| 中文摘要: |
| 为修复高锰钢零件在中低载荷作用下的磨损失效,在 D256 焊条药皮中加入一定量的钛铁、钒铁、碳化硼和稀土元素,采用手工电弧的方法,通过焊接冶金反应自发生成硬质增强颗粒,并且通过后续热处理改变硬质相在高锰钢堆焊层中的分布,以提高堆焊层耐磨性。 分析了堆焊层的显微组织和力学性能。 结果表明:与D256 焊条堆焊层相比,添加 12% Ti-Fe +12% V-Fe +6% B4C 的堆焊层组织晶粒明显细化,且有一些细小的颗粒第二相生成,其硬度达到了 53 HRC;经过固溶时效处理后,堆焊层的组织更为细小,碳化物分布更为均匀,虽然硬度值下降到 49 HRC,但耐磨性有所提高。 |
| 英文摘要: |
| In order to fix low-loads wear failure of high manganese steel components , D256 electrode coating were added with a certain amount of ilmenite, vanadium iron, boron carbide and rare earth elements, by the method of manual arc welding, metallurgy reaction spontaneously generated hard reinforced particles to change the distribution of the hard phase in the high-manganese steel surfacing layer, and by subsequent heat treatment to improve the wear resistance of the surfacing layer. Results show that: compared with the D256 electrode surfacing layer, adding 12 % Ti-Fe +12 % V-Fe +6 % B4C to the D256 electrode surfacing layer provides finer grain size, as well as some fine second phase hard particles, whose hardness is 53 HRC, and these particles are more evenly distributed and finer after solution and aging, while its hardness reduces to 49 HRC, its wear-resistance improves comparatively. |
