Abstract

A tungsten carbide–cobalt (WC–Co) composite layer was formed on a stainless-steel type 304 (SS304) substrate using multibeam laser metal deposition (LMD) with blue diode lasers. This paper aims to provide WC–Co layer formation with low porosity and high layer formation efficiency by using the multibeam LMD process. The effects of process parameters such as laser output power and powder feed rate are tied together to explain the geometry of the melt layer as well as the fraction of the laser energy used for melting a material. The experimental results show that the porosity rate and layer formation efficiency were recorded at 0.3% and 0.0042 mm3/J, respectively, at the laser output power of 180 W and a powder feed rate of 75 mg/s. It was revealed that layer formation efficiency was dependent on the laser output power.

利用蓝色二极管激光器进行多波束激光金属沉积的 WC-Co 合金层形成过程的实验评估

使用蓝色二极管激光器的多波束激光金属沉积（LMD）工艺在不锈钢 304（SS304）基材上形成了碳化钨-钴（WC-Co）复合层。本文旨在利用多波束激光金属沉积 (LMD) 工艺，实现低孔隙率和高效率的 WC-Co 层形成。将激光输出功率和粉末进给率等工艺参数的影响结合起来，解释了熔化层的几何形状以及熔化材料所使用的激光能量分量。实验结果表明，在激光输出功率为 180 W、粉末进料速率为 75 mg/s 时，孔隙率和熔层形成效率分别为 0.3% 和 0.0042 mm3/J。实验结果表明，层形成效率取决于激光输出功率。
