Abstract
An arc spray apparatus includes a spray gun body with a pair of converging wire guides to guide two feeding metal wires to a region of contact at the wire tips where an arc melts the tips. A gas jet member has a projection extending forwardly from the gun body and offset laterally from a guide plane defined by the axes of the wire guides. The projection has a primary orifice to issue a primary gas jet directed laterally to the point of contact for atomization of the molten metal and production of a spray stream at an angle to the guide plane, preferably perpendicular. A plurality of at least four secondary orifices are arcuately spaced about the primary orifice. The secondary orifices effect secondary gas jets substantially parallel to the primary jet, so that the spray stream is constricted by the secondary gas jets.
