Main project: Optimisation of the corrosion rate of iron-based alloys for bioresorbable stent applications
Funding: FRIA
Supervisor(s): Pascal Jacques

The purpose of this PhD thesis is to optimise the metallic surface of iron-based alloys that are good candidates for bioresorbable stents but which corrosion properties are still insufficient. I will thus be working on these alloys by improving their surface properties, by acidifying the surface. Indeed, the corrosion products and salt compounds get deposited due to a neutral/basic environment in the close vicinity of the metal surface. These compounds act as a barrier for further corrosion. By acidifying the metallic surface, this would inhibit, or at least diminish, the deposition of these compounds. The corrosion properties of these metals will be studied by the use of electrochemical tests as well as immersion tests. The surface will be acidified by the presence of protons. This will be done by adding hydrogen in the metal. Nevertheless, the presence of hydrogen is known to weaken the metal. In order to avoid this weakening, the hydrogen will be trapped inside the steel.

This project englobes different disciplines and is made alive thanks to close collaboration with different entities of the UCL.
