AN EXPERIMENTAL STUDY TO DEVELOP ALUMINUM CORROSION RESISTANCE IN ACIDIC SOLUTION BY DIFFERENT RATIOS OF ADDITIVE ELEMENTS

Abstract

In this work the corrosion behavior of aluminum alloy includes copper with different ratio is investigated by immersing the specimens in acidic solution (HCL& H_(2 ) 〖SO〗_4) with concentration (5%,10%) then put in furnace at three temperature degree(40,60.80)C^0 and holding for (30)minutes the results showed that increased in (Cu) at alloy contain leads to increase in weight losses while when fixed cupper ratio and increased (Ni) at alloy contain the weight losses decrease .corrosion rate of studied alloy increase in(HCL) solution more than(H_(2 ) 〖SO〗_4) .
