Electropolishing of pure metallic titanium in a deep eutectic solvent ...
2021年1月1日 · This work presents a facile and efficient electropolishing of metallic titanium (Ti) in the relatively eco-friendly electrolyte of deep eutectic solvent (DES) using a mixture of choline chloride-propylene glycol (1 mol ChCl: 2 mol PG).
Compared to the other polishing processes, electropolishing is an effective method to clean, smoothen and polish, the titanium surface. It removes impurities from the metal surface and gives the surface a high luster. The present work was carried out to identify effective process parameters for electropolshing titanium. Different
A new perchlorate-free electrolyte electropolishing proc-ess for titanium and titanium alloys has been developed, using a sulfuric acid-methanol mixture as electrolyte. Electrolyte composition and polishing conditions were optimized by measuring current-voltage curves on a ro-tating disk electrode at temperatures of -10 to 25 °C.
The Electropolishing of Additively Manufactured Parts in Titanium …
2021年9月6日 · The electropolishing (EP) treatment could be ideal for simple, complex, or porous parts characterized by low surface quality. Herein, it is aimed to provide the state of the EP treatment's art carried out, to date, on additively manufactured …
Development of an Electropolishing Method for Titanium Materials Alexandre Faria Teixeira The objective of this research is to develop a new electropolishing (EP) method for titanium (Ti) materials, which will enable a significant roughness reduction of complex parts manufactured by selective laser sintering (SLS).
Fundamental aspects and recent developments in electropolishing ...
2019年4月1日 · Titanium sheets were electropolished in an ethylene glycol-NaCl electrolyte solution with an addition of various concentrations of ethanol as an additive [45]. Fig. 16 shows the electropolished Ti results with 0% and 20% ethanol additive.
Electrochemical Polishing of Ti and Ti6Al4V Alloy in Non-Aqueous ...
2024年6月10日 · The latest findings reveal that electropolishing titanium in methanol–sulfuric acid electrolytes is controlled by mass transport. Variations in the current density suggest that transferring dissolved tetravalent titanium species from the anode surface limits the rate.
Parameters Optimization for Electropolishing Titanium by Using …
2023年2月14日 · Karim et al. reported a simple, rapid and efficient of titanium electropolishing by utilizing an environmentally friendly choline chloride-based ionic liquid, known as Ethaline. Under machining condition of 6–10 V in 30 min of machining time, a potential electropolishing process was performed without the obvious presence of gas evolution.
The electropolishing of titanium and its alloys - ScienceDirect
2004年6月1日 · In a quite dif- ferent field, titanium is widely used for surgical and medical implants, both skeletal and dental. Here too, the state of the surface finish is critical, and numerous studies have shown the benefits of elec- tropolishing. Last but not least, blades of gas tur- bine engines are routinely electropolished.
Electropolishing of Additively Manufactured Ti‐6Al‐4V Surfaces in ...
2022年5月20日 · This paper reports the electropolishing of additively manufactured Ti-6Al-4V by powder bed selective laser melting (SLM) using a nontoxic electrolyte solution. The results have shown that the salt-based electrolyte can be used to electropolish titanium alloys.
