Abstract

تم قياس وتحديد سلوك التآكل والاحتكاك لطبقة تبطين مركّبة من مادتي الكربون والفلور بنسب تركيب معيّنة لكلٍ منها .

تم رش طبقة التبطين هذه حرارياً على قرص مصنوع من حديد الصب ( فونت ) .

تم إجراء الانزلاق بين مسامير أسطوانية مصنوعة من مواد تبطين مكابح عضوية والأقراص المطلية ( المغلّفة ) وغير المطلية .

تم تحديد خواص مواد التبطين بعد قياس قيم القساوة والمسامية ومقاومة التآكل فيها .

تم اختبار خواص مقاومة التآكل في طبقة التبطين اعتماداً على عملية تعريضها لمادة Nacl  بنسبة صغيرة لمدة تزيد عن مائة وخمسين ساعة.

تميزّت طبقة التبطين بأفضل مقاومة تآكل ، تم إجراء اختبارات قياس قيم التآكل والاحتكاك عند قيم ضغط تماس متفاوتة مابين (1.5MPa ÷ 7MPa) وبسرعة انزلاق 1m/sec و3m/sec .

This study deals with the friction and wear behavior of coating layers (fluoride and Graphite).The coatings are thermally sprayed on cast iron disks. Sliding is performed between cylindrical pins manufactured from organic brake linings and the coated and uncoated disks. The coatings are characterized by measuring their hardness, porosity, and corrosion resistance. The corrosion resistance of the coating is tested by exposure to Nacl for 150 hours; the coating layer has had the best corrosion resistance. The friction and wear tests are conducted under contact pressures of  (1.5 MPa to 7 MPa) and sliding speeds of 1 and 3 m/sec.
