    Effect of micro and nano-sized ZrSiO4 particles on the friction and wear properties of polymer matrix composites
    (Walter De Gruyter Gmbh, 2022) Sugozu, Banu; Daghan, Behcet; Akdemir, Ahmet; Sugozu, Ilker
    In this study, the size effect of zircon (ZrSiO4) on the tribological characteristics of polymer matrix friction composites were investigated. Hence, four friction composites containing micro and nano-sized zircon particles (5 and 10 wt%) were developed and produced using powder metallurgy method. Their wear and friction characteristics were examined using a friction-wear test device. The weight loss and specific wear rate were measured and compared with that obtained for microsized zircon particles. The surfaces of samples were analyzed using a scanning electron microscope, and less wear was observed in the samples containing nano-sized zircon particles. The results revealed that the size of abrasive particles plays a key role in enhancing the friction coefficient and friction stability.

    Effect of the size on the friction characteristics of brake friction materials: a case study with Al2O3
    (Emerald Group Publishing Ltd, 2018) Sugoezue, Banu; Daghan, Behcet; Akdemir, Ahmet
    Purpose The purpose of this paper is to study the potential of alumina (Al2O3) in nanometer size in automotive brake friction materials. Design/methodology/approach Four brake linings containing alumina differing in particle size (355 mu m and 80 nm) and various amount (5 and 10 Wt.%) were designed and produced. The hardness, density and porosity of the samples were measured. All samples were tested on a full-scale brake dynamometer with gray cast iron disc to determine the tribological properties. Detailed examinations on the worn surface were analyzed using a scanning electron microscopy. Findings It was concluded that all performance parameters were beneficially affected because of nano alumina. Originality/value This paper emphasizes the importance of nano-composites in the automotive industry and helps industrial firms and academicians working on wear of materials.
