To fully understand the electrochemical machining profile, a multi-physics coupling simulation model including flow-electric-temperature-structure field were established to analyze corrosion process of anode material and change trend temperature,hydrogen volume fraction, electrolyte conductivity current density in processing gap.The analysis results show that temperature hydrogen content gradua...

Abstract GH4169 super alloy has a wide application in the field of aeronautics and astronautics, order to realize high quality fast processing complex workpieces with electrochemical machining (ECM), we have studied dissolution characteristics composite electrolyte, explored rule influence on voltage, feed speed, electrolyte pressure for gap (SG), material removal rate (MRR) surface roughness (...

correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

Electrochemical machining is widely used in biomedical, aerospace, automotive, and other fields. The development of electrochemical (ECM) restricted by many factors such as the difficulty preparing micro-electrode, large machined gap serious stray corrosion. In this paper, we present a method to fabricate micro-holes combining micro-graphite electrode with hollow structure. Firstly, sealed grap...

This paper studied the rule of micro-hole in electrochemical jet machining (EJM) TC4 alloy and established mathematical model process predicted profile. Considering influence gap time, orthogonal experiment was designed. based on response surface analysis (RSA) method. The results indicate that can improve directivity machining, reducing efficiency, but will cause secondary corrosion abrupt cha...

Diamond is a material of interest due to its unique combination of properties, including its chemical inertness and biocompatibility. Polycrystalline diamond (poly-C) has been used in experimental biosensors that utilize electrochemical methods and antigen-antibody binding for the detection of biological molecules. Boron-doped poly-C electrodes have been found to be very advantageous for electr...
