Abstract

Havacılık, biyomedikal ve otomotiv endüstrisinde alüminyum alaşımlarının kullanımının yaygınlaşmasıyla birlikte, bu malzemelerin işleme davranışları ve işleme problemleri son yıllarda ilgi konusu olmuştur. Kuru işlemede, alüminyum gibi yüksek plastisiteye sahip (sünek) metaller, takım-talaş ara yüzeyinde geniş temas alanı, yüksek sürtünme katsayısı ve sıvanma (adezyon) özellikleri ve buna bağlı olarak güçlü bir talaş yığılması (BUE) eğilimine sahiptir. Bu çalışmada alüminyum alaşımlarının bu problemine bir çözüm olarak son yıllarda yoğun çalışmaların yapıldığı DLC (diamond-like carbon) kaplamanın performansı Al 7075-T651 alaşımı için incelenmiştir. K10 standardına sahip sinterlenmiş karbür takım, üç farklı kaplama şartlarında (kaplamasız, ticari kaplamalı ve DLC kaplamalı) kullanılmıştır. Çalışmada DLC kaplama işlemi özgün olarak yapılmıştır. Bu takımların Al 7075-T651 alüminyum alaşımının işlenmesi sırasındaki performansı gerçek tornalama testleriyle gerçekleştirilmiştir. Tornalama işleminde talaş derinliği 1,5 mm sabit alınırken, 3 farklı kesme hızı (300, 400, ve 500 m/dk) ve 3 farklı ilerleme hızı (0,2-0,3 ve 0,4 mm/d) seçilmiştir. Talaş morfolojisi ve takım yüzeylerinin detaylı incelemesi yapılmıştır. Sonuç olarak, DLC kaplamanın sıvanma sorununa çözüm olabileceği, ancak kaplama parametrelerinin, kesici takım ve alaşımın sınıfına bağlı olarak optimize edilmesi gerektiği değerlendirilmiştir.
