On the Study of Mechanical Properties of Aluminum/Nano-Alumina Composites Produced via Powder Injection Molding
Powder Injection Molding (PIM) is a precision manufacturing process used for production of advanced composites. Mixing of polymeric binder with metal powders, molding of feedstock, de-binding of brown parts and sintering of green samples are four main steps of this process. In the present study, the compounds containing multi-component binder system and aluminum/ nano-alumina (0-9 wt.%) powders...
متن کاملBiocompatibility Study of a Hydroxyapatite-Alumina and Silicon Carbide Composite Scaffold for Bone Tissue Engineering
Received: 12/Jul/2008, Accepted: 14/Oct/2008 Objective: To date, several scaffolds have been fabricated for application in bone tissue repair. However, there remains a need for synthesis of scaffolds with better mechanical properties, which can be applied to defects in weight-bearing bones. We constructed a composite ceramic bioscaffold of hydroxyapatite-alumina and silicon carbide (HA-Al2O3SiC...
متن کاملInfluence of the formulation of an alumina powder on compaction
The compression of ceramic powders requires the addition of organic materials to insure tablet cohesion. For the compaction of formulated ceramic powders it is necessary to supply them energy. As a function of the formulation of ceramic powders, one can measure the specific energy acquired during the tablet compression. Recently, a technique used in powder metallurgy, High Velocity Compaction (...

متن کاملSynthesis and Characterization of Silver and Gold Nano-Structures on Chitosan-Porous Anodic Alumina Nano-Composite
This study was designed to probe the fabrication of unique silver and gold nano-structures engaging a self-designed chitosan-porous anodic alumina nano-composite as a template. Porous anodic alumina has been manufactured by di-step aluminum anodization in an oxalic acid electrolytic bath. The surface properties of porous anodic alumina were reinforced by chitosan neutralized in sodium hydro...
