Abstract

Enhancing the surface properties of Ti6Al4V has become a key area of study in advanced materials, particularly for aerospace and medical applications. This study investigates the synergistic effects of combining ultrasonic vibration with laser polishing on Ti6Al4V surface qualities and develops a model for predicting surface roughness. Results show that ultrasonic vibration significantly improves surface integrity by reducing roughness, refining microstructure, and increasing hardness through cavitation and acoustic streaming mechanisms. Compared with traditional laser polishing (TLP), ultrasonic vibration-assisted laser polishing (UVLP) decreases roughness by 27.2 %, enhances hardness by 23.6 %, and substantially refines the grain structure under specific process parameters. A Back propagation (BP) neural network-based model accurately predicts surface roughness across various processing conditions. This research supports the integration of UVLP for Ti6Al4V, proposing its broader application across other high-performance materials.
