Abstract AR

تم استخدام السبيكة (Ti-5Al-2.5Fe) المعاملة حراريا (المحلول الصلب) و المدرفلة في طور (a+b) و بدرجة 970 °م و بثلاث أوساط للتبريد هي (الماء, الهواء و داخل الفرن) ثم أجريت عملية التعتيق لمدة أربع ساعات للنماذج التي بردت بالماء و الهواء و بدرجة 550 °م.

تم غمر خمسة نماذج من كل معاملة حرارية تم غمرها في مشبهات محاليل الجسم لمدة 3 أشهر.

الدراسة أوضحت تأثير نوع التبريد للمعاملة الحرارية على سلوك التآكل للنماذج المغمورة في محلول بلازما الدم.

أظهرت فحوصات EDXRF ترسب الكالسيوم و الفوسفور على السبيكة مكونا طبقة شبيهة بالعظم مما يساعد في زيادة ملائمتها البايولوجية للاستخدامات الطبية.

Abstract EN

Heat treatment by solid solution method in the α+β phase region was used at 970°C for Ti-5Al-2.5Fe alloy.

The specimens cooled under different cooling media [water quenched (WQ), air cooled (AC) and furnace cooled (FC)], and subsequently aged at 550°C for 4 hours.

Five specimens from each treatment were immersed in simulated body fluid SBF for a period of time (3 months).

The dependence of corrosion rate on compositional variation in the phases resulted from various type of cooling rates are discussed based on immersion tests.

The EDXA results show the precipitation of phosphate and calcium compounds on the alloy after 3 months of immersion in blood plasma solution forming a bone-like apatite, which enhanced the alloy biocompatibility making it more suitable to use as biomedical implant
