Abstract

159,102. British Thomson - Houston Co., Ltd., (General Electric Co.). March 19, 1920. Cementation.-A surface alloy of chromium with a foundation metal such as iron, nickel, molybdenum, or tungsten, is produced by heating themetal in contact with powdered chromium at 1200 -1500‹ C. and under non-oxidizing conditions. The chromium &c. may be admixed with an inert material, such as alumina or magnesia, and a current of hydrogen may be passed through the receptacle during the process; or the receptacle may be evacuated. Decarbonizing occurs in the case of iron, and the carbon may be restored or increased by heating in contact with carbon or hydrocarbon gas. Specifications 17933/06 and 134,864 are referred to.
