| 摘 要： | 利用中间添加Ni层,在610℃保温60min工艺成功实现了SiCp/2014Al铝基复合材料的真空扩散焊接.焊接之后利用金相显微镜(OP)、扫描电镜(SEM)、电子探针(EPMA)等对焊接接头进行分析.分析表明,Ni和Al之间相互扩散形成由金属间化合物构成的中间过渡层,主要由Ni3Al//NiAl//NiAl3组成.在理论上,计算出Ni和Al元素扩散浓度与焊接温度和保温时间之间的关系,以及元素的扩散距离与焊接参数之间的关系呈抛物线形变化.

| Abstract: | SiC_p/2014Al aluminum matrix composite was welded by vacuum diffusion welding technique using Ni as the interlayer metal.The welding joint was analyzed by means of optical microscope(OP),scanning electron microscopy(SEM),and electron probe microanalyser(EPMA).The analysis results indicated that Ni and Al were inter-diffused and there were intermetallic compounds formed in the inter transition layer,which was composed by Ni_3Al//NiAl//NiAl_3.The relation between the Ni,Al diffusion concentration and the welding temperature and the keeping time was calculated.The parabolic relationship between the diffusion distance and the welding parameters was found. |
