AC 43.13-1B 9/8/98 brass, copper, or steel. This treatment cannot be used with parts containing aluminum inserts or fasteners because the high alkalinity of the bath attacks the aluminum. 6-36. GALVANIC ANODIZING TREAT- MENT. An electrolytic process that provides a paint base and corrosion-preventive film on magnesium alloys containing manganese. 6-37. CLADDING. Aluminum alloys which are susceptible to corrosion are frequently clad with pure aluminum. Slight pits, scratches, or other defects through the cladding material must be avoided, since the aluminum alloy core will corrode rapidly. 6-38. METAL SPRAYING. Metal is melted and sprayed on the surface to be protected. The surface must be properly prepared and thoroughly cleaned to prevent peeling of the sprayed coat. 6-39. SHOT-PEENING. Shot-peening and other treatments, by which the surface can be placed in compression, are effective in pre venting stress corrosion. 6-40. ORGANIC COATINGS. Zinc chro mate primer, enamels, chlorinated rubber com pounds, etc., are organic coatings commonly used to protect metals. 6-41. DOPE PROOFING. When doped fabrics are applied over an organic finished metal structure, the dope will have a tendency to loosen the finish on the metal. For this rea son, organic coatings on the metal are usually covered with a dope-proof paint, with metal foil, or with cellulose tape to prevent the dope from soaking through. 6-42. TUBE INTERIORS. Protect the inte riors of structural steel and aluminum tubing against corrosion. A small amount of water entrapped in a tube can corrode entirely through the tube thickness in a short period. Coat the tube interior by flushing with hot lin seed oil, paralketone, or other approved corro sion inhibitor. The flushing liquid is usually introduced through small holes drilled in the tubing. Allow the flushing liquid to drain and plug the holes with a screw or by other means to prevent entry of moisture. Air and water tight sealing of the tubing will also give ade quate protection against corrosion if the tubing is internally dry before being sealed. 6-43.6-49.
