Abstract
654,228. Coating with metals; evaporation of metals. EDWARDS & CO. (LONDON), Ltd., W., HOLLAND, L. A., and CUTTER, J. M. Nov. 29, 1948, No. 30882. [Classes 82(i) and 82(ii)] In a method of vacuum evaporation of metals the metal in wire or tape form is presented axially towards an open end of an evaporator and intermittently moved into the evaporator by a predetermined amount, the metal being preheated and finally melted to allow discrete particles to flow over the inside of the evaporator and thereby be evaporated. As shown, a length of wire 11 from a spool 12 is fed by means of a tension pulley 16 and a feed pulley 15 through a guide tube 13 into an evaporator 14 which may be in the form of an electrically heated coiled tungsten wire. The wire 11 is preheated and then melted, the molten particles falling on to the coils from which they are evaporated and may be deposited on a moving or stationary article. The wire may be advanced an amount equal to the length of the evaporator by a fluid operated diaphragm 32 connected to a rack 39 and pinion, a ratchet 27 and pawl 28 preventing reverse movement of the feed pulley. Instead of a rack and pinion the feed pulley may be rotated by a capstan device, Fig. 6 (not shown). The diaphragm and its spring return may be mounted outside the vacuum chamber and the remainder of the apparatus inside. The rate of advance of the wire may be such that one length just melts as the molten metal from the previous length is completely evaporated. In a modification, Figs. 3 and 4 (not shown), a pair of supports may move relatively to one another with means for moving the wire forward but preventing backward movement, or a piston and cylinder similarly equipped may be used, Fig. 5, (not shown). Two or more wires of different metals may be used to produce an alloy coating, the wires being fed at the same or different rates. The Provisional Specification also states that the advancing gear may produce a nick on the wire to aid in quick severing.
