Abstract AR
تم حساب معامل الاحتكاك عمليا لسبائك الألمنيوم - سليكون من خلال ربط مقياس الانفعال بجهاز البلى الالتصاقي لغرض تسجيل قراءات الانفعال المايكروية.
أجريت المجانسة الحرارية لسبائك الألمنيوم - سليكون المصبوبة و المحورة لفترات زمنية طويلة (1 - 40 ساعة) لغرض دراسة تأثيرها على الاحتكاك.
استخدم المجهر الإلكتروني الماسح بنجاح لغرض دراسة تضرر المنطقة السطحية أثناء الانزلاق.
أوضحت النتائج زيادة معامل الاحتكاك بزيادة ضغط التحميل لجميع السبائك المصبوبة و المحورة و المجانسة.
أدت المجانسة الحرارية إلى تغيرات واضحة في السلوك الاحتكاكي لسبائك الألمنيوم - سليكون المصبوبة و المحورة.
أسهمت العديد من الآليات في تضرر سطح سبائك الألمنيوم - سليكون أثناء الانزلاق.
Abstract EN
The coefficient of friction was experimentally calculated for aluminum-silicon alloys by connecting a strain gauge to the arm of pin-on-disc wear machine in order to take microstrain readings from the strain-meter.
As-cast and modified aluminum-silicon alloys were thermally homogenized for long periods of time (1-40hr) in order to study the effect of homogenization on friction.
Scanning electron microscopy was successfully used to build up the mechanism of surface damage during sliding.
The results showed that the coefficient of friction was increased with increasing bearing pressure for as-cast, modified and homogenized aluminum-silicon alloys.
Thermal homogenization led clearly to remarkable changes in the frictional behavior of as-cast and modified aluminum-silicon alloys.
Many mechanisms were responsible for aluminum-silicon alloys surface damage during sliding.
