The objective of this work is to obtain a multifunctional ceramic composite material at low cost with improved properties and that can be used in many structural applications like: electrical, refractory support tribological elements. A mullite-alumina were prepared by using Algerian kaolin amorphous aluminum hydroxide as starting materials. Two mixtures varying the content 61.5% 50 wt %. an ab...

An optimized recipe for 3D printing of Mullite-based structures was used to investigate the effect MgO sintering additive on processing stages and final ceramic properties. To achieve dense 3:2 mullite, filaments were prepared based an alumina powder, a methyl silicone resin, EVA elastomeric binder powder. Using 1 wt% dwell time 5 h at 1600 °C, mullite structure could be obtained from with diam...

Partially stabilized zirconia (PSZ) agglomerate toughened alumina has been prepared by the "deflocculation-flocculation" technique, using 2 and 3 mol. % Y2O3-doped zirconia powders. Samples containing up to about 30 vol.% zirconia were obtained. The resulting microstructure seems to be mainly influenced by the physical properties of the starting powders, e.g. agglomerate size and the specific s...

A series of microstructured, supported platinum (Pt) catalyst films (supported on single-crystal yttria-stabilized zirconia) and an appropriate Pt catalyst reference system (supported on single-crystal alumina) were fabricated using pulsed laser deposition and ion-beam etching. The thin films exhibit area-specific lengths of the three-phase boundary (length of three-phase boundary between the P...

Ceramics long history in biomedical field is related to their high biocompatibility and mechanical properties. Precisely, for joint replacements, wear resistance fundamental, so advanced ceramics as alumina zirconia are preferred. Developments ceramic additive manufacturing allow dense parts with improved properties shape accuracy. This paper focuses on the tribological analysis of stereolithog...
