  • Patent number: 5747179
    Abstract: A method and apparatus for forming and consolidating organic matrix composites. An organic matrix composite panel comprising laid-up prepregs is placed between sheets of a susceptor material that is susceptible to inductive heating to form a workpiece. The resulting workpiece is placed within upper and lower dies formed of a material that is not susceptible to inductive heating. An induction coil embedded within the dies is energized and inductively heats the susceptor sheets surrounding the panel. The sheets in turn conductively heat the organic matrix composite panel. A pressure zone between the workpiece and one of the dies is pressurized to form the workpiece to the contour of a forming surface on one of the dies. The pressure in the pressure zone is maintained on the workpiece until the organic matrix composite panel is fully consolidated and formed.

  • Patent number: 5712049
    Abstract: A sliding element has a bearing metallic layer made of aluminum or an aluminum alloy which bears on its side facing the sliding surface a galvanically produced tin layer bonded to the bearing metallic layer by a very thin alkaline, halogen-free layer of zinc, copper, nickel and iron immersion deposited on the bearing metallic layer. To produce such sliding element, a highly-alkaline immersion bath is used containing salts of zinc, nickel, copper and iron mainly cyanide-based. After the immersion treatment, the sliding element blank is rinsed with considerably carbonic acid-free deionized water. During a first tinning step, the sliding element is treated in a bath at a temperature between and C. with a current intensity from 2 to 3 amperes/dm.sup.2 and for a duration of exposure of at least one minute.

  • Patent number: 5681663
    Abstract: An intermediate workpiece includes a first strip of laminated material exhibiting high thermal conductivity and which is subject to bowing in response to thermal cycling. A second strip of copper material is welded to the first strip along a longitudinal abutting edge of each strip. The first strip is partitioned into smaller heatspreader sections each for having a semiconductor die soldered thereto. Thermal manufacturing cycles will not cause a bowing of the second strip or of the heatspreader sections attached thereto.

  • Patent number: 5681662
    Abstract: A flexible circuit to interconnect two components of an electrical device is formed with a flexible polymeric substrate. A copper alloy is laminated to the flexible substrate. This copper alloy is processed to have relatively high strength, an ultimate tensile strength in excess of about 80 ksi, by either alloying additions, by processing or by a combination of the two. When such an alloy is laminated to the polymeric substrate, the resultant flexible circuit has improved (more cycles to failure) dynamic fatigue performance when compared to both pure copper and dilute copper alloys.

  • Patent number: 5681661
    Abstract: The performance of many macroscopic structures (those whose dimensions are on the order of centimeters, meters, or even larger) can be greatly improved by covering their surfaces with microstuctures. There are several applications in which "large," microstructure-covered sheets are useful. For example, dissimilar sheets of material that otherwise would not bond well to one another (such as a polymer and a metal) can be more strongly bonded with microstructures extending from one of the sheets and embedded into the other sheet. Such products make valuable laminate composites. As another example, the rate of heat transfer between an object and the surrounding medium can be dramatically changed (up or down) by covering the surface of the object with high aspect ratio microstructures, without significantly changing the component's size or weight.

  • Patent number: 5679471
    Abstract: A thin film silver-nickel coating for use as a protective coating on electrical terminals of separable electrical connectors. The silver-nickel coating is a silver-nickel nano-composite material characterized by silver and nickel grains having an average grain size of about five to about fifty nanometers, yielding a silver-rich phase and a harder nickel-rich phase as a result of silver and nickel being immiscible. In accordance with this invention, the volume fraction of nickel significantly influences the fretting wear resistance of the coating, with a preferred nickel content being resulting in the presence of disconnected islands of the nickel phase dispersed within a relatively softer silver matrix.

  • Patent number: 5674633
    Abstract: New composite-coated flat-rolled steel product and new methods of manufacture in which low-carbon steel, as received in cold-reduced continuous strip form is prepared for plating, a corrosion-prevention plating is applied, and a selected polymeric coating with lubricant is applied as the finish surface. The resulting composite-coated steel substrate is cold-rolled to decrease the composite-coated steel substrate gage. Selection of cold rolling steps, with non-use or selected use of stress-relief type of heat treatment before and/or after an initial cold-rolling of the steel substrate as received prior to surface preparation, provides for selective tin mill manufacture of composite-coated steel of various weights per unit area, for example, in the range of about 35 to about 100 lb/bb, produced by cold rolling of the composite-coated flat-rolled steel.
