Abstract

In the present study, Cr2O3 nanostructured and conventional (MICROSTRUCTURED) coatings have been prepared by atmospheric PLASMA SPRAYING (APS) on carbon steel substrates. Phase composition and structural properties of coatings were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Also, the mechanical properties of coatings such as MICROHARDNESS were evaluated. Nanostructured Cr2O3 coating exhibited a bimodal microstructure consisting of nanosized particles retained from the powder and microcolumnar grains formed through the resolidification of the molten part of powder, whereas the microstructure of conventional Cr2O3 coating consisted of columnar-grain splats. The results revealed that nanostructured coating, due to unique microstructure container of nanozones, presented improved MICROHARDNESS and fracture toughness as compared to the conventional coating.
