چکیده
خوردگی حفره‌ای یکی از مخرب‌ترین انواع خوردگی موضعی در آلیاژهای غیرفعال هوافضایی مانند فولاد و آلومینیوم است و حضور یون‌های کلرید موجب تشدید آغاز و رشد این پدیده می‌شود. هدف این پژوهش، سنتز نانوکامپوزیت هیبریدی گرافن کاهش‌یافته و چارچوب فلزی-آلی پایدار و بررسی عملکرد آن در مهار خوردگی حفره‌ای فولاد هوافضایی از طریق ایجاد سازوکارهای سدکنندگی و بازدارندگی فعال است. نانوکامپوزیت هیبریدی گرافن کاهش‌یافته-چارچوب فلزی-آلی پایدار با ساختار هشت‌ضلعی از طریق رشد درجا بر صفحات گرافن کاهش‌یافته سنتز شد و با آزمون‌های طیف‌سنجی رامان، پراش اشعه ایکس و میکروسکوپ الکترونی روبشی مشخصه‌یابی گردید. سپس عملکرد مقاومت به خوردگی گرافن کاهش‌یافته، چارچوب فلزی-آلی و نانوکامپوزیت هیبریدی در محلول نمکی 3.5 درصد وزنی با استفاده از آزمون‌های الکتروشیمیایی امپدانس و اندازه‌گیری پلاریزاسیون بررسی شد. نتایج ریزساختاری نشان داد نانوذرات چارچوب فلزی-آلی با مورفولوژی چندوجهی یکنواخت بر سطح گرافن کاهش‌یافته رشد کرده و ساختار هیبریدی پایدار ایجاد کرده‌اند. آزمون‌های امپدانس نشان دادند نانوکامپوزیت هیبریدی بالاترین مقدار مقاومت کل را (4038 اهم.سانتیمتر مربع بعد از 35 ساعت غوطه‌وری) ارائه داد. افزون‌براین، نتایج اندازه‌گیری پلاریزاسیون کاهش چشمگیر چگالی جریان خوردگی و افزایش بازده حفاظت تا ۸۳ درصد را نشان داد. عملکرد برتر این سامانه به اثر هم‌افزای سد فیزیکی گرافن کاهش‌یافته و رهایش کنترل‌شده یون‌های روی و ۲-متیل‌ایمیدازول از چارچوب فلزی-آلی نسبت داده شد که موجب مهار هم‌زمان واکنش‌های آندی و کاتدی شده است.

چکیده English

Pitting corrosion is one of the most destructive forms of localized corrosion in aerospace passive alloys such as steel and aluminum, and the presence of chloride ions accelerates the initiation and growth of this phenomenon.. The aim of this study is to synthesize a hybrid nanocomposite of reduced graphene oxide and a stable metal–organic framework with an eight-membered structure and to evaluate its performance in inhibiting pitting corrosion of steel through barrier and active inhibition mechanisms. The hybrid nanocomposite of reduced graphene oxide and the stable metal–organic framework with an eight-membered structure was synthesized via in situ growth on reduced graphene oxide sheets and characterized by Raman spectroscopy, X-ray diffraction, and field emission scanning electron microscopy. The corrosion resistance performance of reduced graphene oxide, the metal–organic framework, and the hybrid nanocomposite was evaluated in 3.5wt.% saline solution using electrochemical impedance spectroscopy and polarization measurements. Microstructural results indicated that the metal–organic framework nanoparticles with uniform polyhedral morphology grew on the reduced graphene oxide surface, forming a stable hybrid structure.Impedance tests showed that the hybrid nanocomposite provided the highest total resistance, reaching 4038 ohm.cm² after 35 hours of immersion. Moreover, polarization measurements demonstrated a significant reduction in corrosion current density and an increase in protection efficiency up to 83%. The superior performance of this system was attributed to the synergistic effect of the physical barrier of reduced graphene oxide and the controlled release of zinc ions and 2-methylimidazole from the metal–organic framework, simultaneously inhibiting anodic and cathodic reactions.
