Aşınma ve sürtünme nedenli ekonomik kayıpların azaltılması için yağlayıcıların kullanılması etkili çözüm yöntemlerinden biridir. Motor yağlarında kullanılan yağ katkı malzemeleri ile yağın tribolojik ve termofiziksel özelliklerinin gelişmesi sağlanmaktadır. Bu çalışmada ZnS nanopartikül sentez parametrelerinden proses sıcaklığı (10 ve 70 °C) ve farklı çözücü (1-PrOH ve EtOH) kullanımı koşullarında elde edilen nanopartiküllerin motor yağına eklendiğinde tribolojik davranışlara olan etkisi araştırılmıştır. Elde edilen sonuçlar; 10 °C de EtOH içerisinde yapılan işlemler ile daha küçük boyutlu nanopartiküller elde edilmiştir. Bu nanopartiküllerin baz yağa eklendiğinde 10W yağa göre; vizkozitenin ve 0–200 °C aralığında termal kararlılığın arttığını ve aşınmanın ortalama %39 azaldığını göstermiştir.

Effect of ZnS nanoparticles synthesis parameters on the improvement of tribological properties

Öz

Using lubricants is one of the effective solution methods to reduce economic losses caused by wear and friction. Lubricant additives used in motor oils improve the tribological and thermophysical properties of the oil. In this study, the performance of the engine oil related to the tribological behavior was investigated when the nanoparticles were obtained under different synthesis parameters such as process temperature (10 and 70°C) and the use of various solvents (1-PrOH and EtOH). The results showed that smaller-sized nanoparticles were obtained under 10°C process conditions and when EtOH was used. Furthermore, when these NPs were added to the base oil, it was found that the viscosity increased compared to 10W oil, the thermal stability was increased in the range of 0-200°C and the wear loss rate decreased by an average of 39%.
