Two different grades, WC-20 vol.% Ni and Co cemented carbides, respectively were systematically investigated concerning their microstructure, binder composition, corrosion behavior. SEM-EBSD analysis verified that both grades have similar WC grain sizes (0.9–1.1 μm). AES confirmed the phase of respective grade is an alloy Ni-W Co-W concentration W in Ni- Co-binder 21 10 at. %, respectively. In ...

Cemented carbides are used in the cutting tools industry thanks to their exceptional mechanical properties. Manufactured by powder metallurgy route, they made of a hard WC phase with ductile metallic binder, most commonly Co. Due lower availability Co and its classification as carcenogenic material REACH European Regulation, new binders have be considered: Fe Ni investigated this work. Because ...

Abstract A great deal of attention has been paid to friction and wear caused by current-carrying friction. In this study, diamond coatings were deposited on the cemented carbides (WC-Co) substrate hot filament chemical vapor deposition method. Although coating possessed a higher roughness than WC-Co substrate, it was effective at reducing coefficient improving effectiveness in process. presence...

Abstract. The main objective of the present work was to determine influence laser beam processing (LBP) on microstructure, microhardness, roughness, and corrosion resistance coatings produced C45 carbon steel by electro-spark deposition (ESD) process. studies were conducted using WC-Co electrodes Pulse Plasma Sintering method (PPS) nanostructural powders. deposited means EIL-8A they treated wit...

This study investigates the effect of carbide particle size on the microstructure, mechanical properties, and abrasive wear resistance of WC-17%Co HVOF-sprayed coatings. The characteristics of WC-1, WC-2, and WC-3 coatings with carbide sizes of 1 µm, 0.9 µm, and 0.5 µm, respectively, were also investigated. WC-1 coating experienced the maximum carbon loss of 42%, while WC-2 and WC-3 coatings un...
