Bu çalışmada, katkısız poliamid 6 (PA 6) termoplastik polimeri ile katı yağlayıcı vaks katkılı poliamid 6 karışımının, kuru kayma şartları altında kendi üzerlerindeki tribolojik performansları incelenmiştir. Katı yağlayıcı vaks/poliamid 6 polimer karışımı ikiz vidalı endüstriyel amaçlı bir ekstruderde üretilmiş, test numuneleri ise enjeksiyon makinesi kullanılarak kalıplanmıştır. Tribolojik testler, ASTM G99 standardına uygun olarak yapılmıştır. Aşınma ve sürtünme testleri, pim-disk aşınma cihazında gerçekleştirilmiş olup 10N, 20N, 30N, 50N, 75N, 100N, 200N ve 250N yüklerde ve 0,5 m/s kayma hızında gerçekleştirilmiştir. Tribolojik test sonuçlarına göre, katı yağlayıcı vaks karıştırılmış poliamid 6 polimerinin kendi üzerinde çalışması durumunda sürtünme katsayısı ve aşınma oranı özelliklerinin katkısız poliamid 6’ya göre daha iyi olduğu tespit edilmiştir. Katkısız poliamid 6 ve katı yağlayıcı vaks katkılı poliamid 6 karışımının aşınma yüzey mikro-yapıları incelemek için optik mikroskop kullanılmıştır.
