Preparation of Fe‐Pt Powders from Ingot by a Simple and Cost‐Effective Spark Erosion Device
Crystal Research and Technology, 2022 AbstractFePt powders with 1 µm average particle size have been synthesized from bulk ingot with no need for cryogenic temperatures or conventional powder processing. This is achieved with a compact, cost‐effective spark erosion device which is simple to assemble, with no need of a mechanical workshop.

Investigation of Spark Erosion Behavior of Rene 41 Alloy Using Powder Mixed Dielectric Fluid [PDF]
Materials Research, 2021 Abstract The objective of the experimental work is to enhance the machining capability of electrical discharge machining by suspending equal proportion of metal powders such as, molybdenum, nickel, and chromium in EDM 30 oil. Three different control factors such as peak current, pulse on time and powder concentration were varied to analyze the response

Comparative Analysis of Different Graphite Concentrations in Micro-PMEDM Drilling
Journal of Manufacturing and Materials ProcessingMicro-electrical discharge machining is valuable in industry thanks to its ability to realise precise micro-holes with high aspect ratios. However, a limitation of the technology is represented by its low material removal rate compared to other material ...
