Hastelloy is a metal material with high strength and excellent corrosion resistance, widely used in aerospace, energy, and automotive industries. However, the surface roughness of Hastelloy often requires further treatment to meet specific application requirements.
Electropolishing (EP) is a chemical reaction-based process that removes surface asperities, effectively improving surface smoothness and reducing roughness. However, during the EP process, significant material removal may occur, posing risks of excessive thinning for thin-walled structures. In contrast, Electrostatic Induction Electrochemical Machining (EIECM) is an innovative technique that utilizes electrostatic fields to optimize electrochemical reactions, achieving uniform material removal with lower material loss. Both methods enhance the surface quality of Hastelloy effectively while avoiding the high mechanical stress and thermal effects associated with conventional processing methods, making them suitable for applications requiring high precision and surface quality. This study aims to explore the differences, advantages, and disadvantages of these two electrochemical processing methods, providing effective solutions for precision machining.
This research investigates the application characteristics of EIECM in polishing the inner walls of Hastelloy tubes. Compared to EP, EIECM can effectively control material removal, achieve inner wall polishing, and reduce material loss. The study focuses on processing parameters such as voltage, processing time, electrolyte flow rate, and electrolyte temperature, analyzing their effects on surface roughness, material removal rate, roughness uniformity, and passivation layer thickness. Experimental evaluations under various conditions reveal that both EIECM and EP significantly improve the surface quality of inner tube walls, effectively reducing surface roughness. However, EIECM demonstrates superior material retention properties compared to EP. This method shows higher processing uniformity and cost-effectiveness in thin-walled structure machining, making it well-suited for polishing the inner walls of high-performance alloy materials. |
