摘要:
A lead structure for use with a magneto-resistive sensing element in a magnetic disk system is described. The lead structure comprises a layer of ruthenium or rhodium sandwiched between layers of a nickel-chromium alloy. The lower nickel-chromium layer acts as a seed layer to ensure that the ruthenium and rhodium layers have crystal structures that correspond to low resistivity phases. The interfaces between these three layers introduce a minimum of interfacial scattering of the conduction electrons thereby keeping dimensional increases in resistivity to a minimum.

The addition of small amounts of CeO2 and Cr to intermetallic compositions of NiAl and FeAl improves ductility, thermal stability, thermal shock resistance, and resistance to oxidation, sulphidization and carburization.
摘要:
A multi-layered metal plate with excellent damping capacity and particularly, to a multi-layered metal plate with excellent damping capacity and a method for manufacturing it, is less costly since the plate can be simply manufactured by simply attaching a thin plate on a main metal plate by the methods such as welding and the like, has excellent damping capacity and especially can be easily shaped. In addition, in the plate, the secondary plate is attached on one or both surfaces of the main metal plate.

Metal foils are soldered using a soldering material. The metal foils are disposed in layers and/or are wound in layers to form a honeycomb body. An aluminum content of the foils amounts to at least 6 wt. %. The material is based upon nickel and contains 17 to 23 wt. % chromium, 5 to 10 wt. % silicon, 18 to 20 wt. % iron, and less than 0.5 wt. % boron.

Techniques are provided for electrolessly depositing and electrodepositing CoWP barrier coating onto copper or copper alloys to prevent copper diffusion when forming layers on articles such as watch bracelets, watch cases, imitation jewelry, spectacle frames and metal buttons.
摘要:
Described is an article comprising a biaxially textured metal substrate and a layer of palladium deposited on at least one major surface of the metal substrate; wherein the palladium layer has desired in-plane and out-of-plane crystallographic orientations, which allow subsequent layers that are applied on the article to also have the desired orientations.
摘要:
A metallurgical product, such as brazing sheet, comprises a core, on at least one side of the core an interlayer bonded to the core and a cladding bonded to the interlayer. The core and the interlayer are a compositely cast material having at their mutual interface a bond formed in a casting process by their simultaneous solidification from contacting melts of their respective materials. This provides a simple process, with good adhesion. The cladding is applied subsequently and the composite material is rolled into a sheet or plate product.

A plated lead for electrical devices is plated with a Sn-based lead-free alloy containing 0.001-0.1 weight percent of Ga. The formation of oxides in a hot dipping bath can be suppressed by the presence of 0.001-0.1 weight percent of P in the alloy.

摘要:
A kind of composite metal coil/plate includes one parent metal coil/plate and at least one clad metal coil/plate as well as an interlayer composed of atoms of a brazing filler, the parent metal and the clad metal. The interlayer is about 2-10 &mgr;m in thickness. The present invention also relates to a method of manufacturing composite metal coil/plate. The method comprises pre-cladding the parent and clad metal coils/plates as well as the brazing filler foil in an inert or reductive atmosphere at 850-1000° C., and hot rolling cladding the same under inert or reductive atmosphere at 900-1050° C. A composite metal plate is obtained after cooling.
