control Metal Finishing Aircraft parts are almost always given some type of surface finish by the manufacturer. The main purpose is to provide corrosion resistance; however, surface finishes may also be applied to increase wear ... resistance or to provide a suitable base for paint. In most instances, the original finishes described in the following paragraphs cannot be restored in the field due to unavailable equipment or other limitations. However, an understanding of the various types…
