采用金刚砂作为铝/不锈钢复合管爆炸焊接试验装置中的填充物,并在注水和不注水两种工艺下进行爆炸焊接试验。直观观测,因金刚砂注水后的密实度得到提高,因此复合管的变形量相对较小;采用扫描电镜和能谱仪从微观成分对两种工艺下制备的复合管界面进行比较,结果表明,金刚砂注水爆炸焊接的复合管,不仅其界面为规则的微、小波状结合,且产生的金属间化合物也更少;对注水工艺下制备的复合管结合界面进行力学性能检测,其力学性也完全满足使用要求。 Emery was used as the filler in the explosion welding of aluminum / stainless steel composite pipe, and the explosive welding test was carried out under the two processes of water injection and non-water injection. Intuitive observation shows that the deformation of the composite pipe is relatively small due to the increased compactness of the emery after water injection. Comparing the micro-composition of the composite pipe interface prepared by the two processes by SEM and EDS, the results show that the emery The composite pipe injected with water and explosion welded not only has the regular micro-wave and small wave-like interface but also produces fewer intermetallic compounds. The mechanical properties of the composite pipe bonded interface prepared under the water injection process are also tested, and its mechanical properties are fully satisfied Requirements.
