“…The softer materials have higher wear rates compared to the harder materials (Rashad et al, 2015;Altintas et al, 2016;Tabandeh et al, 2016;Çavdar and Akkurt, 2018) in general. The wearing test results in the literature (Rashad et al, 2015;Altintas et al, 2016;Çavdar and Akkurt, 2018) are in accordance with the presented wearing test results. It is illustrated that the 0.8 wt% GNP-Al has better coefficient of friction when compared to other samples.…”

“…Hardness and tribological properties of conventional sintered Al/GNP composites were also investigated in our previous work (Çavdar and Akkurt, 2018). The composites containing same percentage of the GNP concentration in the matrix were sintered at 620 °C for 1 h under an argon environment and then cooled naturally.…”

“…Cavdar and Akurt (2018), Rashad et al (2015) and Khorshid et al (2016) fabricated Al-GNP composites by using nano powders by using conventional sintering method. They investigated the microstructural, mechanical (Çavdar and Akkurt, 2018), electrochemical properties (Rashad et al, 2015) and tribological behaviours (Khorshid et al, 2016) of Aluminium composites reinforced with Graphene NanoPlatelets.…”

Alüminyum Matrisli Kompozitlerde Tungsten Karbür ve Grafen Takviyelerinin Mekanik Özelliklere Etkileri Üzerine Bir Araştırma

“…Altıgen bir kafes yapısı ile karbon atomunun iki boyutlu formu olan Grafen sahip olduğu mükemmel elektriksel özellikler, yüksek ısı iletkenliği, yüksek elastisite modülü, yüksek mukavemet ve süper ince ve hafiflik gibi üstün özellikleri sayesinde şimdiye kadar keşfedilen en güçlü malzemedir [14,24,35,55,62,63]. Grafenin moleküler yapısı ve taramalı elektron mikroskobu görüntüsü Şekil 7'de, fiziksel ve mekanik özellikler Tablo 7'de verilmektedir.…”
