Tungsten/Chromium Carbide Coatings

 

Our coating formulations have been designed for optimal effectiveness with our thermal spray application process. Our winning CarbideX coating formulations combine tungsten carbide and carefully selected alloys or metals to provide the most economical wear solution available.

Carbide type and volume percentage are critical to the ultimate abrasion resistance of any material used for wear resistance. Cemented carbides are carbides in particle from bonded with a metals; usually Cobalt or Nickel. Hardness varies but all cemented carbides are harder than the hardest metals. 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). The main difference between these coatings is their maximum service temperature limitation. Tungsten carbide has a max temperature rating of 730 F (400C) and chromium carbide 1300F ( 725C). Chromium carbide is indicated where significant corrosion is expected or where high process temperatures are required. (Cleaning ovens require the use of C4000).

C9000 is a unique product that is optimized for fine particle abrasion resistance.  Of the tungsten carbide particles in this material 30% of the mixture is sub-micron sized.  These smaller carbide protect the spaces between the standard 2-5 micron size particles which adds about 25% more wear resistance. C9000 is intended for use in metal injection molding, ceramic molding, and where high loadings of fine particulates accelerate wear.  Call to hear more about the best formulation match for your application!
