 Havacılık ve savunma
sanayilerinde kullanılan birçok parçanın üretiminde talaşlı imalat yöntemi
yaygın olarak kullanılmaktadır. Bu yöntem kullanılarak gerçekleştirilen imalat
süreçlerinde meydana gelen termal ve mekanik etkiler imal edilen malzemelerde
mikroyapısal dönüşümlere sebep olabilmekte olup bu durum nihai ürünün yorulma
ömrü, korozyon direnci ve fonksiyonel performansını etkileyebilmektedir. Bu
çalışmada 15-5 PH çelik malzemesinin kriyojenik talaşlı imalat sürecinin yüzey
bütünlüğü karakteristiklerine etkileri deneysel olarak incelenmiştir. Elde
edilen bulgular kuru ve kesme sıvısı kullanılarak yapılan talaş kaldırmadan
elde edilen bulgularla karşılaştırılmıştır. Düşük kesme hızlarında kriyojenik soğutma
yöntemi ile gerçekleştirilen deneyler neticesinde mikroyapıda plastik deformasyon
ve bunun sonucu olarak mikrosertlik artışı meydana gelmiş, kriyojenik koşullar
altında kesici takımda meydana gelen lokal kırılmalar diğer kesme yöntemlerine
oranla daha pürüzlü bir yüzey oluşumuna neden olmuştur.
