In the present work, transitional wear of atmospheric plasma sprayed Cr2O3 and Cr3C2 coatings on low carbon steel substrate have been investigated with coating thickness of 100μm and 200μm. The produced coated and uncoated mild steel substrate samples were characterized by means of microscopic examinations, hardness and sliding wear tests for varying parameters of load, sliding speed, and sliding distance, SEM analysis were carried out for characterization studies of worn surface of samples. The obtained results revealed that the wear rate was much lower in Cr3C2 coated samples followed by Cr2O3 coated samples on mild steel substrate. When comparison to chromium oxide composite coatings the chromium carbide coatings showed better improved results
