electrochemical machining of stainless steel equipment

2020-5-9 · Electrochemical Micro Machining. Abstract: In order to remove the reaction products generated from the interelectrode gap of the electrochemical micro-machining, an angle adjustable electrochemical micro-machining equipment has been developed, which consists of angle adjustment unit, feed system unit, etc. Small holes have been drilled on thin stainless steel 304 by using our developed equipment.

Furthermore, the suitability of Jet-ECM as a finishing process was investigated. Kawanaka et al. investigated the influences of current conditions and nozzle movement speed on surface roughness on stainless steel (SUS304) and realized a mirror-like surface with Rz surface values less than 0.2 µm. They have shown that surface roughness of grooves decreases with the increase of nozzle ...

It is a combination of laser masking and electrochemical etching. In electrochemical etching through laser masking (EELM), selective electrochemical dissolution of stainless steel is achieved in a 2 M sodium nitrite electrolyte. The micro-patterned surface layer of stainless steel is formed by laser marking using an ytterbium pulsed fiber laser.

electrochemical dissolution behaviors. The EELM process enables the electrochemical micro-machining of stainless steel without photolithography technology; thus, it can be applied in micro fabrication, micro patterning and surface texturing. (Some figures in this article …

According to the polarization curve, it can be obtained that oxidation film could be formed in electrochemical machining of stainless steel 304, especially in low current density. In the Section 2 ( Fig.5 ), the numerical simulation indicated that although the voltage was high (30 V), the current density was quite low in conductive mask, and it ...

Precise Electrochemical machining (ECM, PECM) is based on the ability of a metal to dissolve as a result of oxidic reactions occurring in the medium of the electrically conducting solution (electrolyte) under electric current influence. The dissolution process is called electrolysis. Specific features of the electrolysis process are the spatial oxidation (dissolution) of the anode and the ...

2017-11-28 · Abstract—Electrochemical machining is one of the widely used non-traditional machining processes to machine complicated shapes for electrically conducting but difficult-to-machine materials such as superalloys, Ti-alloys, alloy steel, tool steel, stainless steel, etc. Use of optimal ECM

Chemical Machining (CHM) • Chemical Machining (CHM) was developed based on the observation that chemicals attack metals and etch them by using chemical dissolutions. • Chemical machining (CHM) is the controlled chemical dissolution (CD) of the work piece material by contact with a strong reagent.

Precise Electrochemical machining (ECM, PECM) is based on the ability of a metal to dissolve as a result of oxidic reactions occurring in the medium of the electrically conducting solution (electrolyte) under electric current influence. The dissolution process is called electrolysis. Specific features of the electrolysis process are the spatial oxidation (dissolution) of the anode and the ...

When the sulfuric acid-free electrolyte was used to electropolish the 316L stainless steel, the X-ray photoelectron spectroscopy (XPS) analysis shows that atomic Cr/Fe ratio of 316L stainless steel was increased from 0.802 to 1.909 after electropolishing process in the sulfuric acid-free electrolyte of phosphoric acid and glycerol.

Non – Traditional Machining (NTM) or Non – Conventional Machining (NCM), is a kind of machining technology which is different from traditional machining process and equipment. It combines the physical energy (electricity, magnetism, sound, light and heat), chemical energy and even mechanical energy to applied on the machining position ...
