Investigation Of Composite Part Production From WC-Co/HSS Using Nickel Interlayer By Inserted Powder Injection Molding Method
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2018, Vol 6, Issue 2
Abstract
It is possible to produce small parts with geometric precision from high density metal, ceramic, composite and intermetal materials by powder injection molding (PIM) methot. In order to produce bigger parts, the prepared component called the insert is placed in the mold and powder injection molding is carried out on it. This method is named inserted powder injection molding (IPIM). The IPIM is a good method that can be used for the production of parts from different materials as well as for the production of larger parts. In this study, part production was investigated using HSS insert, Ni interlayer and WC-Co (9%) feedstock by IPIM method. The effects of sintering temperature and duration, linear shrinkage in the feedstock and shear strength between the two materials were examined. The linear shrinkage ratio increases with increasing temperature and time, and the maximum linear shrinkage at the injected part at 1250 ° C for 360 minutes is found as %15.92. At 1200 ° C temperature and 120 minutes of sintering time, the highest shear strength obtained with the sample using 100 μm Ni interlayer is 114 MPa.
