Mapping Between Nonlinear Kinetic Characteristics of TiAl Alloy Electrolytic Machining Systems and Machined Surface Morphology
s:The magnitude and fluctuation pattern of the current density has been an important parameter of the electrolytic machining process,but the mapping relationship between its fluctuation pattern and the microscopic morphology of the elec-trolytically machined surface has not received much attention.Nonlinear kinetic behavior of current density during electrolytic machining of TiAl alloys using phase space reconstruction,recurrence plot and recurrence quantification analysis.And the micro-morphology of the machined surface is quantitatively characterized using roughness and lacunarity.It was determined that both electrolyte pressure and pulse frequency were pivotal factors influencing the nonlinear kinetic behavior of the elec-trolytic machining process and the micromorphology of the machined surface.At an electrolyte pressure of 0.35 MPa or a pulse frequency of 300 Hz,the structure of the TiAl alloy electrolytic machining system is optimized for simplicity and stability.This configuration also yields the smoothest and most homogeneous machined surface,demonstrating a favorable alignment between the structural characteristics and the electrolytic machining system and the micro morphology of the machined surface.
