Ni 20Al Powder Description:
Ni 20Al Powder is a high-performance material featuring a fine, spheroidal structure with an aluminum core encapsulated in a nickel shell. Manufactured through the hydrometallurgy process, this powder exhibits consistent chemistry and uniform nickel shell thickness. It is renowned for its excellent oxidation and thermal shock resistance, making it particularly suitable for turbine applications. The powder forms self-bonding coatings on a variety of metallic substrates with minimal surface preparation, thanks to its unique ability to chemically unite during the spray process to form nickel-aluminides. These intermetallic compounds enhance the heat resistance of the coatings. Ni 20Al Powder can be applied using either atmospheric plasma or combustion powder spray processes, with atmospheric plasma spray offering superior oxidation resistance and higher density.
