摘要

摘要本文对激光金属沉积技术在NiCuBSi型金属粉末简单部件生产中的工艺参数进行了验证。采用同轴供粉和氩气的激光头进行生产。将粉末焊接到S235J2G3钢板上。所使用的参数(热输入0.25 kJ.mm−1)使样品具有最小的孔隙率(1.2%)，并且在焊接层之间没有缺陷(冷接头，气孔)。

Use of Laser Metal Deposition Technology in Additive Manufacturing of Ni Powder Materials

Abstract The process parameters of the Laser Metal Deposition technology in the production of simple components made of NiCuBSi type metal powder were verified in this paper. A laser head with a coaxial powder supply and argon gas was used in the production. The powder was welded to a S235J2G3 steel plate. The used parameters (heat input 0.25 kJ.mm−1) enabled the production of samples with a minimum porosity (1.2 %) and without the defects (cold joints, pores) between the weld layers.
