| Abstract | The combined laser has been applied in laser processing due to the accelerated damage behavior and processing efficiency. However, the best-combined scheme is uncertain for C/SiC composites due to multiple ablation modes and damage effects at various input laser parameters. In this paper, the combined laser, composing the continuous-wave and short-pulsed or long-pulsed lasers, is experimentally investigated in terms of the efficiency of ablation behavior. An in-situ observation system is established to obtain the instantaneous ablation process. The numerical simulation procedure, which includes an efficient and phenomenological multi-scale ablation model, is also proposed to reveal the ablation mechanism of the combined laser. The experimental and numerical results reveal the governing ablation mechanism of the different composed schemes: When combined with continuous-wave laser, the short-pulsed laser induces the plasma impact effect can reduce the oxidation resistance of the 2D C/SiC-Ti3SiC2 composite, whereas the long-pulsed laser can significantly accelerate the ablation rate. The multi-scale ablation model in this work can provide an effective analytical tool for studying the efficient processing mechanisms of the combined laser. |
