| 摘 要： | 采用钛、铌、钒、硼等铁合金与石墨等材料的混合粉,用TiC,B_4C硬质合金与F101,F314等自溶合金制成混合复合材料,以等离子转移电弧为热源进行了探索性的耐磨堆焊材料的试验研究。通过堆焊时的冶金反应,在堆焊金属中形成了TiC,NbC,VC等碳化物超硬质相,极大的提高了堆焊金属的硬度和耐磨性。试验数据表明,这种堆焊金属的耐磨性均超过国内目前F31,堆667,堆717堆焊材料的耐磨性,为堆焊材料领域开发新型材料提供了新的途径。

| Abstract: | The abrasive-resistance of surfacing materials were studied by the mixed powder of iron alloy of Ti,Nb,V,B and graphite with heat resource of plasma transfer arc. The hardness and abrasive-resis tance of the surfacing metals were gratly increased by the super-harden phase of carbide such as TiC, NbC,VC etc. which were formed in the surfacing metals. The test results show that the abrasive-resis tance of this kind of surfacing metal surpasses that of surfacing materials such as F314,D667,D717 which are used domesticly,and it create a new way to develop new materials in the scope of surfacing material. |
