Resumo
Plates (8.1-mm-thick) from aluminum alloy AA2219-T87 are studied after friction stir welding. The plates are subjected to salt fog corrosion tests according to ASTM B117 at different pH values and different spraying times. The regions affected by corrosion are studied in different zones of welded joints by the methods of optical and transmission electron microscopy. The corrosion resistance is determined in acid, basic and neutral solutions. The resistances of the base metal and of the zones of welded joints are compared.
