Optimal coating compositions deposition parameters for the air and fuel side (D3.2)
This is deliverable reports the optimized PVD parameters for composites coating on fuel and air electrode interconnectors.
PVD or more specifically magnetron sputter deposition is a well-known and mature method for obtaining high quality thin film coatings. It has been used to make coatings for many applications, such as optical, wear resistive, tribological and protective coatings.
In all cases, the quality and properties of the thin film layers can be tailored by adjusting sputtering parameters.
The most important parameters being gas pressure, bias voltage, substrate temperature and the reactive gas partial pressure, if oxide or nitride layers are deposited.
Within the scope of PilostSOEL project, NACO Technologies has worked on adjusting the deposition parameters in order to obtain dense, stable in high temperature, conductive protective coatings of Ni (fuel side) and MnCOx composites (air side) for interconnector plates.
