Instability development at the interface of viscous heterocharged fluids

The proposed studies will relate to a low Reynolds laminar flow of a two-dimensional mixture layer of a highly viscous dielectric fluid. The fluid / fluid interface will be studied experimentally under different conditions. This subject is part of action 5.1 of the INTERACTIVES labex, action which concerns the manipulation of internal flow by electrical discharge and charge injection.

Master 2 internship -Filled- Multi-interstitials compounds: a new way in surface properties optimization of Titanium alloys

This position is filled. The proposed internship will focus on the determination of the diffusion parameters involved in the treatment of (pure) Titanium and the TA6V alloy. Oxi-nitriding treatments with gas enriched with 18O and 15N isotopes will be operated the plasma assisted thermochemical treatment reactor of the Physics and Mechanics Department (DPMM) of the P’ Institute. Various parameters will be investigated such as the microstructure of the modified surface, the crystallographic structure, the characterization of the isotopes profiles of the dedicated samples and the determination of the diffusion mechanisms. The applicant is expected to have motivation and skills in experimental characterization of materials and surfaces.
