Methods of making multilayered, hydrogen-containing intermetallic structures
First Claim
Patent Images
1. A method of making a multilayered, hydrogen-containing intermetallic structure that releases thermal energy and produces a reaction product upon activation through an intermetallic reaction, the method comprising:
- depositing a first layer;
depositing a second layer, the first and second layers contacting each other and having respective compositions effective to undergo an intermetallic reaction when activated; and
introducing hydrogen into at least one of the first and second layers by plasma hydrogenation;
wherein the first and second layers are selected from the group consisting of;
a first layer of elemental Ti, and a second layer of elemental B;
a first layer of elemental C, and a second layer of elemental Ti;
a first layer of elemental C, and a second layer of elemental Zr; and
a first layer of elemental Zn, and a second layer of elemental Zr.

Abstract
Methods of making multilayered, hydrogen-containing intermetallic structures including at least two adjacent metal layers are disclosed. At least one of the metal layers contains hydrogen, which can be introduced into the metal by plasma hydrogenation. The intermetallic structures can have high hydrogen contents and micrometer-sized and nanometer-sized dimensions.
