| 摘 要： | 通过在Fe-Cr-C系药芯焊丝中加入不同含量TiB2粉末,制备TiB2强化高硬度高耐磨堆焊自保护药芯焊丝.借助光学显微镜、扫描电镜和X射线衍射等手段,试验研究了其堆焊合金显微组织,并考察TiB2含量对该堆焊合金性能的影响.结果表明,堆焊合金组织为初生碳化物、马氏体和残余奥氏体,同时堆焊合金中生成了大量TiC-TiB2颗粒,并且弥散分布在初生碳化物和基体上；TiB2强化耐磨堆焊药芯焊丝的堆焊合金比不加TiB2具有更高的硬度和更好的耐磨性.

| Abstract: | New types of self-shielded flux-cored wire for hardfacing with high hardness and abrasion resistance reinforced by TiB2 were produced by adding different amounts of TiB2 into the Fe-Cr-C flux-cored wire. The effects of TiB2 content in fluxcored wire on the microstructure and mechanical properties of resultant hardfacing layers were investigated by means of optical microscope(OM),scanning electron microanalysis(SEM) and X-ray diffractometer (XRD). The results show that the microstructure of hardfacing layer consisted of primary carbides,martensite and retained austenite,and TiC-TiB2 particles,which dispersed in the primary carbides and matrix,were synthesized via metallurgy reaction during arc welding. The hardfacing alloys reinforced with TiB2 had higher hardness and better wear resistance than that without TiB2. |
