Arc spray uses electricity and the heat of a current arc to melt wire material. Arc thermal spray systems continuously feed two wires into a gun assembly where the wire is heated. These two wires can be the same material or two different materials. This includes the use of cored wire to form special alloys for better wear or corrosion characteristics. Compressed air propels the coating onto the desired surface creating a durable metal coating. Due to the high heat and spray velocity, arc coatings can be laid down quickly and economically.
