Abstract
A coating for a diamond table of a cutting element is described. The coating is employed to fill a plurality of voids left by the manufacturing process that compromise the integrity of the cutting element and the associated downhole tooling. The coating may comprise diamond nanoparticles in a metal matrix and may be used with or without a binder layer applied directly to the diamond table, the coating may alternatively be a pure diamond film coating, and may be employed to fill voids left by the manufacturing process.
