Reactive materials and thermal spray methods of making same

摘要

The present invention relates to reactive materials formed by thermal spray techniques. The thermally sprayed reactive materials have low porosity and high structural integrity. The reactive materials are useful for applications such as shaped charges, thermite welding, near net shaped components and the like.

主权项

1. A method of making a reactive material, the method comprising thermally spraying reactive components of the reactive material onto a substrate to build up a green body comprising the reactive components, wherein the reactive components are heated during the thermal spraying to a temperature below which they reach a fully molten state, and wherein at least a portion of the reactive components present in the green body after the thermal spraying step are exothermically reactive with each other upon subsequent heating of the reactive material to produce a heat of reaction of at least 1,000° C.
