摘要:The TiC-VC particles reinforced surfacing layer synthesized from ferrotitanium, ferrovanadium and graphite through metallurgy interaction by novel twin electrodes welding arc had been investigated in this paper. The microstructure and abrasion resistance of surfacing layer were analyzed by XRD, SEM and wear test machine. The results showed that Ti element mainly acted as deoxidize due to the unique twin electrodes welding arc structure, only a small quantity of TiC was formed in the surfacing layer. The main reinforcing phases in surfacing layer were in situ VC, as well as a litter (Ti, V) C phase dispersed in matrix. The surfacing layer had higher surface rigidity of exceeded 55 HRC and better abrasion resistance property. Wear weight loss of surfacing layer was only 1/16 of that of Q235 substrate.
