Abstract AR
لقد تم دراسة تأثير تيارات مسلطة على الفولاذ الكاربوني في محلول تركيز الملح فيه 0.1 مولاري و تحت ظروف جريان (0-0.262 م/ثا) و درجات حرارة (35-55 م ْ) باستخدام قطب الاسطوانة الدوارة.
سلطت قيم مختلفة لتيارات الحماية لحماية الفولاذ الكربوني من التآكل, تم تسليط تيار التآكل, ضعف تيار التآكل و 4, 2 من تيار التآكل تحت سرعات و درجات حرارة مختلفة, تم ملاحظة تغير فولتية الحماية مع الوقت و مع السرعات في مختلف التيارات المسلطة.
وجد أن معدل التآكل للفولاذ الكربوني يزداد مع السرعات و يكون تغيره مع درجات الحرارة غير ثابت و أن تيارات الحماية المطلوبة تختلف مع درجات الحرارة و تزداد عند زيادة سرعة الدوران، و فولتية الحماية تقل (تصبح أكثر سالبية) مع زيادة الوقت و مع زيادة درجات الحرارة.
Abstract EN
The effect of applied current on protection of carbon steel in 0.1N Na Cl solution (pH = 7) was investigated under flow conditions (0-0.262 m / s) for a range of temperatures (35-55°C) using rotating cylinder electrode.
Various values of currents were applied to protect steel from corrosion, these were Iapp.
Icorr.
Iapp.
= 2Icorr.
And Iapp.=2.4Icorr.
Under stationary and flow conditions.
Corrosion current was measured by weight loss method.
The variation of protection potential with time and rotation velocity at various applied currents was assessed.
It is found that the corrosion rate of carbon steel increases with rotation velocity and has unstable trend with temperature.
The protection current required varies with temperature and it increases considerably when the rotation velocity was increased.
The protection potential decreases appreciably (shifts to more negative) with time and with increasing rotation velocity.
Also it shifts to more positive with increasing temperature.
