摘　　要：对6063铝合金钎焊接头金相试样进行手工磨平、磨光和机械抛光,再以不同的侵蚀剂分别侵蚀不同的试样表面,然后进行宏观、微观分析比较,结果发现经0.5%氢氟酸溶液和混合酸水溶液侵蚀后的试样,均能清晰地显示钎焊接头显微组织,效果较好。值得一提的是试样的磨平、磨光、抛光及侵蚀过程须一气呵成。The preparation of metallographic specimens for 6063 aluminum alloy brazed joint was introduced including manual rubdown, polishing,mechanical polishing and etched with different agent. The metallographic examination shows that the metallographic specimens etched by 0. 5% hydrofluoric acid solution or mixed acid water solution can display the microstructure clearly. Especially the process of rubdown, polishing and corroding should be gotten done without any letup.
