A particle beam deposition apparatus includes a particle source for generating a plurality of particles in suspended form, an expansion chamber, and a deposition chamber connected to the expansion chamber by an aerodynamic focusing stage, and containing a substrate. The aerodynamic focusing stage may be comprised of a plurality of aerodynamic focusing elements, or lenses. Particles, including nanoparticles, may be deposited on the substrate by generating an aerosol cloud of particles, accelerating the particles into the expansion chamber, creating a collimated beam out of the particles by passing them through the aerodynamic focusing lenses and into a deposition chamber, and impacting the particles into the substrate.

Apparatus and method for synthesizing films and coatings by focused particle beam deposition

A method and apparatus for the controlled synthesis and assembly of nanoparticles into nanostructured materials, including nanocomposites, includes a source of nanoparticles and a hypersonic impaction apparatus. The nanoparticles are impacted on a substrate through hypersonic impaction to thereby provide nanostructured materials as well as nanophase materials.

Production of nanostructured materials by hypersonic plasma particle

A method is provided for preparing a diamond coating on a substrate. The method includes a first step of applying a partial diamond coating having an effective amount of void area therein to the work surface of a substrate. In a follow-up step the void area in the partial coating is filled with binder, preferably metallic binder. In a later step, diamond projecting outwardly from the binder is further grown, to generate a covering portion or a head portion extending over, and in protective relationship with, the binder or binder material. According to the present invention preferred products are also provided.
