Abstract:: Powder injection molding (PIM) is a net fabrication technique that combines the complex shape-forming ability of plastic injection molding, the precision of die-casting, and the material selection flexibility of powder metallurgy. For this study, the design issues related to PIM for fabrication of thin-walled high-aspect ratio geometries were investigated. These...
Resource Type:: Masters Thesis
Full Text:: K. Paul for being a part of my committee and providing me invaluable guidance for my thesis work

Creator:: Martin, Renee A.
Abstract:: Mullite-zirconia composites have been slated for use in a novel miniature ceramic turbine engine components developed for unmanned air vehicle (UAV) engine applications. Economically feasible production of these complex components requires the use of a near-net shape process such as powder injection molding (PIM). This thesis explores the development and...

Full Text:: Viscosity versus shear rate at 413 K (top) and 440 K (bottom) for varying volume fractions of zirconia-rich

Creator:: Kate, Kunal H.
Abstract:: Ceramic injection molding (CIM) is a high volume, near net shaping process used to manufacture ceramic parts with complex features and shapes. In CIM design it is important to understand the molding behavior as a function of powder-polymer (feedstock) composition in order to achieve desired part dimensions and properties, at...

Creator:: Laddha, Sachin
Abstract:: Micro Powder injection molding (μPIM) is a cost-effective technique for producing small, complex, precision parts in high volumes from ceramic and metal nanoparticles. This study focuses on research conducted on fabrication of Micro Ceramic Arrays (MCAs) parts using μPIM. MCAs are widely used as the major components and design features...

Creator:: Lenz, Juergen H. (Juergen Herbert)
Abstract:: A new material system was developed for fabricating the combustion engine of an unmanned aerial vehicle. The material system consisted of a mixture of nanoscale and microscale particles of silicon nitride. Magnesia and yttria were used as sintering additives. The powders were mixed with a paraﬃn binder system. The binder-powder...

Creator:: Chinn, Richard E.
Abstract:: Silicon carbide is an important and versatile nonoxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding--removal of...
