| 目的 研究不同钎料钎焊Haynes 214合金与GH5188合金钎焊界面的熔蚀现象。方法 针对Haynes 214合金蜂窝与GH5188合金板材的焊接需求，使用HBCo51CrNiSiW、HBNi71CrSi和B-Ni73CrSiB-40Ni-S 3种不同钎料进行钎焊工艺实验，并对钎焊界面进行组织和成分分析。结果 当采用B-Ni73CrSiB-40Ni-S钎料进行钎焊时，钎焊界面显示出良好的组织均匀性，并未出现熔蚀现象。当使用HBCo51CrNiSiW和HBNi71CrSi 2种钎料进行钎焊时，于Haynes 214合金蜂窝根部产生熔蚀，且HBCo51CrNiSiW钎料对Haynes 214合金蜂窝的熔蚀程度更严重。进一步分析表明，产生这种熔蚀现象的主要原因为，在高温钎焊过程中，钎料与母材之间发生了元素扩散，钎料中的Si元素不断向母材扩散，与母材形成了低熔点共晶相，造成母材熔蚀。结论 B-Ni73CrSiB-40Ni-S钎料在钎焊Haynes 214合金蜂窝与GH5188合金板材时表现出更优异的性能，能够有效防止母材熔蚀问题的发生。 |

| The work aims to study the erosion of the brazing interface between Haynes 214 alloy and GH5188 alloy with different filler metals. To meet the welding needs of Haynes 214 alloy honeycomb and GH5188 alloy plates, the brazing process tests were conducted with three different brazing filler metals of HBCo51CrNiSiW, HBNi71CrSi and B-Ni73CrSiB-40Ni-S and the microstructure and composition of the brazing interface were analyzed. When B-Ni73CrSiB-40Ni-S was adopted as the brazing filler metal, the brazing interface microstructure showed good uniformity and no signs of erosion were observed. When HBCo51CrNiSiW and HBNi71CrSi were used as filler metals, the erosion was found at the root of the Haynes 214 alloy honeycomb, and the degree of erosion caused by the HBCo51CrNiSiW filler metal to the Haynes 214 alloy honeycomb was more severe. Further analysis revealed that this erosion was mainly due to element diffusion between the brazing filler metal and the base metal during the high-temperature brazing process. The Si element in the filler metal continuously diffused into the base metal, forming a low-melting eutectic phase with the base metal, resulting in the erosion of the base metal. Based on the above analysis, B-Ni73CrSiB-40Ni-S brazing filler metal exhibits superior performance in welding Haynes 214 alloy honeycomb and GH5188 alloy plates, effectively preventing the occurrence of base metal erosion. |
