Claim:
1. A metal composite film, comprising a first component and a second component, wherein the first component is comprised of particles, the second component is a metal or metal alloy body, and the particles are distributed on a surface of the metal or metal alloy body and also incorporated within the metal or metal alloy body to a predetermined depth under the surface of the metal or metal alloy body such that a predetermined volumetric concentration of the incorporated particles varies continuously throughout the film from the surface of the body toward an opposite surface of the body so that the film has a tuned gradient of coefficient of thermal expansion values, wherein an electron beam produced by a superconducting linear electron accelerator is moved relative to the surface to locally melt the surface and the predetermined depth under the surface of the metal or metal alloy body to receive the particles.
