    摘要:

    研究了Al2O3p／6061Al復(fù)合材料在氬氣保護(hù)下爐中釬焊的可行性。研究表明，采用合理的釬料和釬劑組合(HL401 QJ201)以及正確的釬焊工藝參數(shù)可獲得質(zhì)量良好的釬焊接頭。通過對(duì)接頭的剪切強(qiáng)度和顯微硬度試驗(yàn)以及對(duì)接頭的金相觀察、X射線衍射相結(jié)構(gòu)和斷口掃描電鏡觀察等微觀組織結(jié)構(gòu)分析，從理論上探討釬焊接頭形成過程的機(jī)理，為如何獲得高質(zhì)量的釬焊接頭提供理論參考。

    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.
