Abstract AR
إن السبب الرئيس في استخدام المرشحات المصنعة من مساحيق المعادن هو قابلية الحصول على نسبة مسامية مسيطر عليها.
الدراسة أنجزت باستخدام سبيكة برونز على شكل مسحوق.
تم تحضير النماذج بطريقتين : (1) كبس على البارد عند ضغوط كبس مختلفة و حجم حبيبات المسحوق مختلفة (Cu - 7.5 % Sn - 0.1 % Fe - 0.3 % Pb - 0.15 % Zn) كذلك زمن و حرارة التلبيد مختلفين، (2) الطريقة الأخرى لتحضير العينات هي Loose Powder Sintering.
المكبوسات لبدت في جو مسيطر عليه.
بعد تحضير السطح، العينات عولجت لحساب المسامية الظاهرية.
لقد وجد أن الطريقة الأفضل لإنتاج المواد ذات المسامية العالية حوالي (59 %) هي (Loose Powder Sintering) عند استدام الظروف الملائمة.
المسامية التي تم الحصول عليها باستخدام كبس على البارد و التلبيد تتراوح بين (5 – 41 %) و الكثافة تتراوح بين (58.6 – 94.3 %) من الكثافة النظرية للمادة الخام.
Abstract EN
The ability to achieve close control of porosity and pore size is the main reason that filters are produced by powder metallurgy.
This study was performed using bronze alloy powder (Cu-7.5 %Sn-0.1 %Fe-0.3 %Pb-0.15 %Zn).
The samples were prepared by two methods : (1) cold die compacting at different particle size, compacting pressure, sintering time, and sintering temperature, and (2) loose powder sintering.
The compacts were sintered under controlled atmosphere.
After surface preparation of the samples, the microstructure was used to compute the apparent porosity.
It was found that the (Loose Powder Sintering) method is optimum method to produce highly porous materials with ( 59 %) porosity when selecting the proper conditions.
The porosities obtained using cold die compaction are ranging between (5-41 %) and sintered density ranging between (58.6-94.3 %) of the theoretical mean density of the starting materials.
