Abstract: Carbon composite coatings were prepared using an atmospheric pressure plasma spraying on the steel substrate from different feedstock powders. The effect of the various powder types on the surface morphology and structure of the sprayed coatings was investigated. The prepared coatings surface morphology depends on the initial powder morphology and chemical composition. The coating sprayed from the P1 powder (wood waste) demonstrated the lowest surface roughness value. The oxygen concentration in the sprayed coatings increased. The highest oxidation was observed when the graphite flake-like powder (P4) were used. The C/O atomic ratio in the P3 coating (deposited using activated carbon powder), decreased 5.4 times, while the Cu concentration increased 2.4 times compared to the initial powder. The highest specific surface area (~25.94 m2/g) and microhardness value (202 HV) were observed for the coating deposited using P1 powder
