摘要
本文讨论了惯性摩擦焊和连续驱动摩擦焊在连接 SS 316 与 Zn 合金时的效果。利用扫描电子显微镜研究了焊接相互作用的微观结构。能量色散光谱法用于确定界面上元素分布的化学成分。研究结果表明,连续驱动摩擦焊接工艺可以生产出 SS 316 与锌合金的焊接接头。摩擦时间为 35 秒时,接头的抗拉强度可达 60 兆帕。在拉伸试验中,所有摩擦焊接样品都在界面处发生断裂。断裂面几乎是一个平面,没有纤维状或脆性。同时,金属间化合物层的新反应层没有在连接界面上形成。Zn 合金硬度的降低是由于摩擦产生的持续热量导致的热软化效应。
Preliminary study on effect of inertia and continuous friction welding on mechanical properties of SS 316-Zn alloys friction welded joint
The effect of inertial friction welding and continuous drive friction welding in joining SS 316 with Zn alloy is discussed in this article. Scanning electron microscopy was utilized to investigate the microstructure of the welding interaction. Energy-dispersive spectroscopy was utilized to identify the chemical composition of the element distribution at the interface. The findings reveal that a continuous drive friction welding process may produce SS 316 welded joints with Zn alloy. With a friction time of 35 s, the joint's tensile strength may reach 60 MPa. During the tensile test, all friction-welded samples failed at the interface. The fracture surface shows an almost flat surface and is not fibrous or brittle. Meanwhile, a new reaction layer from the intermetallic compound layer is not formed at the joint interface. The decrease in hardness in Zn alloys is due to the thermal softening effect caused by continuous heat from friction.
