Aiming at improving the impact wear-resistant performance of metals, a new sort of surfacing electrode named TKCE50 was developed in this paper. This electrode is a Fe-Mn-Cr-Mo-V alloy system and belongs to iron-base wear-resistant materials. Tests like hardness, wear loss and impact-abrasion test were performed on the samples surfaced with the electrode. The results indicated that TKCE50 had not only good welding technological properties, but also super work-hardening effect and perfect impact wear-resistance. In addition, the work-hardening and wear-resistant mechanisms for this electrode were discussed based on corresponding experimental investigation and theoretical analysis.
