In this work, the electrode wear rate (EWR) and electrode surface characteristic of copper electrode when EDM of Nickel Based Super Alloy, Inconel 718 at higher peak current and pulse duration were analyzed. Experiments were conducted using Inconel 718 as a work piece and copper as an electrode with a kerosene dielectric under different peak currents and pulse durations. Peak current, Ip within a range of 20A to 40A and pulse duration (or pulse on-time), ton within a range of 200μs to 400μs are selected as the main parameters. In this study, EWR were measured using digital weight balance (accuracy 0.01mg) and by using Scanning Electron Microscope (SEM), the surface texture of the electrode in order to evaluate the material deposited on the electrode surface. The results have shown that machining at a lowest peak current of 20A and highest pulse duration of 400μs yields the lowest electrode wear rate (EWR) of -0.01mm3/min. The pulse duration is significantly affecting the EWR. It also revealed that, the deposited of carbon and work piece material is occurred on the electrode surface for all machining conditions.

Cell Construction

A Raman spectroelectrochemical cell has been developed which incorporates a rotating disk design. This cell has been shown to be useful for the Raman investigation of electrode surface species (spinning electrode) and electrogenerated solution species (static electrode). It has been used to characterize the Raman spectroelectrochemical behavior of photolabile dithizone anion adsorbed at silver and copper electrode surfaces. Use of this cell for the study of electrogenerated solution species was demonstrated by the resonance Raman characterization of the tetracyanoethylene anion radical electrogenerated with a cyclic potential step. Cell construction is described and its merits discussed.
