Abstract
A method of improving steel-backed antifriction alloy; composite strips and products therefrom, wherein the antifriction alloys previously deposited on the steel backing strip are subjected throughout the strip length to a spot-by-spot fusion operation performed by a highly-concentrated energy beam (electron or other), the intensity and displacement rate of said beam being adjusted in respect of the composite strip in such a manner as to afford a spot-by-spot fusion of the anti-friction alloys to a depth equal to the anti-friction layer thickness; and a method wherein concentration of said energy beam is adjusted so as to enable the mass surrounding any given melting spot to cause an abrupt cooling of said spot when the energy beam is moved to an adjoining spot.
