ABSTRACT:
Compositions and methods for the introduction of alloying compounds into a metal substrate using a laser energy source is disclosed. The compositions comprise a viscous fluid mixture of a powdered silicate mineral composite, a powdered metallic or semi-metallic compound and a water insoluble or slightly water soluble liquid component capable of supporting a dispersion of the powdered silicate mineral composite and the powdered metallic or semi-metallic compound therein. The composition may be sprayed in bulk onto large surface areas of a metal substrate in need of repair prior to laser irradiation.
