| 摘 要： | 采用超声气体雾化法制备了Ni—Cr—Co—W—Mo—B中间合金钎料，利用XRD，DSC和SEM分析了钎料的微观结构、固液相线的温度及瞬态液相(TLP)连接接头的成分。研制的液态钎料对镍基高温合金基体具有良好的润湿性。连接后的试棒在1073K下的拉伸强度为1123MPa，1283K／248MPa下的持久寿命为43h.TLP连接后经固溶时效处理，接头区域的成分和组织与基体一致，性能与母材相当.

| Abstract: | Ni-Cr-Co-W-Mo-B powder as a brazing filler was prepared by gas atomization, and its microstructure and melting characteristics were determined by XRD and DSC. The micro-structure and composition analyses across the bonded interlayer were performed by SEM. The wettability between Ni-Cr-Co-W-Mo-B alloy and Ni-based superalloy substrate is good. The bond tensile strenghth at 1073 K and stress rupture at 1283 K/248 MPa are 1123 MPa and 43 h respectively. After transient liquid phase bonding and heat treatment, the microstructure and composition of the joint zone resemble those of the superalloy substrate, and the joint properties are almost identical to those of the superalloy substrate. |
