Abstract:
1. A method comprising: combining a nano-sized powder of one material with micron-sized particles of another material, said micron-sized particles comprising titanium or its alloys and said nano-sized powder comprising particles having a size of between 1 and 80 nanometers; ball-milling the powders to produce a mixture in which a number of nano-sized particles in any volume is substantially proportional to a surface area of said micron-sized particles in the volume; and performing said ball-milling step to de-agglomerate said nano-sized particles and cause said nano-sized particles to be generally uniformly dispersed among said micron-sized particles and said nano-sized particles become embedded and bound to a surface of each of the micron-sized particles to provide a coating into or onto each of said surfaces of said micron-sized particles, said nano-sized particles coating said surface of each of said micron-sized particles to provide a hybrid particle with a total number of hybrid particles being less than a total sum of the nano-sized particles and micron-sized particles, with said hybrid particles each being larger than said micron-sized particles; wherein said ball milling produces said coating of said nano-sized particles into or onto each of said surfaces of said micron-sized particles, with a number of nano-sized particles in any volume being substantially proportional to a surface area of micron-sized particles in said volume for a single layer coating; each of said hybrid particles being defined by one of said micron-sized particles that has at least one coating of said nano-sized particles on its surface so that at least one layer of said nano-sized particles is spread over of the surface of said micron-sized particles.
