رئيس الفريق 4 : بومعزة عبد الشريف الفريق 04 إن عملنا البحثي في AAFPA مخصص لأكسدة السبائك الفائقة (FeCrAlY). وهذه المواد الخاصة الموجودة في تكنولوجيا الطيران والفضاء قادرة على مقاومة درجات الحرارة العالية (بين 900 و1200 درجة مئوية). وترتبط هذه المقاومة للبيئة العدوانية بتكوين طبقة واقية فعالة جداً كيميائياً وحرارياً؛ هذه الطبقة وهي ألفا الألومينا. ومع ذلك، في ظل ظروف معينة، ليست هذه الطبقة هي الوحيدة التي تتشكل، ولكن هناك أيضًا طبقات من الأكاسيد مثل أكاسيد (Fe-Cr) ولكن أيضًا ألومينا انتقالية. إن عملنا البحثي مخصص لحركية تكوين هذه الطبقات. ومن أجل فهم ظاهرة تكون هذه الأكاسيد؛ وينبغي النظر في طريقتين للمضي قدما: – أكسدة السبائك المكونة للألمنيوم (FeCrAlY..) بين 600 درجة مئوية و 1200 درجة مئوية،  –   تكليس سلائف الألومينا (مثل الجيبسايت والبوهميت) بين 600 درجة مئوية و1200 درجة مئوية، مع أخذ ذلك في الاعتبار، وهو أمر في غاية الأهمية ومشجع ويسمح بتحليل جيد للنظام....اقرأ أكثر
