摘要
介绍了Fe-Cr-C系耐磨堆焊合金的主要用途,综述了近年来的研究成果以及将来的发展方向。分析表明,初生M7C3垂直于堆焊层表面、多元合金的强化、硬质相呈弥散分布并与基体组织良好的强韧性匹配、不同磨损工况条件堆焊层强韧关系的合理选择能使耐磨效果达到最佳。特殊工况的Fe-Cr-C系堆焊材料的开发及其特种堆焊技术将成为未来研究的新趋势。
The main application of the Fe-Cr-C wear-resistant surfacing alloy system is introduced, the recent research achievements and the future development direction are reviewed. Analysis shows that the primary M7C3 per- pendicular to the surface, multiple alloys strengthening, hard alloy strengthening phase is diffuse distribution and good matching with matrix organization, different wear condition hardfacing layer with reasonable relationship selection, can make to achieve the best effect of wear-resisting. The development of special wear condition Fe-Cr-C wea-resistant surfacing materials system, and special surfacing technology will become the new trend of the future research.
