 摘要: 为了探索一种新的高效堆焊技术,采用型号为YJ501-1的氧化钛型CO2气体保护药芯焊丝对低碳钢表面进行了双丝堆焊,并利用金相显微镜、扫描电子显微镜、电子能谱分析仪和显微硬度计等分析方法对堆焊层以及堆焊层与基体之间的界面组织、成分和性能进行分析研究。试验结果表明,利用双丝高效堆焊技术可以在金属表面制备一层结构致密、性能优越、结合牢固、稀释率低的堆焊层。

 Abstract: A new two-wire overlaying method was explored in order to improve the overlaying efficiency. The two-wire overlaying was carried out using YJ501-1 Titanium oxide type flux-cored wire under the protection of CO2 gas. The optical microscope,scanning electron microscopy,energy dispersive spectrometer and microhardness tester was used to analyze the microstructure,composition and property of the overlaying layer and the interface between the overlaying layer and base metal. The experimental results showed that a overlying layer with compact structure, superior performance, firmly bound and low-dilution was obtained after two-wire overlaying.

 Key words: flux-cored wire; two-wire overlaying; efficient overlaying; dilution
