Abstract: Fe-Al/ Cr₃C₂coatings were sprayed on low steel by high velocity arc spraying(HVAS) technology. The influences of oxides on erosion, corrosion and wear behavior for high velocity arc sprayed Fe-Al/ Cr₃C₂coatings were studied. The results show that HVAS-sprayed Fe-Al/Cr₃C₂ coatings have good erosion, heat corrosion and wear resistance. The erosion resistance improves with the increase of the temperature. On one hand, the ferrous oxides are incompact, so they peel off the surface of the coatings easily during the high temperature erosion. On the other hand, compact Al₂O₃ films on the surface can protect the coatings.
