Abstract

A system for coating a surface comprising providing a source of iron-based amorphous metal, the iron-based amorphous metal including devitrified ferrite; directing the iron-based amorphous metal toward the surface by a spray for coating the surface; and separating at least a portion of the devitrified ferrite from the spray before the spray reaches the surface. Also an apparatus for coating a surface comprising a source of iron-based amorphous metal, the iron-based amorphous metal including devitrified ferrite; an application system for directing the iron-based amorphous metal toward the surface by a spray for coating the surface, and a system for separating at least a portion of the devitrified ferrite from the spray before the spray reaches the surface.
