WC-based hardmetals are employed widely as wear-resistant ceramic–metal composites for
tools and wear parts. Raw materials supply, environmental concerns and some limitations of …

Thermal spray WC-based coatings are widely used in the aircraft industry mainly for their
resistance to wear, reworking and rebuilding operations and repair of worn components on …

The WC grain growth behaviour and mechanical properties of coarse-grained cemented
carbides with bimodal grain size distributions were investigated using WC-5Co composite …

Generally, well wear resistance corresponds to low friction coefficient. While, well wear
resistance and high friction coefficient are needed in brakes for short braking distance and …

Abstract WC-(nanoWC-Co) with micro-WC reinforcing particles in nanoWC-Co cermet matrix
was cold-sprayed by using WC-Co with bimodal sized WC particles (with both micro-sized …

Development of nanostructured hardmetals is a task of great importance. Nevertheless, in
spite of some “euphoria” with respect to nanograined hardmetals, their potential application …

In the present work we made and examined cemented carbides characterized by very
different WC grain sizes varying from near-nano with a WC mean grain size of about 200 nm …

Abstract Design of the drill–bit and selection of the Cemented Tungsten Carbide (CC) grade
for drill–bit inserts are crucial for efficient percussive drilling. This study presents the results …

Cemented carbides, containing hard WC grains in a ductile Co binder, are commonly used
as the rock crushing part of rock drills. They generally work well and show moderate and …

Drill bits equipped with WC-Co cemented carbide buttons offer great performance in many
rock drilling applications. Generally, the wear of these buttons against the rock is gradual …
