Abstract

Laser metal deposition (LMD) is an additive manufacturing (AM) technologies in that belongs to the class of direct energy deposition which is suitable for manufacturing of alloys and composites materials. LMD is an efficient AM technique which is capable of producing end-use products starting from depositing the powder/wire material layer-by-layer. During LMD process, a laser beam is used as a heat source to generate a melt-pool on the substrate and melts the powder that is deposited through a co-axial nozzle and supported with a shielding gas that helps to prevent oxidation. LMD is capable of producing complex shaped and functionally graded parts which are useful in many industrial applications. This AM technology can also be used in repairing worn out parts that cannot be repaired by other manufacturing technology. In this paper, a review of laser metal deposition of titanium alloy is presented. This provides an overview of LMD of titanium alloys grade 5 (Ti6Al4V) and focuses on the effects of processing parameters on the overall evolving properties.

激光金属沉积钛合金Ti6Al4V的研究进展

激光金属沉积(LMD)是一种增材制造(AM)技术，属于直接能量沉积的范畴，适用于合金和复合材料的制造。LMD是一种高效的增材制造技术，能够从逐层沉积粉末/线材开始生产最终用途产品。在LMD过程中，激光束用作热源，在基材上产生熔池，并熔化通过同轴喷嘴沉积的粉末，并由有助于防止氧化的保护气体支撑。LMD能够生产复杂形状和功能梯度的零件，在许多工业应用中都很有用。这种增材制造技术还可以用于修复其他制造技术无法修复的磨损部件。本文综述了钛合金激光金属沉积的研究进展。概述了5级钛合金(Ti6Al4V)的LMD，并着重讨论了工艺参数对其整体性能的影响。
