To improve the polishing efficiency of abrasive jet for tungsten carbide (WC) alloy, this paper proposes a stepwise synergistic enhancement method combining photo-Fenton and ultrasonic: the WC alloy is first modified via photo-Fenton reaction, and the modified material is subsequently removed efficiently by an ultrasonic-coupled abrasive jet. In this study, the photo-Fenton modification mechanism was first investigated using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and hardness testing to reveal the evolution of material structure and composition. Subsequently, an erosion model based on Oka theory was constructed to calculate the in-situ erosion behavior of the jet under photo-Fenton and ultrasonic synergistic enhancement, providing a theoretical basis for the subsequent polishing process. Finally, a polishing platform was established, and systematic fixed-point erosion experiments and polishing experiments were conducted focusing on key parameters such as initial roughness, reaction time, and concentration ratio, validating the accuracy of the theoretical calculations and the effectiveness of the polishing method. The results indicate that the photo-Fenton reaction can efficiently modify the WC alloy surface into a granular structure. With the superimposition of ultrasonic enhancement, the maximum jet erosion depth can be increased by more than 9.2 times, and the roughness ( Ra ) optimization efficiency was enhanced by 5.0 times. The proposed photo-Fenton and ultrasonic synergistic enhanced method lays a foundation for efficient abrasive jet polishing, thereby promoting the in-depth application of miniature WC components in industry.
