For a period of one year, I worked at IBS (International Biomedical System) a biomedical manufacturing company as an R&D Engineer. My project task was to finalize the recipe to deposit a ceramic layer on the surface of a coronary stent, the main company product.
The goal of the company was to develop an industrial repeatable process to synthesize a nanometric layer of Titanium Nitride through a Chemical Vapor Deposition process. This complex chemical reaction takes place in a ultra high vacuum chamber (less than 100 nanopascal), where nitrogen gas is fluxed and excited through a magnetic field into a plasma. The magnetic field is generated by two high purity Titanium plates, which function as a source of atom to form a new ceramic compound with the Nitrogen.
For this assignment, I worked in close collaboration with the Biology Department of the University of Trieste, where I performed visual analysis and structural tests of the grains with a SEM (Scanning Electrons Microscope).
The next gallery shows some pictures of the ceramic structures. Each picture is a SEM image with a scale reference.
