In this study, Cr₂O₃, Cr₂O₃-SiO₂-TiO₂ and Cr₂O₃-SiO₂-TiO₂-graphite coatings were formed by atmospheric plasma spraying. The influence of SiO₂-TiO₂ and SiO₂-TiO₂-graphite reinforcements on the surface morphology, elemental composition, structure and tribological properties of chromia coatings was determined. The friction coefficients and specific wear rates were investigated by a ball-on-flat configuration using 1 N and 3 N loads under dry-lubrication conditions. The addition of SiO₂-TiO₂-graphite resulted in the lowest surface roughness and the most homogenous surface of the coatings. The X-ray diffraction (XRD) measurements demonstrated that all as-sprayed coatings consisted of an eskolaite chromium oxide phase. The results showed that the Cr₂O₃-SiO₂-TiO₂ coating demonstrated the lowest friction coefficient values. The SiO₂-TiO₂ and SiO₂-TiO₂-graphite additives reduced the specific wear rates of Cr₂O₃ coatings by 30% and 45%, respectively. Additionally, the wear resistance was improved almost 45 times in comparison to the steel substrate.
