Surface Modification by Electro-discharge Coating and Its Characterisation
Abstract: Applications of coated surface are swiftly increasing in present industrial context. Recently, the electro-discharge route is being explored for surface modification in terms of alloying and layer deposition. Electro-discharge machining parameters and response to surface deposition is of the research interest in electro-discharge coating. In this regard, electro-discharged surface modifications have been characterized in the present investigations. The effect of relevant EDM parameters (current, Pulse duration, duty factor, density of …

Development of EDM Electrode by Powder Metallurgy Process
Abstract: The EDM electrode is specially made of tungsten powder by powder metallurgy process. Negative or reverse polarity is used for better results of layer deposition of electrode material of tungsten powder and carbon particles within the dielectric liquid used for machining. The work piece is of low carbon steel or HSS. It is observed that tungsten carbide layer deposited on the work piece has better performance characteristics for application. In …
