چکیده
The polarization technique has applied to investigate the factors affecting aluminium alloy1050A corrosion used in cooling towers. In addition, the storage conditions were optimized using the statistical method central composite design (CCD). The primary goal of this study was to identify factors influencing corrosion of aluminium alloys used in dry heat transfer towers in Yazd combined cycle power plants, which was the result of experimental design. The cross-sections studied were performed using SEM imaging and EDS analysis. The results showed thatthree factors including pH, temperature, and the amount of available iron ions (ш) in environment, are effective on alloy corrosion during towers operation (Heller Type). In conclusion, increase of pH, water temperature, and the amount of iron ions (ш) in the environment, have led to increase in the corrosion of applied aluminium alloys in heler towers of the combined cycle plants .The results show that corrosion was the pH of the solution exponentially effective. In addition to maintaining optimum conditions mentioned alloy to minimize corrosion rates in this study wereextracted.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
