Abstract

A technique which employs high-intensity, pulsed lasers to bond metallic foils to different metal substrates is reported. Laser-generated, large amplitude thermal and pressure waves heat and compress a coating /substrate combination and mix the two materials both by plastic or hydrodynamic motions, and by diffusion at rates determined by the elevated temperatures. The degree of mixing, the rate of cooling, and thus the depth, homogeneity and metallurgical structure of the bond depend on the laser intensity, fluence, and material properties. Optical microscopy and Robinson backscatter electron imaging of cross-sections of several such coatings indicate that they are unusually well-bonded, suggesting good resistance to abrasion and corrosion, and that they exhibit unique distributions of elements.
