Cr3C2 37WC 18Metal Alloy Powder Description:
Cr3C2 37WC 18Metal Alloy Powder is a spheroidal, agglomerated, and sintered powder designed for thermal spray applications. Comprising a uniform distribution of 43% chromium carbide, 37% tungsten carbide, and 18% metal alloy binder, this powder features medium-sized carbide grains as hard phases. HVOF coatings made from this material are dense and exhibit excellent bond strength, outperforming coatings applied using atmospheric plasma spray or combustion powder Thermospray techniques. The coatings offer superior hardness, abrasion resistance, and cavitation resistance, with corrosion resistance in harsh environments that is comparable to or better than WC 10Co 4Cr or Cr3C2 20(Ni 20Cr) coatings. Ideal for protecting pumps and boilers and as an alternative to hard chromium plating, these coatings can be used at service temperatures up to 700°C (1290°F). The fine particle size distribution of the powder results in tough, dense coatings that often do not require post-coat finishing.
