| 摘 要： | 采用H08A焊芯,研制的TKCE50焊条与传统的高锰钢焊条D256进行对比分析,通过冲击磨损试验,硬度测试及金相显微分析,系统研究了堆焊层的硬度、耐磨性、抗冲击后的加工硬化程度以及各种合金元素对堆焊层性能的影响规律.结果表明,所研制的Fe-Mn-Cr-Mo-V系堆焊焊条具有较高的韧性、抗裂性及优异的加工硬化性能,抗冲击磨料磨损性能十分突出;随着Cr,Mo,V元素含量的增加,堆焊层金属端面硬度增加,达到一定值后,其增加变缓.冲击9 000次后,加工硬化达到极限,此时的堆焊层金属磨损失重最小,耐磨性最好. |
| 关 键 词： | 堆焊焊条 冲击磨损 Fe-Mn-Cr-Mo-V系 |

| Abstract: | Using H08A core wire, the TKCE50 electrode was compared with classical hardfacing electrode D256.The hardness, wear resistance, performance of work-hardening effect after impact and the effect of alloy elements on the hardfacing layers were studied by means of impact wear test, hardness test and microstructure analysis.The results show that the hardfacing electrode with Fe-Mn-Cr-Mo-V alloy system has high toughness, resistance to cracking and work-hardening properties, especially the performance of impact wear-resistantance is excellent.With the increase of contents of Cr, Mo and V, the hardness of hardfacing metal face increases, and when it reached some number, the degree of increasing becomes stable.After impact by 9000 times, the working-hardening degree reached its top, and the worn mass is the lowest and the wear-resistance is the best at this time. |
| Keywords: | hardfacing electrode impact wear Fe-Mn-Cr-Mo-V alloy system |
