Abstract AR
لقد تمت دراسة تأثير ثلاث مشتقات من أملاح : (N,N'-diquaternized-4.4' dipyridinium) (TMdPyBr2,HMdPyBr2 and MPhdPyC12) و هي كمثبط للتآكل العام، و الثاقب في محلول 0.1M من حمض الهيدروكلوريك عند درجات حرارة مختلفة.
و أثبتت نتائج جهد التآكل و القياسات القطبية أن الثلاث مركبات من النوع المثبط الأنودي و الكاثودي و ذلك بالامتزاز على سطح الصلب و هو يتبع لونجمير ايزوثيرم.
و أن مشتقات أملاح تثبيط التآكل حسنت من خمول الحديد الصلب و أن كفاءة التثبيط زادت مع زيادة درجة الحرارة ما عدا (TMdPyBr2).
و أن ميكانيكية التثبيط نوقشت من وجهة نظر التركيب الجزئي لأملاح البريديليم.
Abstract EN
The inhibitive actions of three sensitized derivatives of N,N'-diquaternized 4,4'-dipyridinium salts (TMdPyBr2, HMdPyBr2 and MPhdPyCl2) on general and pitting corrosion of 430 stainless steel (SS) in aerated 0.1M HCl have been studied at different temperatures.
Corrosion potential and polarization measurements proved that the three compounds act as mixed type inhibitors with dominant anodic and their adsorption on the steel surface obey Langmuir adsorption isotherm.
The diquaternized salts inhibited the corrosion and improved the passivation of the SS, their inhibition efficiencies (except for TMdPyBr2) increased with temperature.
The mechanism of corrosion inhibition was discussed in the light of the molecular structure of the dipyridinium salts.
