Patent ID: 8245661

Claim:
An apparatus for applying a coating to a surface of a structure, comprising: an iron-based amorphous metal material that will be applied as the coating to the surface, devitrified ferrite with said iron-based amorphous metal material which is considered an undesirable devitrified ferrite, a source unit of said iron-based amorphous metal material including said undesirable devitrified ferrite; an application system for directing said iron-based amorphous metal material including said undesirable devitrified ferrite located between said source unit and the surface of the structure, a spray stream of said iron-based amorphous metal material including said undesirable devitrified ferrite located between said application system and the structure, wherein said spray stream is used for coating the surface of the structure with said iron-based amorphous metal material; and a devitrified ferrite removal system operatively connected to said spray stream and located between said application system and the structure, said devitrified ferrite removal system including a magnetic field system for producing a magnetic field on said iron-based amorphous metal material in said spray stream between said application system and the structure, a diverted portion of said undesirable devitrified ferrite separated from said iron-based amorphous metal material in said spray stream, a collector positioned to receive said diverted portion of said undesirable devitrified ferrite that is separated from said iron-based amorphous metal material in said spray stream removing said diverted portion of said undesirable devitrified ferrite from said iron-based amorphous metal material in said spray stream, and a remaining portion of said spray stream with said diverted portion of said undesirable devitrified ferrite removed, wherein said remaining portion of said spray stream with said diverted portion of said undesirable devitrified ferrite removed is directed to the surface of the structure thereby providing the coating of said iron-based amorphous metal material on the surface of the structure wherein the coating is made of said iron-based amorphous metal with said diverted portion of said undesirable devitrified ferrite removed.
