Graphene and graphite were coated on steel plates by means of Electro
Phoresis Deposition (EPD) for electrical conductivity improvement. Thermal
treatment was used after EPD to improve the adhesion between the coating layer
and the steel substrate. The highest value of the electrical conductivity achieved
was 20 times higher than that of the steel substrate. The optimized EPD and
thermal treatment conditions were identified. The coating-steel interface and
surface structure suggested that good bonding between the coating and the
steel substrate was achieved
