FDM Yöntemi Kullanılarak Üretilen Grafen Katkılı PLA+ Malzemeden Üretilen Numunelerin Çeşitli Sürtünme Ve Aşınma Şartları Altında Tribolojik Davranışlarının Incelenmesi

In the present study, 9 identical samples were produced by using 2% graphene reinforced PLA+ filament by melt deposition modeling (FDM) method. The friction and wear behaviors of the produced graphene-doped samples under different tribological conditions were investigated. In order to create different tribological conditions, the applied load, rotational speed (rpm) and sliding distance were determined as variable parameters throughout the experiments. 3 different levels were selected for each parameter determined as variable. The applied load was determined as 30 – 40 – 50 Newton, rotational speed (rpm) as 200 – 250 – 300, and sliding distance as 100 – 150 – 200 meters. Taguchi L9 array was used in order to reduce the number of experiments in the 3 different parameters and 3 different levels selected. As a result of the experiments performed, it was observed that Sample 1 produced with 30 N load, 200 rpm and 100 meters sliding distance had the highest wear rate and friction coefficient. It was observed that Sample 3, produced with 30 N load – 300 rpm and 200 meters sliding distance, had the lowest wear rate and friction coefficient. In addition, it was observed that the speed parameter was the most effective parameter on the friction coefficient with a delta value of 0.0422, that the parameter levels did not have a linear or consistent increase or decrease effect, and that the speed parameter was the most effective with a Delta value of 0.889 when examined in terms of S / N ratios
