Ni 25C Graphite Powder Description:
Ni 25C Graphite Powder, crafted through the hydrometallurgy autoclave process, combines nickel encapsulation of graphite to ensure uniform distribution and continuous cladding. This method minimizes segregation, enhances sprayability, and leverages graphite as a solid lubricant to enhance abradability in coatings. These characteristics are vital for optimizing clearance control in applications where coatings intermittently engage rotating components.
