TUNGSTEN CARBIDE COATING

Tungsten Carbide Coating

Tungsten Carbide Coating

There are several methods used to totally encapsulate a screw with wear and/or corrosion-resistant material. The methods include detonation guns, high velocity oxygen fuel (HVOF) spray systems and various spray weld processes. A wide selection of materials can be used ranging from the types of materials used for flight hard-surfacing to customized products containing very hard wear resistant carbides.

Descriptions
XC1000
Rc68/71
A composition of 12% Cobalt saturated with 88% 2-5 micron Tungsten Carbide with a particulate hardnss average of Rc82, providing ultimate abrasion resistance.
XC1000Ni
 
Rc68/71
A composition 10% Nickel and 90% Tungsten Carbide providing ultimate abrasion resistance combined with improved corrosion resistance over the XC1000 in PVC applications.
XC4000
Rc55-65
A composition of Nickel, Chromium, and Chromium Carbide producing an abrasion resistant coating with extreme corrosion resistance and excellent ductility, relative to hardness.
XC9000
Rc65-70
Our Millennium Carbide is a Tungsten Carbide/ Cobalt featuring a unique sub-micron manufacturing process providing improved wear resistance over traditional Tungsten Carbide coatings. Excellent for sub-micron particle abrasion.

High competence in heat treatment technology and surface coating assure a superior wear protection. The most advanced and modern equipment in the hands of experienced specialists allows the production of the most complex design as wave geometry on plasticizing screws.


Benefits:
