In718 Süperalaşım Tozunun Enjeksiyon Kalıplanabilmesi İçin İskelet Bağlayıcı Polipropilen Kullanılarak Hazırlanan Besleme Stoklarının Reolojik Özelliklerinin İncelenmesi
Abstract
Yapılan çalışmada, özellikle uzay endüstrisinde yaygın olarak kullanılan IN718 tozunun hatasız toz enjeksiyon
kalıplanabilmesi (TEK) için en uygun reolojik özellikleri belirlenmiştir. İskelet bağlayıcı olarak Polipropilen
kullanılarak üç farklı bağlayıcı kürü ile %61, 63 ve 65 (%hacimce) toz yükleme oranlarında besleme stokları
hazırlanmıştır. Besleme stokları içerisinde bulunan IN718 tozunun ortalama parçacık boyutu 13,40 mikrondur.
Kullanılan bağlayıcılar (Polietilenglikol, Parafin Wax, Carnauba Wax, Stearik Asit ve Polipropilen) 3 boyutlu karıştırıcıda kuru olarak 30 dakika karıştırılarak bağlayıcı kürleri hazırlanmıştır. Elde edilen besleme stoklarının reolojik özellikleri kılcal reometre kullanılarak karakterize edilmiştir. Yapılan deneysel çalışmalarda sıcaklık ve basınca bağlı olarak besleme stoklarının kayma gerilmeleri (
