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...

The mechanical and tribological properties in WC-Co coatings are strongly affected by hardness and elasticity specifications. The results revealed the effect of spraying distance on microhardness and elasticity modulus of coatings. The metallurgical studies have been made on coated samples using optical microscopy, scanning electron microscopy (SEM). Keywords—HVOF, Micro-indentation, Thermal sp...
