Abstract
BNi82CrSiBFe brazing material was used for vacuum brazing of 1215 free cutting steel and 302 stainless steel dissimilar metals,and the interface structure and joint properties of the joint were studied.The experimental results show that using BNi82CrSiBFe brazing material and maintaining a constant compression force can achieve high-temperature vacuum brazing of 1215 free cutting steel and 302 stainless steel dissimilar materials.Under the conditions of brazing temperature 1 050℃and insulation for 10 minutes,the tensile strength of the joint can reach over 335 MPa,and under a pressure of 10.5 MPa,the joint has good sealing performance with no penetration.关键词
