摘要

摘要: 增材制造技术具有设计自由度大、无需模具、可近净成形的优点,在航空航天、海洋工程、石油工程等领域有着广阔的应用前景。然而,以钛合金为代表的高强合金由于其热导率低、充型能力差的本征属性,导致激光成形构件易出现气孔、热裂纹、冷裂纹等成形缺陷,从而降低其力学性能。近年来,为了深入挖掘成形缺陷形成的微观机理,研究人员研发了多种缺陷的表征技术,并在此基础上开发了缺陷修复技术。本研究从缺陷三维表征和电脉冲修复技术两个角度出发,总结了目前成形缺陷三维无损表征技术和无损修复技术的进展,并对未来激光增材制造成形件的缺陷分析和修复技术进行了展望。

Abstract: Additive manufacturing technology has the advantages of large design freedom, no need for dies, and near net forming, so the technology has broad application prospects in aerospace, ocean engineering, petroleum engineering and other fields. However, due to the low heat conductivity and limitation of mold-filling capacity of high-strength alloys such as titanium alloys, their laser-formed components are prone to form defects such as pores, hot cracks, and cold cracks, which will reduce their mechanical properties. Recently, in order to dig out the micro-mechanism of forming defects, researchers have introduced several characterizing methods for analyzing the defects. In addition, on the basis of the results from the defects characterizations, technologies have been generated for repairing defects. In this article, we summarize the development of non-damaged three-dimensional characterizing technologies for forming defects, as well as the non-damaged defects repairing technologies. In the end, we also indicate the prospect of defects analysis and reparation for the components by laser additive manufacturing.
