Abstract
A Pulse Detonation Synthesis (PDS) process for the manufacture and deposition of ceramic powders and coatings is disclosed. PDS may use multiple detonation pulses that are initiated in a reaction chamber to synthesize ceramic materials from reactants introduced into the chamber. The reactants may be provided in the form of divided solids, gases, liquids, gels, and/or mixtures of the foregoing. The synthesized ceramic materials may take the form of micron and/or nano-scale powders or coatings. Non-coating powders may be collected for later use. The coatings produced by the present invention include, but are not limited to, gradient coatings, uniform coatings, thermal barrier coatings, and other commercially useful coatings.

A process for synthesizing a powder material comprising:
- suspending at least one material reactant in a reactant gas inside at least one detonation chamber of a pulse detonation combustor;
- and
- initiating a pulsed supersonic shock wave-triggered detonation combustion wave in said at least one detonation chamber with a fuel source to form a synthesized powder material.
A process for synthesizing inorganic powder materials comprising:
- adding at least one reactant to a reaction chamber of a pulse detonation combustor;
- initiating detonation in said at least one reactant;
- propagating a detonation wave substantially through said at least one reactant;
- and
- said detonation substantially synthesizing the powder material.
A process for synthesizing a powder material, comprising:
- filling a first portion of a combustion chamber with a first mixture capable of detonation;
- filling a second portion of said combustion chamber with a second mixture capable of detonation;
- activating an ignition means to initiate detonation;
- initiating detonation within said first mixture;
- propagating a detonation wave through said first mixture and into said second mixture;
- initiating detonation in said second mixture;
- modifying said second mixture in said second portion of said combustion chamber to synthesize the powder material;
- and
- exhausting the synthesized powder material from said combustion chamber.
