摘要

采用焊条电弧焊，在COSTE耐热钢和Stellite6合金之间堆焊ENiCrFe-3镍中间层，COSTE钢/Stellite6合金堆焊板作为对比试样，利用扫描电镜、X射线衍射仪、冲击试验机和有限元软件等表征手段，研究ENiCrFe-3中间层对COSTE钢/Stellite6合金堆焊板的成分、组织和冲击性能的影响。结果显示：ENiCrFe-3中间层与COSTE钢和Stellite6合金之间冶金结合良好，在堆焊试样中并没有引入新的脆性相；COSTE/Stellite6堆焊板的冲击功为28 J，加入ENiCrFe-3中间层后，堆焊板的冲击功提高到55 J；ENiCrFe-3中间层的断裂模式为韧性断裂，Stellite6合金的断裂模式为脆性断裂，ENiCrFe-3中间层能够减少堆焊板界面处的残余内应力值。

Abstract

The manual arc welding method is used to overlay the ENiCrFe-3 nickel interlayer between COSTE heat resistant steel and Stellite6 alloy, and the COSTE steel/Stellite6 alloy surfacing plate is used as the comparison sample. The effect of ENiCrFe-3 intermediate layer on the composition, microstructure and impact properties of COSTE steel/Stellite6 alloy surfacing plate was studied by means of scanning electron microscope, X-ray diffractometer, impact testing machine and finite element software. The results show that the intermediate layer of ENiCrFe-3 has a good metallurgical bonding with COSTE steel and Stellite6 alloy, and no new brittle phases are introduced in the surfacing samples; The impact energy of the COSTE/Stellite6 surfacing plate is 28 J, and after adding the ENiCrFe-3 intermediate layer, the impact energy of the surfacing plate increased to 55 J. The fracture mode of the ENiCrFe-3 intermediate layer is ductile fracture, while that of the Stellite6 alloy is brittle fracture. The ENiCrFe-3 nickel intermediate layer can reduce the residual internal stress value at the interface of the surfacing plate.
