This study assesses the viability of producing electrically conductive carbon nanofiber (CNF) reinforced mullite coatings by thermal spraying. Mullite-CNF agglomerated powder was prepared by spray drying and was deposited on steel by atmospheric plasma spraying. The coatings obtained are characterized based on composition, structure, shape, thickness, and electrical conductivity and are compared with coatings produced from commercial mullite powder.
