Ni 20Al Powder Description:
Ni 20Al powder is a high-performance material with a fine spherical structure with an aluminum core encapsulated in a nickel shell. Manufactured by a hydrometallurgical process, this powder has consistent chemistry and uniform nickel shell thickness. It is known for its excellent resistance to oxidation and thermal shock, making it particularly suitable for turbine applications. Due to its unique ability to chemically bond to form nickel aluminide during the spray process, the powder can form self-bonding coatings on a variety of metal substrates with minimal surface treatment. These intermetallic compounds improve the heat resistance of the coating. Ni 20Al powders can be sprayed using atmospheric plasma or combustion powder spraying processes, which have excellent oxidation resistance and higher density.
