Abstract

A product includes a material formed above 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. The product may include one, or multiple layers of the plurality of particles, and/or may include additional layers of a second material, which may be a non-energetic material. The particles may be configured to form a glass, an alloy, a ceramic, or a cermet upon completion of the self-propagating and/or self-sustaining reaction. The self-propagating and/or self-sustaining reaction may include an intermetallic reaction and/or a thermite reaction, may perform thermal work on the substrate, and/or may be completed in vacuum or an aqueous environment. A spatial configuration of the material, a structure in the substrate, and/or a symbol on surface(s) of the substrate may be formed upon completion of the self-propagating and/or self-sustaining reaction.

First claim

What is claimed is:

1 . A product, comprising:
a material formed above 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 product as recited in claim 1 , comprising at least two discrete layers of the material.

3 . The product as recited in claim 1 , further comprising one or more layers of a second material formed above the substrate.

4 . The product as recited in claim 3 , wherein the second material comprises a non-energetic material.

5 . The product as recited in claim 1 , wherein the product further comprises:
one or more additional layers of the material formed above the substrate; and one or more layers of a second material formed above the substrate.

6 . The product as recited in claim 5 , wherein the one or more additional layers of the material and the one or more layers of the second material form a structure comprising alternating layers of the material and the second material.

7 . The product as recited in claim 5 , wherein the second material comprises a non-energetic material.

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

9 . The product as recited in claim 1 , wherein the material comprises one or more precursor materials for forming an alloy via the self-propagating and/or self-sustaining reaction.

10 . The product 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.

11 . The product as recited in claim 10 , wherein the ceramic is characterized by either:
exhibiting resistance to one or more types of radiation; and/or being a thermal insulator.

12 . The product 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.

13 . The product as recited in claim 12 , wherein the cermet is characterized by either:
exhibiting resistance to one or more types of radiation; and/or being a thermal insulator.

14 . The product as recited in claim 1 , wherein the material comprises one or more compounds configured to render at least surface(s) of the substrate conductive upon completion of the self-propagating and/or self-sustaining reaction.

15 . The product as recited in claim 1 , wherein the self-propagating and/or self-sustaining reaction comprises either:
a thermite reaction; and/or an intermetallic reaction.

16 . The product as recited in claim 1 , wherein the material is formed above 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.

17 . The product as recited in claim 1 , wherein the material is formed above 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.

18 . The product as recited in claim 1 , wherein the plurality of particles are configured to complete the self-propagating and/or self-sustaining reaction in a vacuum.

19 . The product of claim 1 , wherein the plurality of particles are configured to complete the self-propagating and/or self-sustaining reaction in an aqueous environment.

20 . The product as recited in claim 1 , wherein the self-propagating and/or self-sustaining reaction performs thermal work and/or chemical work on the substrate upon initiation thereof.
