Twin-wire indirect arc welding is a novel welding process. In this article, the anode wire was an austenite-based welding wire, and the cathode wire was an iron-based wear-resistant welding wire. Given that the two wires burn simultaneously in twin-wire indirect arc welding, a carbide-enhanced austenite-based surface layer was produced. The high-temperature wear resistance of the austenitic stainless steel was enhanced by the carbides. Results indicated enhancements in amount of reinforcing phase in the austenite-based surface layer with increasing of cathode wire feeding speed and the high-temperature friction coefficient decreased first and then increased. However, the corrosion resistance of austenite-based surfacing layer decreased slightly with increasing of amount of reinforcing phase. At low content of the reinforcing phase in the surface layer, the high-temperature wear behavior was dominated by oxidative adhesive wear, which changed to abrasive wear with the increase in the reinforcing phase.
