Özet
In this study, the abrasive wear behavior of multi-walled carbon nanotube (MWCNT) and graphene oxide (GO) filled polypropylene (PP) nanocomposites without using compatibiliser were investigated. The effects of material type, sliding distance, and emery paper number on the abrasive wear of PP nanocomposites were investigated by adopting a statistical approach. The tribological tests were performed in dry condition using pin-on-disc at 1.0m/s sliding speed and 10N load. The optimization of signal-to-noise ratio (S/N) and degree of significance of the control variables to minimize the wear volume and coefficient of friction was carried out. As a result of the study, wear volume and coefficient of friction increased with increasing sliding distance, while decreased with increasing emery paper number for all tested materials. The coefficient of friction of the MWCNT and GO filled PP nanocomposites decreased by 19% and 23% compared to unfilled PP polymer, respectively. GO filled PP nanocomposites was found to be approximately 95% less wear volume than MWCNT filled PP nanocomposites. The minimized coefficient of friction and wear volume was obtained at 0.3%wt GO filled PP nanocomposite with the parameters of 100m sliding speed and 1200 grid emery paper number with a value of 0.2716 and 3.07 mm3, respectively. © 2021 MIM Research Group.
