摘要
通过高温硬度、高温磨损试验，研究了铁基Ｃｒ－Ｍｏ－Ｗ－Ｖ－Ｎｂ系高温耐磨料磨损等离子弧粉末堆焊合金，可以替代价格昂贵的镍基和钴基等离子弧堆焊合金。同时系统地研究了合金元素及其硬质相在高温磨损中的行为及堆焊合金的抗磨性。即Ｃｒ７Ｃ３［（Ｃｒ，Ｆｅ）７Ｃ３］、Ｃｒ３Ｃ［（Ｃｒ，Ｆｅ）３Ｃ］、ＷＣ、Ｗ２Ｃ、ＮｂＣ、ＶＣ硬质相对堆焊层的组织、硬度和耐磨性的影响规律。结果表明：硬质相的形态、数量和大小不同对堆焊层的抗磨性影响不同。
Through the tests of high temperature hardness and wear resistance,the properties of iron-base Cr-Mo-W-V-Nb system plasma arc surfacing alloy high temperature abrasive wear resistance are investigated.This alloy can replace the expensive Nichel-base and Cobalt-base plasma arc surfacing alloys.The wear-resistance of surfacing alloys and behavior of hard phase in high temperature are investigated systematically,i.e.the effect of hard phases,such as Cr7C3 ,Cr3C ,WC,W2C,NbC and VC,on microsturcture,hadness and wearability of the surfacing layer has been studied.The results prove that the different shape,amount and size of the hard phase have different effect on the wear-resisting of the surfacing layer.\=
