Topological characterisation of very porous materials

An innovative route has been developed to model very porous materials, such as abradable deposits.

SEM micrographs of coatings sections give information about the different phases present in the structure (matrix, dislocator and porosities) and their morphology.

Equivalent images are then produced, replacing particles and porosities by ellipses, which help to:
- Simplify the picture and the mesh,
- Characterize geometrically each inclusion, allowing statistics on them,
- Restore the effective three-dimensional geometry of the coating.
