WC-Co cemented carbides (hardmetals) represent the backbone materials for the tooling industry. In order to achieve particular tool geometries, diamond wheel grinding is a well-established method for machining hardmetals. ...

The aim of this work was to prepare and characterize polymer–ceramic composite material for dental applications, which must resist fracture and wear under extreme forces. It must also be compatible with the hostile environment ...

In this study the contact fatigue behavior of two coated tool steel is compared. They differ in the chemical nature of the coatings as well as on the deposition route used: a conventional TiN coating prepared by cathodic ...

In this study, the mechanical behavior under monotonic loads of tungsten carbide-cobalt (WC-Co) composites is investigated extensively by analyzing (1) nanoindentation tests on WC particles and Co matrix, (2) nanowires ...

Additive manufacturing of ceramics has attracted large interest due to its unique ability to rapidly prototype, low cost, and increased geometric complexity. Material extrusion technique is often considered for processing ...

In this work, the effect of corrosion-induced damage on the mechanical response of hardmetals was evaluated at small length-scale by means of nanoindentation and nanoscratch techniques. Damage was introduced in a controlled ...

It is well known the interest of the scientific community in substituting the traditional cemented carbides (WC–Co) by alternative ceramic-metal systems. In this regard, Ti(C,N)-based cermets arise as excellent candidates ...

Atom Probe Tomography (APT) was used to obtain a direct evidence of chlor segregation and cobalt diffusion at the grain boundaries (GBs) of polycrystalline coatings deposited by moderate temperature chemical vapor deposition ...

Precision edge preparation techniques for cemented carbides enable optimization of the geometry of tools’ cutting edges. These techniques are frequently used in high-stress environments, resulting in substantial improvements ...
