Investigation of The Effect of Solid Lubricant Particle Sizes on Friction and Wear Properties in Friction Composites: An Experimental Case Study with Graphite
Sugözü, İlker | Sugözü, Banu
Friction composites consist of many materials with various properties. Solid lubricant is one of these materials. The task of the solid lubricant in the compo-site is to protect the counter surfaces against wear and to reduce noise and vibra-tion. Typical solid lubricants used in the friction composite are graphite, antimo-ny trisulfide, molybdenum disulfide, copper sulfide, etc. The selection suitable solid lubricants for better braking performance is an important issue, as solid lubricants may decompose at high temperatures, leading to undesirable results. The particle size of the solid lubricant used is at least as important as itself. In this study, the effect of micro and nanoparticle-sized graphite on friction and wear behavior of friction composites was investigated experimentally. ...
Tribological properties of brake friction materials containing fly ash
Sugözü, Banu
Purpose The purpose of this study is to investigate the potential of fly ash in automotive brake lining materials. Design/methodology/approach Three brake linings containing fly ash (36, 41 and 46 Wt.%) were designed and produced by dry-mixing, pre-forming and hot pressing. The surface hardness of all brake lining samples was measured by using Brinell hardness tester. The density of the specimens was determined based on Archimedean principle in water. The friction and wear characteristics of the brake lining samples were determined using a real brake disc-type tester. Detailed examinations on the worn surface were analyzed using a scanning electron microscopy. Findings Fly ash can be good alternative as space filler to reduce the cost for brake lining. Originality/value The present study h...

Tribological and thermal characteristics of copper-free brake friction composites
Sugözü, Banu | Sugözü, İlker
The effects of zinc, steel, aluminum, and brass materials that can be used instead of copper in brake friction composites on braking performance were investigated in this study. The specimens containing three different ratios of metallic shavings were produced by the dry mixing method. In terms of comparison, a total of 16 specimens were examined by producing the specimen containing copper at the same rates and the specimen containing no metallic chip. The weight loss, specific wear rate, and friction coefficient of the specimens were determined by the brake test results. The hardness and density tests were carried out. Thermal conductivity tests of the specimens were carried out to determine the thermal characteristic of copper. Among the metallic chips used, aluminum and steel wool were ...
The effect of ulexite to the tribological properties of brake lining materials
Sugözü, İlker | Sugözü, Banu
Recently, different brake pads have started to be investigated in brake friction industry by replacing the asbestos with new materials. This paper presents the role of Ulexite on friction assessment and screening Test of newly formulated brake pads. Friction coefficient, specific wear ratio, and scanning electron microscope SEM for friction surfaces were examined to assess the performance of brake pads. From the results, they concluded that the friction material containing Ulexite improved friction stability and fade resistance. Further, for heat treated samples they claimed a higher and stable friction coefficient
The Effect of Wearing Brake Lining Surface on Braking Performance
Sugözü, İlker | Sugözü, Banu
After braking, different wear types and micro-macro gaps occur on the brake lining surface. This situation varies depending on the amount of binder, friction modifier, reinforcement, lubricant and filler materials used in the brake lining content and braking conditions. In this study, the effect of brake lining surface morphology, which is worn after braking, on the tribological properties of the brake lining was investigated. In this context, the wearing surfaces of the brake lining after braking were examined. It has been observed that the braking performance increases depending on the rate of wear types seen on the brake lining surface.
