Development processes of Fe-Al/Cr 3C 2 cored wires were introduced, coatings were in-situ synthesized using Fe-Al/Cr 3C 2 cored wires and high velocity arc spraying (HVAS) technology; Merits of cored wires used in high velocity arc spraying were illustrated; Influences of added Cr 3C 2 reinforcement on coatings' information and compounds change were discussed; Properties of iron aluminum coatings were investigated. Results show that high velocity arc spraying coatings abtained by using Fe-Al/Cr 3C 2 cored wires had relatively high bond strength and micro-hardness, excellent high temperature erosion resistance and room-high temperature wear resistance.
