Assessment of Failure Strength of Real Alumina Foams with Use of the Periodic Structure Model [PDF]

Archives of Metallurgy and Materials, 2018
The subject of the study are alumina foams produced by gelcasting method. The results of micro-computed tomography of the foam samples are used to create the numerical model reconstructing the real structure of the foam skeleton as well as the simplified

Gelcasting ceramic defense parts [PDF]

, 1997
The goal of this work was to demonstrate an ability to gelcast and fire a particular defense-related part to net shape and to hold the required tolerances on size and shape with minimal or no post firing machining. The precision required represents a huge increase in the precision currently achievable by standard ceramic processing.

Gelcasting of alumina

, 2005
Ispitan je savremeni postupak oblikovanja keramičkih prahova, "livenje geliranjem", eng. gelcasting, zasnovan na konceptima polimerne hemije i klasičnog postupka livenja. Postupak obuhvata livenje stabilne suspenzije pripremljene sa velikom količinom čvrste faze (keramički ili metalni prah) i rastvorom organskih monomera, monofunkcionalnog i ...

Effect of emulsion composition on gel strength and porosity in the preparation of macroporous alumina ceramics by freeze gelcasting

Journal of Asian Ceramic Societies, 2015
The freeze gelcasting of hydrogenated vegetable oil-in-aqueous alumina slurry (HVO-in-AAS) emulsions of HVO to AAS volume ratios in the range of 1.34–2.69 prepared from slurries of various alumina concentrations were studied to prepare macroporous ...

Porous Si3N4 Ceramics Prepared by Gelcasting Route and Pressureless Sintering at Different Temperatures

Materials Research
In this work, the gelcasting method was used to prepare porous Si3N4 ceramics, using sodium lauryl sulfate and Isobam 110 as foaming and gelling agents, respectively. Samples sintered at different temperatures were characterized by mercury porosimetry, X-

Corrosion in 316L Porous Prostheses Obtained by Gelcasting

Procedia Materials Science, 2015
AbstractGelcasting (GC) process, usually used for ceramic moulding, is adapted for producing spongy or porous metal osteosynthesis components destined to bone void filling. The main objective of the interconnected porosity is to improve the osteoconductive of metal matrix by ingrowth of bone.
