Tungsten CarbideCobaltChromium Powder Discription

Tungsten CarbideCobaltChromium Powder (WC-10Co-4Cr powder) is used for the deposition of wear resistant coatings. Tungsten carbide coatings are sprayed mostly with WC-10Co-4Cr agglomerated and sintered powder. Our HVAF tungsten carbide coatings have excellent resistance to sliding wear, abrasion, cavitation, and erosion. They are tough and reveal good fatigue and impact resistance, excellent corrosion resistance except in high pH environments and in hydrofluoric acid solutions. Our HVAF coatings are gas-tight (non-permeable to gas).

For example, the corrugating roller of a corrugating machine, the rollers are mutually squeezed and driven by tooth-shape matching. With the long-term squeezing and wear between the roller body and the pulp, the tooth-shape changes and the corrugating roller becomes invalid. At this time, the supersonic flame process (HVOF or HVAF) spraying Wc-10Co-4Cr can greatly improve the wear resistance of the corrugated roller surface.

Thermal sprayed coatings of tungsten carbide materials in a cobalt matrix offer the best wear protection. For a service that requires better corrosion resistance, a matrix of nickel, cobalt-chromium, or cobalt-chromium-nickel is a good choice. Materials with a higher percentage of matrix produce coatings with better ductility, resulting in improved impact and fretting resistance. Conversely, a lower percentage of matrix offers greater hardness, resulting in better abrasion and wear resistance.
