Job Description
Thesis Subject
Development and characterization of a surface texturing process using pulsed micro-discharges
Your Work Environment
The proposed PhD project is part of the MINITL program (ANR-25-CE51-3871), which started in January 2026. This project aims to develop and optimize a micrometer-scale surface texturing process based on thermochemical treatments performed using arrays of cold microplasmas. In this context, the objective is to demonstrate the feasibility of localized nitriding of metallic surfaces, such as AISI 316L steel, using these plasma sources. The control and understanding of the generated plasmas, together with device lifetime, constitute key scientific and technological challenges to be addressed. Ultimately, this study aims at achieving controlled and positive micrometer-scale structuring of metallic surfaces through thermochemical treatment without the use of masks.
Overall, the MINITL program brings together four partner laboratories, including LPGP and IJL, which offer complementary expertise. This allows the project to combine experimental aspects, such as the fabrication of micro-discharges, their characterization using advanced plasma diagnostics, plasma-based surface treatments, and surface characterization, with theoretical work focused on the modeling of such discharges.
The PhD topic proposed here contributes to several tasks within the MINITL program and focuses on the study of MHCD-type (Micro-Hollow Cathode Discharge) micro-discharges, fabricated at LPGP, in N₂–H₂ mixtures. The objective is to determine their properties and optimize them, particularly in terms of lifetime (plasma diagnostics: OES, imaging, electrical measurements, etc.), as well as to apply these sources to nitriding treatments and to characterize the treated surfaces.
