“…The characteristics of the friction layer that forms during PoD sliding between the mating surfaces determine the friction and wear behavior of the materials under study [38][39][40]. In the following, we will first focus the discussion on the reference OM material, and then we will consider the effect of the removal of copper fibers (material 0Cu) and their substitution with the same amount of steel fibers (material 0Cu_Fe).…”

“…investigated on the use of the pin-on-disc test to simulate off-brake friction and wear characteristics of friction materials [11,14] and reciprocating sliding test set-up [18][19]. Morphological analysis [13] , correlation among temperature variation [16][17] , tribological evaluation of rubber resin bonded brake pad materials [19] were examined for its commercial applicability. In order to rank critical properties for a selection of brake pad materials amongst all, an Analytic Hierarchy Process (AHP) was used by Bachchhav et.…”

Nevertheless, asbestos though having ample physical and tribo-mechanical properties is being banned worldwide due to its health hazardousness. Most importantly, any material replacing asbestos should have comparable friction properties. This paper aims at comparative study of frictional characteristics of asbestos base and asbestos free brake pad materials. A total of three friction materials namely AF-22 (metallic based), CL-3003 (fine brass based) and DM-6 (asbestos based) were compressed and moulded into a sample. Experiments were performed using dedicated test set-up based on Pin-on-disc principle. Coefficient of friction was compared for three materials at different conditions of sliding velocity and pressure. Experiments were performed using Taguchi’s L27 orthogonal array. Ranking of the parameters have been done based on experimental results and S/N ratio analysis. The elemental composition of materials was measured by EDS technique. Scanning electron micrographs of brake pad samples were tested at different magnifications. Further investigations to evaluate wear rate, stopping distance under simulative test conditions are suggested.

“…Balata kompozitini oluşturan bu malzemelerdeki çeşitliliğin nedeni, sürtünme katsayısını kararlı tutmak, iyi bir aşınma direnci sağlamak ve her durumda güvenilir bir frenleme performansı elde etmektir [4,5]. İyi bir frenleme performansının yanı sıra kullanılan malzemelerin çevre dostu olmasının da önemi artmaktadır [3,[6][7][8]. İçeriğinde çevre dostu malzemeler olan sürtünme malzemelerinin, tribolojik testlerinin yapıldığı çalışmalar literatürde mevcuttur [8][9][10].…”

Bu çalışmada, Renault Clio otomobilin fren balatası, bor oksit tozu katkısı ile sıcak presleme yöntemiyle üretilerek, bor oksit tozunun balatanın tribolojik özellikleri üzerine etkisi deneysel olarak araştırılmıştır. Son yıllarda çevre dostu malzemelerin kullanılmasının önem kazanmasından dolayı fren balatasının içeriğinde bor oksit kullanılmıştır. Ayrıca bu malzemenin seçilmesinde ülke ekonomisine fayda sağlamakta amaçlanmıştır. Karşılaştırma yapmak için ticari Clio balatası kullanılmıştır. Balata numunelerinin aşınma sürtünme deneyleri Chase tipi cihazda yapılmıştır. Bor oksit katkısının fren balatasının aşınma sürtünme performansına etkisi ticari fren balatasının sonuçlarıyla kıyaslanarak incelenmiştir. Sonuçta bor oksit katkısının sürtünme katsayısına olumlu etki yaptığı gözlenmiştir.
