Abstract

In this study, the fabrication process parameters of laser directed energy deposition (LDED) B₄C/Al composites that can achieve the maximum relative density were obtained via Taguchi method. The single-track experiments were employed to determine the appropriate range of laser power, scanning speed, powder feeding speed and protective gas flow rate. Based on the values of these process parameters, an L₁₆ orthogonal experiment was designed using the Taguchi method, and the signal-to-noise (S/N) ratio analysis and analysis of variance (ANOVA) were performed to obtain the LDED process parameters that can achieve the B₄C/Al composites with maximum relative density. And the regression equation and fabrication of bulk composite were adopted to verify the effectiveness of the optimized process parameters. The optimal combination of process parameters was laser power of 1600 W, scanning speed of 350 mm/min, powder feeding speed of 2.0 r/min, and protective gas flow rate of 8.5 L/min. This study will help to establish an effective process for fabricating B₄C/Al composite using LDED.
