| 摘 要： | 设计了Fe-Cr-Ti-Nb-V-C系堆焊层金属，并与Fe-Cr-W-Mo-C系进行对比，利用扫描电镜（SEM）、透射电镜（TEM）分析了堆焊层的组织，利用MM200型磨损试验机进行耐磨性对比，通过磨损面形貌观察，探讨了磨损机理。结果表明，由于形成弥散的MC型碳化物第二相及强韧的基体，Fe-Cr-Ti-Nb-V-C系堆焊层金属具有良好的耐磨性。

| Abstract: | A welding surface layer of Fe-Cr-Ti-Nb-V-C alloy system was designed, and their microstructure and wear resistance were examined using SEM, TEM and MM200 wear testing machine respectively. Based on the morphologies of wear surface, the wear mechanism was analyzed. It was indicated that the welding deposited metal of Fe-Cr-Ti-Nb-V-C alloy system showed good wear resistance due to the formation of dispersed MC type carbides and tough low carbon martensite matrix. |
