Toz Enjeksiyon Kalıplama Yöntemi için Üretilmiş Kobalt Esaslı Süperalaşım Besleme Stoklarının Reolojik Özelliklerinin İncelenmesi
Abstract
Toz Enjeksiyon Kalıplama (TEK) gelişmiş bir Toz Metalurjisi (TM) üretim tekniği olup karmaşık geometriye ve dar tolerans aralıklarına sahip parçaların seri üretiminde kullanılan modern bir üretim metodudur. TEK’te kullanılan besleme stoklarının reolojik özellikleri, başarılı kalıplama işlemi üzerinde doğrudan etkiye sahiptir. Bu çalışmada, Co-212-C, Stellite-6 ve Fe50Co0,2Si kobalt esaslı süperalaşım tozları ve çeşitli polimerik bağlayıcılar kullanılarak üç farklı TEK besleme stoğu hazırlanmıştır. Kullanılan tozların besleme stoklarındaki kritik toz yükleme değerleri ve reolojik özellikler üzerindeki etkisi farklı sıcaklıklarda rotasyonel reometre cihazı kullanılarak incelenmiştir. Kullanılan tozların morfolojisi taramalı elektron mikroskobu (SEM) ile analiz edilmiştir. Hacimce %2,5’luk artışla %57,5-65 toz yükleme aralığında elde edilen besleme stoklarının TEK tekniği için temel gereksinimlerden biri olan psödoplastik akış davranışı sergilediği görülmüştür. Ayrıca yüksek toz yüklemelerindeki besleme stoklarının sıcaklığa karşı yüksek hassasiyet gösterdiği, düşük toz yüklemesi ve yüksek kayma hızı kombinasyonunun ise düşük viskoziteye ve bunun sonucunda toz ve bağlayıcının ayrışmasına neden olacağından TEK için uygun olmadığı görülmüştür.
