【摘要】 采用真空热压扩散连接法制备出冶金结合的钢铜铝复合材料,采用电解腐蚀法对所制备的复合材料从铜侧进行分层腐蚀,并结合扫描电镜（SEM）、能谱分析（EDS）和X射线衍射（XRD）对所腐蚀德连接界面的各个扩散层进行了形貌、成分、相分析。结果表明:铜/铝界面,从铜侧到铝侧以次为铝在铜中的固溶体,CugAl₄和CuAl2;不锈钢/铜界面为铜在不锈钢中的固溶体。研究得到了适用于本实验条件下的铝铜金属间化合物生长方式。更多还原

【Abstract】 The vacuum warm compaction diffusion method is used to prepare the Al/Cu/0Cr18Ni9Ti composite; electrochemical corrosion is used to gradation etch the Cu and the interface of Al/Cu; and further the scanning electron microscopy（SEM）,electron probe microanalysis（EPMA）and X-ray diffractometer（XRD）are used respectively to analyze the gradation etched interface.The following results are obtained: under the condition of two steps diffusion bonding,the composite is well bonded with the joint less than 9μm of intermetallic compound in the Al/Cu joint,1.5μm solid solution formed in the Cu/0Cr18Ni9Ti diffusion zone; through the four stages growth,two kinds of intermetallic compound formed in the interface of Al/Cu,Cu₉Al₄ adjacent to the Cu side and CuAl₂ adjacent to the Al side.The growing model of Al/Cu intermetallic compounds is found suitable for the condition of the experiment by this study.更多还原
