Ni 40C Graphite Powder Description:
Ni 40C Graphite Powder is a specialized composite powder where graphite is encapsulated in nickel, created through the hydrometallurgy autoclave process. This distinctive production technique ensures uniform distribution and continuous cladding of graphite within a nickel shell, reducing segregation and improving sprayability. In coatings, graphite serves as a solid lubricant, enhancing abradability with controlled porosity levels, which is essential for optimizing clearance control in applications where rotating components may intermittently contact the coating.
