Patent ID: 7758784

Claim:
A method, comprising the steps of: a) placing a volume of first particles into a mill, the first particles ranging in size from 1 nanometer to 100 nanometers; b) placing a volume of second particles into said mill, the second particles ranging in size from 1 micron to 200 microns; c) operating said mill at a temperature to mix said first particles and said second particles such that the first particles are distributed generally uniformly among said second particles so that said second particles become substantially coated with said first particles while breaking up the agglomeration of said first particles; d) performing said placing steps a) and b) and said operating step c) to create at least one surface layer coating of said first particles onto said second particles without any substantial mechanical alloying or chemical reaction taking place between the first particles and second particles; wherein said volume of said first particles used in said placing step a) is proportional to a surface area of said second particles in said volume of said second particles; and e) compacting and sintering said first and second particles to produce a part.
