Micro EDM with the in situ electrochemical fabrication and regeneration of the tungsten microelectrode tool

Abstract Interface interaction between gallium-based liquid metal and copper-based materials results in the formation of intermetallic CuGa2 grains. In particular, CuGa2 grains are able to produce a uniform film and the newly formed CuGa2 film holds peculiar characteristics, which have not been fully explored up to now. In this study, we present an electrochemical fabrication method of an in situ CuGa2 film on copper surface. Surface morphology and chemical composition of this film are confirmed. Tribological experiments demonstrate that the CuGa2 film enables good antifriction and antiwear abilities. Furthermore, the lubrication mechanisms of the CuGa2 film are revealed.

AbstractHerein, a simplified fabrication method for the producing of a pH-sensitive iridium electrode is developed. The in situ electrochemical fabrication of an iridium oxide film is optimized and shown to be achievable under neutral conditions rather than the acidic conditions hitherto employed. The formation of a pH sensitive Ir(III/IV) hydrous film is confirmed via XPS. The amperometric pH-sensing properties of this electrochemically generated material were investigated using square wave voltammetry. In the pH range 2–13, the iridium oxide redox signal has a pH dependency of 86.1 ± 1.1 mV per pH unit for midpoint potentials with uncertainties being ± 0.01–0.05 pH. Finally, the newly developed pH sensor was used to measure the pH of a natural water sample with excellent results as compared to a conventional glass pH probe.
