830,328. Coating by vapour deposition; copper alloys. GENERAL ELECTRIC CO. May 22, 1958 [June 5, 1957], No. 16430/58. Classes 82(1) and 82(2) [Also in Groups XXII and XXXVI] Fig. 4 shows a device for coating a glass &c. surface 20 with an alloy of aluminium, iron, and copper which is in the form of a small metal turning placed on a vaporizing coil 19 connected to leads 26, 27. A quartz heater 23 connected to leads 24, 25 maintains the surface 20 at a temperature of 280‹C-300‹C. The air in the enclosure 21 is removed through a tube 22, and a current passed through the coil 19 to vaporize the alloy. The deposit on the surface 20 is cooled before being exposed to the air, as by passing nitrogen or other inert gas over the coated surface. Alloys. A vitreous body is coated with an alloy consisting of 6% to 11.2% of aluminum, 1.5% to 4.5% of iron, the balance being copper. |
