Abstract

In this study, the effect of the addition of different ratios of colemanite (0.5-4 %) on tribological properties of bronze based brake lining material containing 6 % fly ash fabricated by hot pressing method were investigated. The friction-wear tests of produced brake lining materials were performed on a Chase type friction tester according to SAE J661 test standard. Furthermore, some of physical properties such as density and hardness were also determined. Wear surface of samples were characterized by using scanning electron microscopy (SEM) and X-ray diffraction (XRD) to determine the wear mechanism. Wear resistance and friction coefficient values of all the brake lining specimens were found to be in the range specified in SAE-J661 standard. In terms of wear resistance, the best result was found for brake lining material without colemanite addition while 0,5 % colemanite added sample gave the best result in terms of friction coefficient

Özet

Bu çalışmada sıcak presleme yöntemi ile üretilen kütlece % 6 uçucu kül takviyeli bronz matrisli fren balata malzemesinin tribolojik özellikleri üzerine farklı oranlarda (% 0,5-4) ilave edilen kolemanit miktarının etkisi araştırılmıştır. Üretilen balata malzemelerinin sürtünme aşınma deneyleri SAE J661 test standardına göre Chase tipi test cihazında gerçekleştirilmiştir. Ayrıca sertlik, yoğunluk gibi bazı fiziksel özellikler de belirlenmiştir. Aşınma mekanizmasını belirleyebilmek için numunelerin aşınma yüzeyleri taramalı elektron mikroskobu (SEM) ve X-Işını Kırınım yöntemi (XRD) kullanılarak karakterize edilmiştir. Deneysel çalışma sonucunda bütün balata numunelerinin aşınma direnci ve sürtünme katsayısı değerleri SAE-J661 standart aralığında çıkmıştır. Aşınma direnci açısından en iyi sonucu kolemanit ilavesiz sürtünme malzemesi verirken, sürtünme katsayısı açısından en iyi sonucu % 0,5 kolemanit ilaveli sürtünme malzemesi vermiştir.
