摘　　要：采用BNi82CrSiBFe钎料对1215易切削钢和302不锈钢异种金属进行真空钎焊,并对接头界面组织及接头性能进行了研究。试验结果表明:采用BNi82CrSiBFe钎料、保持恒定压紧力的作用下,可以实现1215易切削钢与302不锈钢异种材料的高温真空钎焊;钎焊温度1050℃,保温10 min,得到的接头抗拉强度可达到335 MPa以上,在10.5 MPa的压力下接头密封性良好,无渗透。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 1050℃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.
