*Required Fields

Surface treatment of metal film: Surface treatment of metal film. (Matsushita Electric Industrial Co., Ltd.In this study， 7440-02-0 and 7440-50-8 are also used., Japan). Jpn. Kokai Tokkyo Koho JP 59013081 A2 23 Jan 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C23F011-00; G11B005-72. APPLICATION: JP 82-123556 14 Jul 1982. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) Section cross-reference(s): 46 The metal film is coated with a surface-active agent and then contacted with a nonpolar solvent to prevent corrosion and reduce friction. Thus, a Cu film was coated with Megafac F110 [2795-39-3] in acetone and then contacted with C6H6. The treated film (0.32 friction coeff.) was exposed 1 wk in an atm. (90°, 90% relative humidity) without corrosion. .

Surface treatment of metal thin films to prevent corrosion and decrease friction: Surface treatment of metal thin films to prevent corrosion and decrease friction. (Matsushita Electric Industrial Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59009179 A2 18 Jan 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C23F011-00; G11B005-72. APPLICATION: JP 82-119456 8 Jul 1982. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) Section cross-reference(s): 77 Surface treatment agent(s) composed of org. compd(s). are made to adhere to thin film metals which are polished with an abrasive. The thin film metals are preferably Co-Ni alloys. The coating is uniform and thin and gives the metals a decreased dynamic friction coeff. and increased corrosion resistance. Thus, a poly(ethylene terephthalate) film 10 m-thick was coated with Co-Ni alloy [11101-13-6] 1500 ?-thick, coated with an acetone soln. 2991-51-7 and 11101-13-6 are also in the experiment. contg. C8F17SO3K 0.01 wt. % (Megafac F110 [2795-39-3]), and polished. The film had a dynamic friction coeff. of 0.30 and excellent corrosion resistance. .
