Seçici lazer sinterleme yöntemiyle üretilen PA 12 matrisli seramik takviyeli kompozitlerin aşınma davranışının incelenmesi

Öz

Bu çalışmada eklemeli imalat yöntemlerinden biri olan Seçici Lazer Sinterleme (SLS) yöntemi kullanılarak seramik takviyeli PA 12 matrisli kompozit malzemeler üretilmiş ve kompozit malzemelerin aşınma davranışları incelenmiştir. Kompozit malzemelerin SLS ile üretilmesinde iki farklı enerji yoğunluğu değeri kullanılmıştır. Üretilen kompozit malzemelere kuru aşınma deneyleri uygulanmıştır. Aşınma testleri 25 mm/sn ve 100 mm/sn hız değerlerinde ve 5 N ile 20 N aşınma yükü değerlerinde uygulanmıştır. Aşınma test yükü arttıkça aşınma oranı artmış, ayrıca kompozit malzeme üretiminde enerji yoğunluğu değerindeki artışın aşınma özelliklerini olumsuz etkilediği belirlenmiştir.
