Abstract

In one embodiment, a method includes depositing a material on a substrate. The material includes: a plurality of particles configured to complete a self-propagating and/or self-sustaining reaction upon initiation thereof, a solvent system, and one or more stabilizing agents.

First claim

What is claimed is:

1 . A method, comprising:
depositing a material on a substrate, the material comprising:
a plurality of particles configured to complete a self-propagating and/or self-sustaining reaction upon initiation thereof;
a solvent system; and
one or more stabilizing agents.

2 . The method as recited in claim 1 , wherein the self-propagating and/or self-sustaining reaction renders at least surface(s) of the substrate onto which the material is deposited conductive.

3 . The method as recited in claim 1 , wherein the self-propagating and/or self-sustaining reaction comprises a thermite and/or an intermetallic reaction.

4 . The method as recited in claim 1 , further comprising initiating the self-propagating and/or self-sustaining reaction.

5 . The method as recited in claim 1 , wherein the material is deposited as a first layer of the material, the method further comprising: depositing one or more additional layers of the material onto the first layer of the material.

6 . The method as recited in claim 5 , further comprising initiating the self-propagating and/or self-sustaining reaction, wherein the self-propagating and/or self-sustaining reaction fuses two or more of: the first layer of the material, and one or more of the additional layers of the material.

7 . The method as recited in claim 5 , further comprising initiating the self-propagating and/or self-sustaining reaction in each layer of the material subsequent to depositing the first layer of the material, and prior to depositing a subsequent one of the additional layers of the material.

8 . The method as recited in claim 1 , further comprising depositing one or more additional layers of the material and one or more layers of a second material to form a structure comprising alternating layers of the material and the second material; and
wherein the layers of the second material comprise a non-energetic material.

9 . The method as recited in claim 8 , further comprising initiating the self-propagating and/or self-sustaining reaction in each layer of the material;
wherein each self-propagating and/or self-sustaining reaction generates heat, and wherein the heat generated by each self-propagating and/or self-sustaining reaction at least partially melts at least one adjacent layer comprising the second material.

10 . The method as recited in claim 1 , further comprising initiating the self-propagating and/or self-sustaining reaction in an aqueous environment.

11 . The method as recited in claim 1 , further comprising initiating the self-propagating and/or self-sustaining reaction in vacuum.

12 . The method as recited in claim 1 , further comprising initiating the self-propagating and/or self-sustaining reaction, wherein the self-propagating and/or self-sustaining reaction performs thermal work and/or chemical work on the substrate upon initiation thereof.

13 . The method as recited in claim 1 , wherein the material is deposited onto the substrate according to a predetermined pattern spatially configured to produce a desired configuration and/or a desired structure in the substrate upon completion of the self-propagating and/or self-sustaining reaction.

14 . The method as recited in claim 1 , wherein the material is deposited onto the substrate according to a predetermined pattern spatially configured to produce a desired symbol on one or more surfaces of the substrate upon completion of the self-propagating and/or self-sustaining reaction.

15 . The method as recited in claim 1 , comprising:
scanning the substrate during deposition of the material; and adjusting the deposition in response to detecting one or more deviations from an intended structural arrangement.

16 . The method as recited in claim 1 , wherein the material comprises one or more precursor materials for forming a ceramic via the self-propagating and/or self-sustaining reaction.

17 . The method as recited in claim 16 , wherein the ceramic is characterized by either:
resistance to one or more types of radiation; and/or being a thermal insulator.

18 . The method as recited in claim 1 , wherein the material comprises one or more precursor materials for forming a cermet via the self-propagating and/or self-sustaining reaction.

19 . The method as recited in claim 18 , wherein the cermet is characterized by either:
resistance to one or more types of radiation; and/or being a thermal insulator.
