OBRABOTKAMETALLOV Vol. 27 No. 2 2025 technology Fig. 15. Three-dimensional images of surfaces after various treatments are removed. The combination of CET+CT significantly speeds up the treatment process by removing the strong oxide film and intensifying chemical etching due to high temperatures. When clusters collapse during the CAT process, the resulting shock waves are transferred to abrasive particles that strike the surface, exerting a micro-cutting effect. In addition, the particles, when interacting Fig. 16. Schematic illustration of surface change dynamics during various types of ultrasonic treatment
