Abstract: (Al-Li) alloys contain certain alloying elements exhibit high elastic modulus, high strength and low density. These properties are main requirements in aerospace industries. These alloys are subjected to corrosion and corrosion/erosion during the application. The corrosion behavior was investigation on a function of alloying elements and corrosion medium. Tafel technique was adopted to record the corrosion current. Corrosion/erosion were determined by suitable equipment. Results obtained showed that tests conducted in tap water showed that corrosion current of Al-Li-Cu was 7% of the corresponding value of the reference alloy (Al-Li). In H2SO4, however, it was 14% with respect to the base alloy. For (Al-Li-Cu-Mg) alloy the corrosion current in tap water was only 2.5% with respect to the base alloy (Al-Li). In H2SO4 the corrosion current was 67% with respect to the base alloy. In corrosion/erosion test, the weight (loss/area) the base metal (Al-Li) was 4.4*10-6 g/mm2. For (Al-Li-Cu) alloy it was only 0.95*10-6 g/mm2 while (Al-Li-Cu-Mg) alloy gives 1.95*10-6 g/mm2.
