| 摘 要： | 研究了Al2O3p／6061Al复合材料在氩气保护下炉中钎焊的可行性。研究表明，采用合理的钎料和钎剂组合(HL401 QJ201)以及正确的钎焊工艺参数可获得质量良好的钎焊接头。通过对接头的剪切强度和显微硬度试验以及对接头的金相观察、X射线衍射相结构和断口扫描电镜观察等微观组织结构分析，从理论上探讨钎焊接头形成过程的机理，为如何获得高质量的钎焊接头提供理论参考。

| Abstract: | The feasibility of Al2O3p/6061Al composites materials brazing in resistance furnace protected by argon gas is investigated. Results show that the brazed joint with good quality can be got by using the reasonable brazing filler metal and proper brazing flux (HL401+QJ201) and the optimum brazing technological parameters. The mechanical properties of brazed joint, such as shearing strengthen and microhardness have been tested, and the microstructure analyses such as metallographic observation, XRD and SEM, have been done to discuss the mechanism of the brazed joint forming in theory, providing some information on how to get excellent brazed joint. |
