PREPARATION AND CHARACTERIZATION OF DISPERSION COMPOSITE CERAMICS FOR THERMO-MECHANICAL USES.

Objective

TO DEVELOP OPTIMIZED AL203 - ZR02 DISPERSION COMPOSITES FOR INDUSTRIAL APPLICATION AS A SUBSTITUTE FOR MORE EXPENSIVE COMENTED CARBIDE TOOLS.

AL2O3 - ZRO2

THIS STUDY WILL INCLUDE:

- CHARACTERIZATION OF POWDERS FROM DIFFERENT ORIGINS,
- OPTIMIZATION OF SINTERING AND HOT PRESSING PROCESSES,
- THERMO-MECHANICAL PROPERTY MEASUREMENTS AND THEIR CORRELATION WITH MICROSTRUCTURES.

VARIOUS POWDERS SUCH AS INDUSTRIALLY PRODUCED, PLASMA TORCH AND DOPED TYPES WILL BE INVESTIGATED BY SURFACE BET AND CHEMICAL ANALYSIS. SHAPE FACTORS AND PARTICLE SIZE DISTRIBUTIONS WILL ALSO BE STUDIED. MIXING, MILLING, DISPERSION AND SPRAY DRYING WILL BE LOOKED INTO AT THE POWDER FORMING, FIRING PRESSURES WILL BE INVESTIGATED DURING THE FORMING AND FIRING STAGES. ANALYSIS OF THE HOT PRESSING KINETICS WILL BE COMPUTER MODELLED.

CHARACTERIZATION OF THE SINTERED MATERIALS WILL BE CARRIED OUT PHYSICAL AND MECHANICAL PROPERTIES INCLUDING THERMAL-SHOCK RESISTANCE AND FATIGUE USING THE NON-DESTRUCTIVE ACOUSTIC EMISSION TECHNIQUE. RESEARCH WILL BE CARRIED OUT TO TRY TO UNDERSTAND THE MECHANISMS RESPONSIBLE FOR TOUGHENING OF THE MATERIAL.

THIS WILL BE AN INTEGRATED PROJECT BETWEEN CRIBIC WHO WILL, TOGETHER WITH EMSE, FRANCE, (SUT-110-F) CARRY OUT THE POWDER PREPARATION, THE MIXING STUDIES AS WELL AS THE FORMING, SINTERING AND FIRING OF THE MATERIALS, AND INSA, FRANCE, (SUT-107-F) WHO WILL CONCENTRATE ON PHYSICAL AND MECHANICAL CHARACTERIZATION OF THE OPTIMIZED COMPOSITES.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Data not available

Call for proposal

Procedure for inviting applicants to submit project proposals, with the aim of receiving EU funding.
