Abstract

With the aim of investigating the cladding geometry characteristics by a wide-band fiber laser with coaxial rectangular nozzle, and optimizing the powder efficiency and deposition speed for economy efficiency, Fe-based alloy powder was deposited on AISI 1045 substrate by a 3000 W fiber laser in this study. Laser power (P), scan speed (V), and powder feed rate (F) were selected for a factorial design. The effects of the three process parameters on the geometry characteristics and economic efficiency of single tracks were statistically analyzed, and a linear regression model was established between the combined parameters and the relevant characteristics (including track height, ratio of track width to height, powder efficiency, and deposition speed). A process map was developed with the track shape and key economic indexes as boundaries. A flat-top feature of the track profile was found and can be utilized to achieve good cladding evenness. The process map showed that the powder efficiency and deposition speed were higher than 50% and 20 mm3/s, respectively, when selecting process parameters in the as-built operation window.

宽带光纤激光器激光熔覆工艺参数研究及经济性优化

为了研究同轴矩形喷嘴宽带光纤激光器熔覆层的几何特性，优化粉末效率和沉积速度以达到经济效益，利用3000 W光纤激光器在AISI 1045衬底上沉积了fe基合金粉末。选择激光功率(P)、扫描速度(V)和粉末进料速度(F)进行析因设计。统计分析了3种工艺参数对单轨几何特性和经济性的影响，并建立了组合参数与相关特性(包括轨道高度、轨道宽高比、粉末效率、沉积速度)之间的线性回归模型。以轨迹形状和关键经济指标为边界，绘制了过程图。发现轨道轮廓的平顶特征可以用来实现良好的包层均匀性。工艺图显示，在已建操作窗口中选择工艺参数时，粉末效率和沉积速度分别大于50%和20 mm3/s。
