  • Method for producing composite material for coating applications
    Patent number: 8114821
    Abstract: The production of solid lubricant agglomerates by combining solid lubricant powder, an inorganic binder, other fillers if optionally desired, and a liquid to form a mixture, and driving off the liquid to form dry agglomerates which are subsequently classified by size or milled and classified by size to yield agglomerates of a desired size range. These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The undesired size ranges can be readily recycled because the agglomerates with untreated binder can be reprocessed, thereby promoting high recovery rates.
    Type: Grant
    Filed: December 5, 2003
    Date of Patent: February 14, 2012
    Assignee: Zulzer Metco (Canada) Inc.

These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The treated agglomerates are then blended or clad with a metal, metal alloy or a metallic composition, to produce a composition suitable for thermal spray applications.
