Missions

The Physical Chemistry of Surfaces Research Group (PCS) of the Institut de Chimie Paris (IRCP, CNRS / Chimie ParisTech) is looking for highly motivated candidates for a post-doctoral position directed to the understanding of the growth mechanisms of oxide films (native oxide, passive films) on metallic alloys (stainless steel, high entropy alloys) containing chromium and molybdenum.

Activities

In order to carry out this work, the candidate will use a combination of experimental techniques to correlate alloy reactivity (characterized by electrochemical measurements) to chemical nature of surface oxide layers (characterized by advanced surfaces analysis by Time of Flight Secondary Ions Mass Spectrometry (ToF-SIMS) and X-ray Photoelectron Spectroscopy (XPS)). An original approach, based on isotopic tracers (D2O, 18O2, H2O18) combined to ToF-SIMS measurements, will be used to characterize the growth of oxide layers, the role of hydroxylation and possible hydrogen penetration.
The task of the selected candidate will include the preparation of surfaces, the performing of electrochemical measurements and the interpretations of XPS and ToF-SIMS results. Other tasks will include the presentation of data to supervisors, the preparation of reports, and the publication of results in scientific journals.

Skills

-knowledge in surface analysis, corrosion and electrochemistry.
-fluent English (oral and written)

Work Context

The Physical Chemistry of Surfaces Research Group (PCS) of the Institut de Chimie Paris (IRCP, CNRS / Chimie ParisTech) study the corrosion process of metals and metallic alloys based on a chemical and structural characterization of surfaces and interfaces at atomic and nanometric scales and the correlation between these mechanisms and the reactivity of these alloys and their durability in specific environments.

The post-doctoral student will benefit from the assistance of CNRS research engineers.

Additional Information

Applicants must send their Curriculum Vitae, cover letter and two letters of reference. Only complete applications will be considered. Candidates will be pre-selected based on their academic excellence for an interview in Paris or by visioconference.
