Abstract

ALDC 12 Al alloy is often corroded with some forms such as pitting corrosion, intergranular corrosion, and galvanic corrosion etc., in case of severe corrosion environment like seawater Annealing heat treatment was performed to improve the corrosion resistance of ALDC 12. Hardness was decreased with increasing of annealing temperature, however its corrosion resistance was clearly improved with increasing of annealing temperature.
