自蔓延高温合成焊接是自蔓延高温合成技术的一个新的应用领域,利用自蔓延高温合成反应放出的热量及产物来实现同种或异种材料的焊接。影响自蔓延焊接的因素很多,本文利用优化出的反应原料组成和工艺参数进行焊接实验,用扫描电镜观察粉末体系与钛的焊接情况,发现平滑的钛管内壁发生变形,焊接界面结合紧密。 Self-propagating high-temperature synthetic welding is a new field of application of SHS synthesis technology, which utilizes the heat released from the high temperature synthesis reaction and the product to achieve the welding of the same or different materials. There are many factors that affect SHS. In this paper, the welding experiment was conducted by using the optimized composition of raw materials and process parameters. The welding conditions of the powder system and titanium were observed by SEM. The inner wall of smooth titanium tube was found to be deformed and the welding interface was tightly bonded.
