TiC/NiCr金属陶瓷与1Cr13不锈钢的真空钎焊

Vacuum brazing between TiC NiCr cermets and 1Cr13 stainless steel

  • 摘要: 以CuMnNi和CuMnCo合金为钎料,采用真空钎焊方法实现了TiC/NiCr金属陶瓷与1Cr13不锈钢的牢固连接。研究了钎料类型及钎焊工艺对钎缝接头力学性能与微观结构的影响。结果表明,采用CuMnNi钎料时在1050℃保温30min的钎焊工艺下获得了最高界面抗剪强度为338MPa,而采用CuMnCo钎料时在1050℃保温60min的钎焊工艺下获得了最高界面抗剪强度为274MPa,剪切断口发生在金属陶瓷靠近钎缝侧。良好的界面扩散互溶是获得较高界面连接强度的主要原因。并通过扫描电镜(SEM)、X射线衍射分析等方法对钎焊接头微观组织、剪切断口进行了观察和分析。

     

    Abstract: Firm joints were obtained between TiC/NiCr cermets and 1Cr13 stainless steel with CuMnNi and CuMnCo fillers by vacuum brazing. Effects of fillers and brazing parameters on mechanical properties and microstructures of brazed joints were investigated. Results revealed that the maximum shear strength of brazed joints (338MPa) can be achieved at 1050℃ for 30min by the use of CuMnNi filler, and maximum value (274MPa)at 1050℃ for 60min by the use of CuMnCo filler.Brazed joints are fractured on cermets near the side of fillers. Excellent mutual solution was the main reason of achieving firm brazed joints. SEM, XRD were used to evaluated the joint microstructures and fracture morphology.
