陶瓷与金属由于其差异较大的热膨胀系数易导致接头残余应力较大,研究者们采用添加中间层方式,成功降低了接头残余应力。本工作采用AgCu/泡沫Cu/AgCu复合钎料对ZrB_2-SiC陶瓷与Inconel 600镍基合金进行真空钎焊,系统研究了泡沫Cu厚度对钎焊接头组织和性能的影响。结果表明:所获得的钎焊接头无明显缺陷,焊缝均由Agss,Cuss和(Cr,Fe)7C3三种相组成。剪切性能测试表明:添加泡沫Cu中间层获得的接头性能高于未添加泡沫Cu得到的接头,且随着泡沫Cu厚度的增加,焊缝中泡沫Cu骨架结构增多,钎焊接头强度呈先增大后减小的变化趋势。当泡沫Cu厚度为1mm时,接头获得最优的剪切强度,达到72.5MPa。通过ABAQUS有限元分析软件对接头残余应力进行分析,添加泡沫Cu钎焊时,接头金属侧残余应力降低了50.6MPa,ZrB_2-SiC侧降低了110.3MPa,进一步证明添加泡沫Cu能够有效缓解钎焊接头残余应力。 |

Ceramics and metals have large differences in thermal expansion coefficients,which can easily lead to large residual stresses in the joints.The researchers used the method of adding an intermediate layer to successfully reduce the residual stress in the joints.In the present work,using AgCu/Cu foam/AgCu composite filler as interlayer,brazing ZrB_2-SiC ceramics and Inconel 600alloy has been studied.Microstructure,shear strength and residual stress were studied in details for conditions with different thickness of Cu foam.The results show that with or without the addition of Cu foam,the brazed joints consists of Agss,Cussand(Cr,Fe)7C3phases without obvious defects. Shear strength of brazed joint is improved after introducing the Cu foam.With the increase of Cu foam thickness,the Cussis quantitatively increased,and shear strength is increased first and then decreased.When thickness of Cu foam is 1 mm,the maximum shear strength is obtained as 72.5MPa.The residual stresses of joint were calculated by using ABAQUS.The residual stress on the metals side is reduced by 50.6MPa,and the ZrB_2-SiC side by 110.3MPa of the brazed joint with Cu foam.The results further prove that the addition of Cu foam can effectively reduce the residual stress and improve the shear strength of joints. |
