Abstract: 549,485. Coating metals. HYGRADE SYLVANIA CORPORATION. Oct. 21, 1940, No. 15504. Convention date, Dec. 8, 1939. [Class 82 (ii)] [Also in Group XII] A steel matrix which is to be used in electrodes and other parts of electric discharge tubes is-provided with a firmly adherent coating of black iron oxide without hardening or embrittling it by heating it in an atmosphere containing hydrogen and products derived from, or similar to those derived from, the incomplete combustion of hydrocarbon gas or a mixture such as natural gas wherein the carbon monoxide and hydrogen components are adjusted in predetermined ratios to reduce unstable oxides and form the coating. The atmosphere contains a mixture of CO, CO 2  and H 2 , H 2 O, the H 2  content being above 50 per cent. of the H 2 , H 2 O and the CO content by less than 30 per cent. of the CO, CO 2 . In an example, the CO and hydrogen contents are present in about equal amounts, e.g. 7 per cent. of hydrogen and 6 per cent of CO. The parts to be treated are passed by a conveyer 14 through a muffle 7 heated by gas or electric heater 8 and provided with an inclined inlet 11 and outlet 12 surrounded by a water jacket 12. Gas and air are fed by pipes 1, 2 through a mixer 4 into a gas-cracking apparatus 5 containing a catalyser, the ratio of gas to air being adjusted by the valves 3. The products of combustion are passed through a cooler 6 to the inlets 9, 10 in the muffle. The heat treatment is carried out at a temperature of 750- 1200‹ C., and in the apparatus shown the material is passed through the muffle at a rate of 5-10 inches per minute, the temperature used being 1140‹ C.
