Ti(C,N)基金属陶瓷与45号钢火焰钎焊试验研究

Study on Torch Brazing of Ti(C,N) Based Cermets to 45 Steel

在火焰钎焊条件下 ,采用铜基、银基钎料对 Ti(C,N)基金属陶瓷与 4 5号钢进行钎焊试验。通过观察和分析钎焊接头的结合情况及剪切试验 ,表明 Ti(C,N)基金属陶瓷具有较好的钎焊性 ;火焰钎焊条件下 ,以 H 6 2为钎料的接头的平均剪切强度为37MPa,以 BAg10 Cu Zn为钎料的接头的剪切强度达 114 MPa,以 BCu Zn Mn为钎料的接头的平均剪切强度为 4

Under torch brazing condition, using brazing filler metals of Cu-based and Ag-based, a series of tests are investigated to braze Ti(C,N) based cermets and 45 steel, the micrographic structure of joints and shearing test results are analyzed, they show that Ti(C,N) based cermets has good brazability. Under torch brazing ,the joint's average shear strength is 37MPa with H62 filler metals, 49MPa with Bcu58ZnMn ,and 114MPa with BAg10CuZn.
