N2 - Nano-structured coating materials become demanding, since it improves the mechanical properties, such as hardness, through grain refinement. One of the methods of producing nano-structured coatings is to use an arc spray coating process using nano-structured wires. Although the arc spraying process is well developed, the influence of nanoparticles on the fracture toughness of the coating surface has not been examined in details. Consequently, in the present study, arc spraying of nano-structured wires on carbon steel surface is carried out. The influence of coating thickness on the microstructure and fracture toughness of the coating is investigated. It is found that the self annealing due to large coating thicknesses has a noticeable effect on the microstructure and fracture toughness.
