Abstract
Bu çalışmada önce, katkısız poliamid 6 ile
ağırlık olarak %5 ve %10 oranlarında poly-tetra-flor-etilen (PTFE) katkılı
poliamid 6 polimer karışımlarının aşınma ve sürtünme davranışları
incelenmiştir. Polimer karışımları, endüstriyel tip ikiz vidalı bir kompound
makinasında granül formda üretilmiştir. Deneylerde kullanılan test numuneleri
geleneksel enjeksiyon makinası kullanılarak basılmıştır. Katkısız PA 6 ve PA 6
karışımlarının aşınma ve sürtünme davranışları pim-disk aşınma cihazında ve
kuru kayma şartları altında gerçekleştirilmiştir. Katkısız PA 6 ve PA 6/PTFE
karışımlarının aşınma ve sürtünme davranışları 0.5m/s kayma hızında ve 10N, 20N
ve 30N yükler altında yapılmıştır. Çalışma sonucunda, PA 6 polimerine ilave
edilen PTFE katkı, polimer karışımının hem sürtünme katsayısı hem de spesifik
aşınma hızı değerlerinin azalmasına sebep olmuştur. Uygulanan yükün artması ile
sürtünme katsayısı değerleri azalırken spesifik aşınma hızı değerleri de
artmıştır.
