About Us. Provide customers with superb products and services.
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 with a Vickers number of 1700-2400 (85 HRC equivalent) is composed of 90% carbide particles by weight, 80% by volume. Most standard wear resistant alloys contain a maximum of 35% by volume of softer chromium carbide. We offer coating formulation options, mainly tungsten carbide (C1000, C1000Ni, C9000) and chromium carbide (C4000).
A tungsten carbide surface is finished to an RMS surface roughness of about 25 nm (1.0 microinch) or less by abrasion using diamond grit particles. The tungsten carbide surface is abraded by a sequence of grit particle-containing abrasive members, such as abrasive films, pastes, or slurries, at least one of the members having an average grit particle diameter of about 2 μm or less.

Carbinite is a tungsten/carbide or stellite/carbide alloy that can be applied to most metals using a process called Electro Spark Deposition (ESD), yielding a true metallurgical bond. This high bond strength far surpasses any spray-on coating currently available.
Common Tungsten Carbide Defects. From the book Building Superior Brazed Tools Buy the Book. Internal. The most common and most serious problems in Carbide are internal. Left is a well made tip that suffered impact and had only minor chipping in one corner. Right is tip that was poorly made and failed along a fault line.

Our Patent 5,624,626, Apr. 29, 1997 – a purely electrical method of improving surface wettability. The ECP treatment takes advantage of the difference in electrical resistivity of tungsten carbide grains and the cobalt binder. It selectively removes the cobalt and leaves exposed tungsten carbide grains.
Oct 07, 2014· Tungsten Carbide (WC) Thin Films. Thin films of tungsten carbide have wide technological applications as wear resistant and protective coatings on a variety of surfaces such as cemented carbide tools, steel, copper, and copper alloys. For normal steel, copper, and copper alloys, a coating of WC–Co has been found to be suitable.
The wetting behavior of copper on tungsten carbide surfaces was investigated through the sessile drop method, at 1080 °C, in vacuum atmosphere.
Rough to smooth-as-sprayed surfaces can offer grip and a possible increase of friction coefficient (based on mating material hardness) with the long wearing carbide surface. Tungsten Carbide and Chrome Carbide are the predominant carbide materials used to apply protective surfacing using Thermal Spray processing. Relatively thin layers can ...
Vitrified bond diamond grinding wheel improves the surface quality of the workpiece because of its good shape retention.At present, cemented carbide tools are widely used, and the type of tungsten and titanium carbide is increasing, and their quality is constantly improving.
Waste tungsten carbide can generally be reused by APT (ammonium paratungstate) process, zinc recovery process or by pulverization. These "recycled" tungsten carbide powders generally have better, predictable densification because their surface area is smaller than tungsten carbide powder made directly from the tungsten carburizing process.
Some of our competitors sell Tungsten rings that do not include Carbide. (Some of the retailers still call them Tungsten Carbide however, so be careful.) A Tungsten only ring is basically a steel ring. It is very hard, but NOT scratch proof. A Tungsten Carbide ring can only be scratched by a diamond or a product containing the mineral corundum.
Tungsten carbide is a chemical carbide containing equal parts of tungsten and carbon atoms. It is approximately twice as strong as steel with double the density and is double the density of steel—nearly midway between that of lead and gold.
Tungsten carbide coating and sprays have increasingly become the most preferred method for improving or salvaging components. Thermal spraying is a process of coating that involves spraying melted materials onto the surface of another component with the aim of coating it.
…used in the form of tungsten carbide for very hard and tough dies, tools, gauges, and bits. Much tungsten goes into the production of tungsten steels, and some has been used in the aerospace industry to fabricate rocket-engine nozzle throats and leading-edge reentry surfaces.
