In a method of refurbishing a deposition target, a surface of the target
is provided in a process zone. An electrical arc is generated in the
process zone, and a consumable metal wire is inserted into the process
zone to form liquefied metal. A pressurized gas is injected into the
process zone to direct the liquefied metal toward the surface of the
target to splatter the liquefied metal on the surface, thereby forming a
coating having the metal on at least a portion of the surface of the
target that exhibits reduced contamination from the environment.
