Abstract

The invention provides a spray apparatus (10) for applying molten metal material (12) to an object (30) as well as a method of applying a cover (130) to the object which spray apparatus includes a housing (14) which has a sealable spray cavity (16), a pneumatic atomizer (20) in the cavity, feeder means (22) connected to the atomizer to supply the material to the atomizer, which feeder means has a furnace vessel (50) wherein the material is produced and a conduit (58) connected to both the vessel and the atomizer through which the material is delivered to the atomizer, heating means (54, 60) engaged with the feeder means and connectable to a power supply (66), air supply means (66) connected to the atomizer and a filtration device (78, 86, 96) which is in communication with the cavity in order to remove any excess material from the cavity.
