Tungsten Karbür Besleme Stoğundan Elde Edilen Parçalar İçin İdeal Çözücünün Araştırılması

Bu çalışmada tungsten karbür- kobalt (WC-Co) besleme stoğundan Toz Enjeksiyon Kalıplama (TEK) yöntemi ile elde edilmiş numunelerin kimyasal bağlayıcı aşamasında kullanılacak çözücü türü araştırılmıştır. TEK yöntemi ile WC-Co besleme stoğundan hazırlanan deney numunelerinin kimyasal bağlayıcı giderme deneyleri onüç farklı çözücü (Toluen, Benzen, Heptan, Aseton, Etanol, Karbon tetraklorür (CCl4), Etanol+ Karbon tetraklorür (CCl4), Metanol, Nitrik asit, Hidroklorik asit, Sülfürik asit, Kloroform, Dikloroetan) kullanılarak gerçekleştirilmiştir. Deneyler sonucunda WC-Co besleme stoğu için bulunabilirlik ve maliyet açısından en ideal çözücünün etanol olduğu belirlenmiştir. Ayrıca deneyler sonucunda 60 °C sıcaklık ve 60 saat sürede etanol içerisinde tutulan parçalarda hedeflenen sonuçların elde edildiği belirlenmiştir.

Investigation of The Ideal Solvent For Parts Obtained From Tungsten Carbide Feedstock

In this study, the solvent type used in the chemical debinding process of the samples manufactured from tungsten carbide - cobalt (WC-Co) feedstock by Powder Injection Molding (PIM) method was investigated. Chemical debinding process experiments of the test samples prepared from WC-Co feedstock by PIM method were carried out using thirteen different solvents (Toluene, Benzene, Heptane, Acetone, Ethanol, Carbon tetrachloride (CCl4), Ethanol + Carbon tetrachloride (CCl4), Methanol, Nitric acid, Hydrochloric acid, Sulfuric acid, Chloroform Dichloroethane). As a result of the experiments, ethanol was determined to be the most ideal solvent for WC-Co feedstock in terms of availability and cost. In addition, as a result of the experiments, it was determined that the targeted results were obtained in parts kept in ethanol at 60 °C temperature for 60 hours.
