Tungsten Carbide Grades – Extramet Products

Tungsten carbide is a homogenous mixture of tungsten carbide grains in a tough cobalt binder matrix. The carbide grains are fused into a solid matrix of cobalt metals. The metal carbide’s grains are “cemented” in the binder metal’s matrix. The fusion process is called liquid phase sintering, or …

The Lexicon: Explains specific terms -

The liquid phase will wet the tungsten carbide particles completely, and will penetrate between the agglomerated hard material particles. For this process to occur, it is important that the binder metal can sufficiently wet the hard material particles. Surface tension will cause the tungsten carbide particles to flow together, which results in ...

Modes of Failure of Carbide Wear Parts by Federal Carbide

Modes of Failure of Carbide Wear Parts. Carbide wear parts fail in a number of different ways. Unfortunately, there is no “one best” grade of carbide for all applications and replacing one grade with another may decrease the probability of one type of failure from occurring, but generally increases the odds that a different one will occur.

Tungsten Carbide - an overview | ScienceDirect Topics

5.3 Tungsten Carbide. Tungsten monocarbide is the most important commercial tungsten carbide. It forms the basis for the whole cemented carbide industry, which produces a large array of dies, cutting tools, drills, etc. Cemented carbides are composites of the hard grain or powder bonded by a metal phase, typically cobalt.

Study on the Friction and Wear Characteristics of Tungsten ...

It is therefore necessary to characterize the friction and wear properties of the hard materials, tungsten carbide (WC) and zirconium (Zr), with the high-viscosity liquid-containing nitride or yttrium aluminum garnet (YAG) particles under reciprocating conditions. Particle contents of 15 wt.% and 30 wt.% are added to the liquid.

HVOF Tungsten Carbide Coating Properties, Structure and ...

WC-12Co thermal spray coatings are usually harder compared to coatings of WC-17Co as a result of higher tungsten carbide levels in the coating. The tungsten carbide WC-12Co coatings are resistant to sliding wear, impact, abrasion and fretting at temperatures up to …

Wettability of tungsten carbide by liquid binders in WC–Co ...

The wettability of tungsten carbide by liquid binders with various carbon contents and infiltration of WC–WC grain boundaries in cemented carbide by such binders were examined. The wettability of tungsten carbide by the liquid Co-based binder is complete at low carbon contents and becomes incomplete when increasing the carbon content.

Tungsten carbide - Wikipedia

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments ...

How to Recycle Tungsten Carbide -

Tungsten carbide (WC) is chemically a binary compound of tungsten and carbon in the stoichiometric ratio of 93.87% tungsten and 6.13% carbon. However, industrially the term usually implies cemented tungsten carbides (CWC); a sintered powdered metallurgical product consisting of very fine grains of pure tungsten carbide bound or cemented together in a cobalt matrix.
