Titanium carbide coating film

Titanium carbide coating film. Kochi, Takeshi (Toyo Kogyo Co., Ltd., Japan). Japan. Kokai JP 52093700 6 Aug 1977 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C01B031-30. APPLICATION: JP 76-10655 2 Feb 1976. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) An Fe alloy contg. >0.3% C is heated in a mixt. of TiH2 2-10, K2TiF6 [16919-27-0] 2-7, SiC and/or Al2O3 10-25%, and alkali metal chloride balance at 900-1000° for 1-5 h. Thus, SK3 [12714-78-2] or SKD1 [12741-70-7] was heated in a mixt. of powd. TiH2 4.61, K2TiF6 4.64, SiC 21.6, NaCl 42.1, and KCl 27% at 950° for 3 h to coat with TiC to an av. thickness 34 or 25 m of Vickers hardness 1413-790 or 1800-2200 kg/mm2 resp. The Vickers hardness was lower than for the usual gas-phase process but had higher adhesion.

Recovery of metal values from ores, etc

Recovery of metal values from ores, etc. Smits, Peter Cornelius (ICI Australia Ltd., Aust.). Australian AU 480846 19 Mar 1975, 34 pp. (English). (Australia). CODEN: ALXXAP. CLASS: IC: C22B015-10. APPLICATION: AU 75-79302 10 Apr 1974. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) A method of treating a Cu-based alloy is described which consists of melting the alloys and inoculating the molten alloy with a compn. of B and Ti. The treated alloy demonstrates an increase in ultimate tensile strength, proof stress, elongation, compressive strength, hardness and fatigue resistance. The inoculant may be an alloy, such as Cu-B 5 or Cu-Ti 5. Preferably the inoculant incorporates KBF4 [14075-53-7] and K2TiF6 [16919-27-0], along with C2Cl6 [67-72-1] which can perform a useful scavenging function. The preferred B content is .ltoreq.0.2% while Ti is .ltoreq.0.3%.
