Abstract
589,966. Coating metals. WESTERN ELECTRIC CO., Inc. Sept. 26, 1944, No. 18412. Convention date, Sept. 30, 1943. [Class 82 (ii)] In a method of plating metals with tungsten, chromium or molybdenum by decomposition of their carbonyls under reduced pressure, a total gaseous pressure of not more than three mm. of mercury is maintained during the process. As shown, the metallic carbonyls are led by U-tubes 15 and 16 into and out of a water-jacketed tube 10 having one end permanently closed and the other having a removable plug 14, the whole apparatus being mounted for heating in a high frequency coil 23. The outer tube 16 is attached to a vacuum pump and hydrogen may be passed into the tube 10 by a pipe 17b or through the pipe 15. The article 20 to be plated may be supported in the tube 10 by wedge-shaped pieces 21. A vessel 24 surrounding the U-tube 15 contains solid CO 2 during the evacuation of the tube 10 to a pressure of 0.1 to 0.2 mm. of mercury and when plating is started it is replaced by one containing warm water to volatilise the carbonyls. In a modification, 'Fig. 2, not shown, the interior of the tube may be the surface to be coated in which case it becomes the tube 10 and has one end connected to an end piece carrying the carbonyl tube and the other to an end piece attached to the vacuum pump either by cement or by flanges and gaskets, Figs. 3 and 4, not shown. In order to obtain even plating along the inner surface of a tube the carbonyl may be passed through a tube containing inlet and outlet holes and which may itself be water cooled, Fig. 5, not shown. An alloy of the coating metals may be applied by mixing their carbonyls in the U-tube. The Specification as open to inspection under Sect. 91 comprises also the deposition of carbides of the metals from the carbonyls. This subjectmatter does not appear in the Specification as accepted.
