Abstract: The invention is directed to an article comprising a thin film of silver and/or copper contacted with a compound selected from the group consisting of a thiadiazole substituted by a mercapto group and/or an amino group and a triazole substituted by a mercapto and optionally an amino group. The invention is also directed to a method of protecting a silver and/or copper metallic film by contacting the film with a compound selected from the above group.

Abstract: In a heat wave-reflective or electrically conductive laminated structure composed of(A) a shaped solid substrate,(B) a transparent thin layer having a high refractive index in contact with one or both surfaces of a layer (C) below, wherein when the layer (B) is provided on both surfaces of the layer (C), it may, at one surface, be a transparent thin layer (B) whose refractive index is not high,(C) a transparent heat wave-reflective thin layer of an electrically conductive metal in contact with the substrate (A) or with the transparent thin layer (B), and(D) optionally, a transparent top layer; the improvement wherein said layer (C) is a layer composed of at least about 50% by weight of Ag, about 3 to about 30% by weight of Au and about 0.5 to about 30% of Cu, the amounts being based on the total weight of Ag, Au and Cu.

Abstract: Method and protective coating composition for preventing or minimizing costion or melting of titanium and combustible alloys thereof. Two layers of coatings are applied, the first layer preventing diffusion of the second layer into the titanium or alloy even at elevated temperatures, and the second layer suppressing titanium combustion. The first layer contains chromium, molybdenum, niobium, tantalum, vanadium, zirconium, platinum, or rhodium or a combination thereof or alloy of any of these metals. The second layer contains copper, aluminum, gold, nickel, silver, cobalt or a combination thereof or alloy of any of these metals. By preventing diffusion of the second layer into the substrate, the first layer prevents degradation of substrate engineering or mechanical properties.

Abstract: A solar heat absorber is produced by electrodepositing on a metallic substrate acting as a cathode in a plating bath a black coating including a ternary alloy represented by the formula:Sn--M--Mowhere M is Fe, Co or Ni. The electroplating bath contains a stannous salt, a salt of a metal M selected from the group consisting of cobalt, nickel and iron, a molybdate, an alkali metal pyrophosphate, and an amino acid or an ammonium salt of carboxlyic acid or mineral acid.

Abstract: Silver alloy wire for the production of jewelry, especially jewelry chains is made of a solder containing nucleus and a jacket of silver or silver alloy wherein the solder containing nucleus has a core of silver or silver alloy surrounded by a layer of brass.

Abstract: A new and improved magnetic recording disk can be prepared by interposing between an aluminum substrate disk and a recording alloy layer a support layer located on the substrate disk and a shield layer located between the support layer and the recording layer. The support layer is a hard, semi-crystalline nickel alloy layer having magnetic properties which is of such a character that if it is contacted by a recording head during the use of the disk it will tend to form a powder which will not interfere with subsequent use of the disk or recording head. The shield layer is of a nonmagnetic metal and serves to reflect signals from the recording head so that they do not reach the support layer.

Abstract: A novel fastening means of a highly corrosion resistant nature and presenting a bright chrome-like outer appearance.

Abstract: The material is applied to a substrate, for example, terminal bronze, brass, or the like, and comprises, preferably, 50 to 55% gold, 24 to 28% palladium, 15 to 20% silver, 2.5 to 3% tin, 0.08 to 0.15% iridium, 0.08 to 0.15% ruthenium, 0.1 to 0.3% copper and 0.6 to 1% indium.

Abstract: An SECo.sub.5 -permanent magnet composite of said permanent magnet bonded to at least one piece of iron wherein there is provided between said permanent magnet and the iron piece a metallic layer which is hard-soldered to both the permanent magnet and the iron piece, and wherein SE is an element having an atomic number of 58-71 or mixtures thereof.
