COATED GRAPHITE POWDER


graphite

Description:  The product consists in a graphite powder which is coated with a thin layer of nickel. It has been specially designed for reducing the segregation effect that occurs during mixing operations of graphite powders with other metal powders.
Application: The coated graphite powder is added to diamand tool segments in order to create artificial porosities within the sintered matrix. During cutting applications, the sludges wear the matrix and the nickel layer, present at the surface of each graphite grain, erodes. The graphite is then liberated and can play the role of a lubricant.
