Remove And Treat Aircraft Corrosion Flashcards
What must be done to a piece of aluminum alloy to remove surface corrosion and to treat the metal to prevent further corrosion?
Remove the corrosion residue with a bristle brush or a nylon scrubber. Neutralize the surface with chromic acid or with some type of conversion coating. Protect the surface from further corrosion with a coat of paint.
What is used to keep corrosion from forming on structural aluminum alloy?
An oxide coating or aluminum cladding.
How may rust be removed from a highly stressed metal part?
By glass bead blasting, by careful polishing with mild abrasive paper, or by using fine buffing compound on a cloth buffing wheel.
How should an A&P minimize corrosion at piano hinges?
They should be kept as clean and dry as practicable and lubricated with a low viscosity moisture dispensing agent.
What tools are proper for removing corrosion from aluminum alloy?
Aluminum wool or aluminum wire brushes. Severe corrosion can be removed with a rotary file.
What can be used to repair the anodized surface of an aluminum alloy part?
A chemical conversion coating such as Alodine.
What type of device is used to remove surface corrosion from a piece of magnesium alloy?
A still hog-bristle brush.
How is the inside of structural tubing protected from corrosion?
The tubing is filled with hot linseed oil and then drained.
