      abstract     = {This work presents a comprehensive evaluation of three
                      industrially relevant coating processes – atmospheric
                      plasma spraying (APS), wet powder spraying (WPS), and
                      electrophoretic deposition (EPD) – for the application of
                      MnCo1.9Fe0.1O4 (MCF) spinel-based protective layers on solid
                      oxide cell (SOC) interconnects. Using Crofer-type ferritic
                      stainless steels as substrate, the coatings were assessed
                      with respect to their technical performance and
                      environmental impact. Microstructural characterization,
                      topography analysis for relevant interconnect structures,
                      and mid-term exposure tests at 800 °C in air confirm that
                      all three methods can produce uniform, well-adhering, and
                      protective coatings compatible with SOC stack integration.
                      While APS serves as a technologically mature reference, the
                      suspension-based techniques WPS and EPD demonstrate
                      comparable protective functionality after suitable thermal
                      treatments. Furthermore, life cycle assessment reveals
                      significant sustainability benefits for the newer methods
                      – especially EPD – due to lower energy demand and
                      enhanced material efficiency. The results highlight WPS and
                      EPD as promising, environmentally advantageous alternatives
                      for large-scale application of protective interconnect
                      coatings in SOC systems.},
