Cr3C2-25NiCr Powder Thermal Spray Powder Metco 720/730 Piston Rods Chemical Processing Tooling
CrC75-NiCr25 are spheroidal, agglomerated and sintered powders for thermal spray that contain 75 % chromium carbide as a hard, wear-resistant phase that has a minimal tendency for decomposition during the thermal spray process. A nickel-chromium (80 % / 20 %) matrix functions as a binder for the carbides, and is also responsible for the excellent corrosion and oxidation resistance of these coatings.
