在条件相同情况下，利用合金硼化物代替合金碳化物作为耐磨合金的耐磨相，既可进一步提高耐磨合金的硬度和耐磨性，还可减少其它贵重、稀缺合金元素的加入量。本文在排除其它合金元素影响的情况下，研究了不同硼含量对Ｆｅ－Ｃ－Ｂ耐磨堆焊合金的组织及性能的影响。研究表明，随着堆焊合金中硼含量增加，堆焊合金组织发生变化，组织中先后出现了作为耐磨相的Ｆｅ３（Ｃ，Ｂ）、Ｆｅ２３（Ｃ，Ｂ）６和Ｆｅ２Ｂ等碳、硼化物，随着其数量的增加，堆焊合金的硬度和耐磨性显著提高，其共晶组织具有最佳的抗冲击韧性。对研究含硼耐磨合金堆焊焊条提供了理论依据。
In the same conditions, the use of alloy borides instead of alloy carbide wear-resistant alloy wear-resistant phase can not only improve the hardness and wear resistance of wear-resistant alloys, but also reduce the amount of other precious and rare alloying elements. In this paper, excluding the influence of other alloying elements, the effects of different boron content on the microstructure and properties of Fe-C-B hardfacing alloys were studied. The results show that with the increase of boron content in the surfacing alloy, the structure of the surfacing alloy changes. In the microstructure, carbon and boron, such as Fe3 (C, B), Fe23 (C, B) With the increase of its quantity, the hardness and wear resistance of the surfacing alloy increase significantly, and its eutectic structure has the best impact toughness. Provide a theoretical basis for the study of boron-containing wear-resistant alloy surfacing electrode.
