Investigation of temperature resistant lightweight materials used in airplane components with higher thermal efficiency gaining importance. These materials possess challenges and replace twice dense nickel (Ni) based super alloys presently found application in aeroplane industry. In this article, anodic dissolution of commercial gamma titanium aluminide (γ-TiAl) alloys; GE 48-2-2, TNM B1 and TNB V5 were investigated. These are potential materials to be used for manufacturing low pressure turbine blades by electrochemical machining. The materials were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD confirms the presence of two phases Ti3Al, α2 (13.8%) and TiAl, γ (86.2%). SEM shows the porous surface after the anodic dissolution. It has been found that 1 M KBr is the most effective electrolyte for the dissolution followed by NaCl and NaNO3. The effect of temperature, electrolyte concentration, passivation and rotation speed were evaluated. The dissolution potential of TNB V5 found to be high could be due to the presence carbon content which may lead to the high creep resistance in the material.

“…Burger et al [18] have studied the machining parameters influence in terms of the change in MRR and surface roughness in ECM/PECM of nickel-base single-crystal alloy (LEK94). Bahre et al [19] investigated the optimization of the pulse electrochemical machining (PECM) technique by RSM. The process parameters in this work were represented by voltage; pulse on time, frequency, feed rate and pressure and the MRR and surface roughness (Ra) were the responses.…”

The request depending on electrochemical machining (ECM) technique has progressed in a large scale according to different points of view such that; cost or energy consuming, environment protection, reliable performance etc. This work aims to predict and optimize ECM process parameters for important, economic and applicable material (6061 aluminum) by employing L9 Taguchi method as a design of experiment (DOE) approach. This has led to experimental designing, developing a mathematical model and optimizing the entire ECM operation. This was carried out by controlling the chosen process variables (voltage, flow rate speed and electrolyte concentration) in order to optimize and predict the responses namely material removal rate (MRR) and dissolution rate. ANOVA, 3D contour graphs and perturbation plots have been employed to identify the analysis of variance of each response as well as to show the significant model terms. The process parameters i.e. voltage, flow rate speed and electrolyte concentration have been ranged to be 15-25V, 8-12 l/min and 3.36-7 % respectively. In both cases of MRR and dissolution rate the voltage parameter has seen to be the prominent factor that affects the responses so as to investigate highest value of MRR and dissolution rate, 0.477 g/min and 2.149 mm/min, respectively. This has been confirmed due to the results obtained from the ANOVA analysis which shows maximum F-valu for the voltage in the MRR and dissolution rate such that; 921.91 and 1608.34 respectively. But, still there was a considerable enhancement in the MRR and dissolution rate due to the increment in the flow rate speed and electrolyte concentration. Model validation has been carried out and thus the results invistigated that all the considered models were adequate since the residuals in prediction of each response were ignored, because the residuals were semi-matched with the diagonal line. Optimizations of responses were performed in this work numerically by using two types of criteria (restricted and non-restricted). According to these criteria, important increment in the MRR can be obtained which reaches 37%. A considerable enhancement has been obtained in the dissolution rate due to the comparison between the two criteria which results in increment by around 11% as well.
