Laser-assisted jet electrochemical machining (LAJECM) is a hybrid process that combines a relatively low-power laser beam (typically 375 mW) with an electrolyte jet to facilitate metal removal. The main purpose of the laser is to enhance the localization effect of electrochemical dissolution from the workpiece, thus giving better precision and ...
R Thanigaivelanet. al. [10] investigated the effect and parametric optimization of process parameters for electrochemical micromachining (EMM) ofss 304 using grey relational analysis, by using machining voltage, pulse on-time, electrolyte ... It is a kind of effective complexing agent in electrochemical machining of stainless steel. EDTA-Na2
They are commonly made of 316L stainless steel or Nitinol, two alloys containing nickel, an element classified as potentially toxic and carcinogenic by the … Development of an optimized electrochemical process for subsequent coating …
The electrochemical behavior of carburized 316L austenitic stainless steel in this study exhibits the same trend as the 420 martensitic stainless steel of our previous work 7,54 due to the ...
The electrochemical process will not only remove imperfections on the surface after welding – but it will also restore the oxide layer that returns stainless steel back to its normal passive state. Unlike grinding, this cleaning method will successfully remove all dirt and discoloration from the welds.
Stainless passivation is the process by which stainless steel will spontaneously form a chemically inactive surface when exposed to air or other oxygen-containing …
2205 duplex stainless steel (DSS) has good corrosion resistance due to its typical duplex organization, but the increasingly harsh CO2-containing oil and gas environment leads to different degrees ...
Weld cleaning | Wednesday, 14 October 2020 . What is the fastest and safest method to clean stainless steel welds? Electrochemical weld cleaning is a process by which post-weld impurities such as rust, …
Electrochemical surface nitriding of SUS 304 austenitic stainless steel was investigated in a molten system at 773 K, and surface hardening by this molten salt electrochemical process without any special pretreatment was confirmed. From X-ray photoelectron spectroscopy and X-ray diffraction analyses, it was found that the surface …

3.1 Workpiece Selection. The material used as workpiece in our experiment is stainless steel 420. It is selected based on many factors, and one of them is that it is a hard material; despite its advantages, only a very few papers have used this material and they are not electrochemical machining so taking these into account we chose this as …
Cubic samples of 316L stainless steel were displayed in Fig. 1 (b), the scanning strategy was bi-directional scanning with a rotation of 67° for each layer. The as-printed sample has a dimension of 13×13×8 mm. The chemical composition (wt.%) of the LPBFed 316L stainless steel powder is presented in Table 1. The SLM process was …
The electrochemical process will not only remove imperfections on the surface after welding – but it will also restore the oxide layer that returns stainless steel back to its normal passive state. Unlike …
In contrast, the stainless-steel and iron electrode/electrolyte pair showed no activity towards LDPE oxidation or depolymerization. The electrolysis of LDPE offers a new vista for the depolymerization and upcycling of plastics, further understanding of the process is needed.
Fig. 3 is the anode current curve of stainless steel with time, where the applied voltage is 0.15 V. Seen from Fig. 3, the anode current increased rapidly from a low to a high level when laser pulse irradiating, and the anode current quickly fall back to the original level after laser pulse stopping.The higher the laser pulse frequency, the greater …
Baths and Parameters of the Electrochemical Polishing Process of Stainless Steel The electrolyte plays several important roles: • It is the medium in which chemical processes take place;
The entire electrochemical polishing process usually involves the removal of 0.5 – 2 microns of metal depending on the condition of the surface. Electrochemical polishing is used to ensure an ideal combination of aesthetic beauty and very high passivation values. After stainless steel is electropolished, pure chromium covers the metal's ...
