Bd des Forges TroisRivières QC GZ M Canada Hydrogen Research Institute Full time $60,000 - $120,000 per year
Company Description

Our mission is to advance science and technology for the establishment of a sustainable energy system using Hydrogen particularly in the field of production, storage, safety, and utilisation. The Institute for Hydrogen Research (IHR) is a multidisciplinary team of over 50 people having at its disposal state of the art equipment and laboratories.

Laboratories at the IHR specializes in design, synthesis, characterization and testing of novel materials, materials and energy system modelling, to system engineering and system integration for renewable energy, transport and stationary applications.

Job Description

The temperature of the cryolite bath is crucial data for the operation of aluminum electrolysis cells. Currently, it is measured punctually because thermal probes (thermocouples) corrode quickly in the cryolithic bath and therefore cannot be used continuously.

We aim to significantly increase their life by designing new alloys that provide excellent corrosion resistance. Developing a durable probe would thus allow for better control of the electrolysis process. To do this, we will develop a new generation of protective coatings based on alloys produced by mechanosynthesis and deposited by thermal spraying. This project will bring together university and industry researchers with complementary expertise in materials science, high-temperature electrochemistry, thermodynamic modeling as well as in the production of protective coatings by thermal spraying and in the production of primary aluminum.

The doctoral student will be responsible for the design of metal alloys using thermodynamic simulation tools (such as FactSage). He/she will be responsible for i) identifying new families of alloys likely to be more resistant to corrosion et to produce them, ii) studying their theoretical and experimental resistance to degradation by fluorinated salts and by oxidation at high temperature and iii) determining the corrosion phases that will be formed. The selected person will work with a team of experts in applied electrochemistry and materials synthesis. In addition, the project is carried out in collaboration with two industrial partners, including one of the world's leading aluminum producers.

Qualifications

Master's degree in chemistry, chemical engineering, metallurgy, materials science or other relevant discipline. Knowledge of thermodynamics and/or corrosion in a molten salt environment. Experience in aluminum or metal corrosion will be considered an asse
