Abstract
Results are given of laboratory experiments and periodic examinations on board ship to determine the service behavior of aluminum alloys in wooden hull minesweepers constructed with aluminum alloy frames.
Service failures are illustrated. Most of them were caused by use of incorrect materials, substitution of materials not given in specifications, poor industrial manufacturing or insufficient technical control.
Service behavior of stainless steel used in conjunction with aluminum was good if the surface area ratio of the two materials was about 1 to 5. Zinc chromate as a corrosion inhibitor for aluminum alloys gave satisfactory service.
Other topics included are lagging with asbestos, aluminum corrosion products and use of greases and lubricants containing graphite. 6.4.2
