摘　　要：采用钎料BNi94SiB980-1065,在钎焊规范为1130℃/10 min的条件下,通过调整工装配重质量,对Z8CND17-04材料第二级扩压器进行真空钎焊;同时,借助金相显微镜和超声波检测仪,分析了真空钎焊前后叶片高度变化、钎缝质量和钎透率。结果表明,当工装配重为56 kg时,钎缝质量较差,零件翘曲达到0.75 mm;随着工装质量的增加,钎缝质量和零件翘曲都有所改善;当工装配重达到94 kg时,叶片高度控制在规定的范围内,获得钎焊接头质量良好,零件翘曲控制在0.5 mm以内,钎透率达到90%以上。Using filler metal BNI94SIB980-1065,the 2nd stage diffuser of Z8CND17-04 is vacuum brazed by adjusting the tooling weight under the brazing specification of 1130℃/10 min.Meanwhile,the change of blade height before and after vacuum brazing,brazing weld quality and brazing penetrate ratio are analyzed by the metallographic microscope and ultrasonic analysis instrument.The results show that when the tooling weight is 56 kg,the quality of the brazing weld is poor and the warping of the part reaches 0.75mm;as the tooling weight increases,the quality of the brazing weld and the warping of the part improve.When the tooling weight is 94 kg and the blade height is controlled within the specific range,the brazing joint quality is good,the warping of parts is controlled within 0.5 mm,and the brazing penetration ratio is over 90%.
