This study investigated and compared the acid-free electropolishing of copper with state-of-the-art acidic process. The medium used in this is based on a deep eutectic solvent comprised 2:1 ethylene glycol choline chloride. electrochemical included voltammetry chronoamperometry tests during characterization techniques were atomic force microscopy (AFM) digital microscopy, surface morphology com...

TB2 titanium alloys are widely used in the aerospace industry. A high surface quality is required for performance and fatigue life of alloy parts. Electropolishing useful thin metal plates owing to its good processability conformability. In this study, electrolyte flushing was proposed electropolishing a large NaCl-containing ethylene glycol adopted. Three different mechanical grindings were em...

Electropolishing at high current densities without agitation of the electrolyte results in a pitting phenomenon that produces dimple-like surface features. Although is unfavorable electropolishing process, its effect on modification, such as texturing, has not been thoroughly investigated. Surface topography and chemical composition analyses electropolished steel revealed pits an oxide layer, i...

Electropolishing of metal surfaces is a benign alternative to mechanical treatment. Ionic liquids are considered as green electrolytes for the electropolishing metals. They demonstrate number advantages in comparison with acid aqueous solutions and other methods producing smooth or mirror-like that required by diverse applications (medical instruments, special equipment, implants prostheses, et...

Abstract The present work aims at studying the damping response of a NiTi auxetic structure fabricated through additive manufacturing. Furthermore, an electropolishing route has been accounted for improving roughness on external surface printed samples. capacity manufactured components is evaluated amount energy dissipated per cycle and loss factor index. Results show that cell takes advantage ...

The focus of this project was to design and construct a model controlled-flow apparatus to study electropolishing of one cm 2 niobium coupons at surface flow rates typical of cavity processing. A simulation of the apparatus was constructed using CFDesign, a flow and thermal simulation software, to ensure that the selected dimensions may be expected to provide steady-state, laminar flow across t...
