A novel method for fabricating an adhesive resistance surface is presented. Sandblasting and electrochemical machining were introduced to prepare micro-nano structures on the sample surface. Then, the prepared sample was immersed in a tridecafluoroctyltriethoxysilane ethanol solvent. The surface of the aluminum alloy sample roughened and covered with low-surface-energy chemical groups was exami...

The optimal design of Electro Chemical Machining (ECM) processes is of significant technological importance. In the present work ECM processes with an oscillating tool electrode are considered. It is motivated by the fact that the workpiece electrode may suffer damage or may even fail if the applied load due to hydrodynamic forces is too large. A simple formula is developed for the reaction for...

ECM emerges out to be one of the major non conventional machining techniques based on Faraday‟s laws of electrolysis, highly efficient due to its zero tool wear characteristic. Occurrence of passivation is the major problem faced in ECM. In the present work, study of the flow pattern of electrolyte has been performed so that, the machining variable distribution can be predicted accurately thus ...

The solution to free boundary problems arising from electrochemical machining processes is considered. A mathematical description of the machining process is presented with particular consideration given to its electrochemical properties and to the appropriateness of its treatment as a potential problem with Dirichlet boundary conditions. A number of different machining configurations are consi...

Electric discharge machining (EDM) is a type of high-precision usually applied to hard-material for mold manufacturing and in the aerospace industry. Longer process times typically reduce facility efficiency. The use electrochemistry (ECM) can overcome this challenge efficiently machine large workpieces. Some industries have adopted combined these two processes Inconel 718 material machining. H...

In this paper, a thorough review has been presented on the latest research work carried out for the enhancement of machining performance of one of the most commonly used superalloys that is, Inconel 718. The thermal energy has been frequently utilized for improving machinability characteristics of Inconel 718. The review of available literature indicates that plasma, laser, and electric dischar...
