Cr3C2-20NiCr Powder Metco 710/3007 Thermal Spray Powder Metal Production Boiler Coatings Sieves And Cones
CrC80-NiCr20 are spheroidal, agglomerated and sintered powders for thermal spray that contain 80 % chromium carbide as a hard, wear-resistant phase and nickel 20 % chromium matrix that serves several purposes. The NiCr matrix inhibits the decomposition (decarburization) of the chromium carbide during the thermal spray process and functions as a binder for the carbides in service. In addition, the composition of the matrix is responsible for the excellent corrosion and oxidation resistance of these coatings.
