Optimizing and understanding dry-electropolishing process on WC-Co cemented carbide material

International Journal of Refractory Metals and Hard Materials
Dry-electropolishing (DEP) combines an electrochemical process with soft-mechanical abrasion by using porous ion-exchange particles (also known as dry-electrolyte). In recent years, it has been satisfactorily implemented for reducing surfaces defects, decreasing roughness, and obtaining smooth surface finish in several metallic and ceramic-metal ...

Stripping process of TiAlN/TiSiN coating on WC-Co cemented carbide substrate by using the dry-electropolishing technique

Surface and Coatings Technology
Physical Vapor Deposition hard protective coatings are frequently applied to hardmetal cutting tools to extend their lifespan under service-like working conditions. However, these coatings may experience damage during their performance, such as wear. In addition, defective coatings during the production process can occur, requiring reconditioning.

Investigating post-processing impact on fatigue performance of LPBF Ti6Al4V with heat treatment, high pressure heat treatment, and dry electropolishing strategies

International Journal of Fatigue
This study investigates the impact of post-processing techniques on the fatigue behaviour of specimens in Ti6Al4V made by laser powder bed fusion (LPBF) for relevant applications, such as motorsport. Despite the LPBF advantages in terms of complex design and weight reduction, challenges such as reduced fatigue performance persist.

Effect of surface roughness on strain distribution during bending

IOP Conference Series: Materials Science and Engineering, 2022
The limited formability of ultra-high strength steels (UHSS) poses some challenges for the bending process in the form of strain localisation, surface defects and pseudo-polygonal “nut-like” shape of the bend.
