International Classification:

H01M 2/14
US Classification:

429 38, 429 32, 429 35, 429 39
Abstract:

A separator assembly for use in a stack of electrochemical cells is provided, having a first conductive metallic substrate with a first surface and a second conductive metallic substrate with a second surface, wherein each of the first and second surfaces are overlaid with an ultra-thin electrically conductive metal coating. The first and second surfaces form electrically conductive paths at regions where the metal coating of the first and second layer contact one another. The contact of the surfaces overlaid with metal coating is sufficient to join the first and second substrates to one another. Preferred metal coatings comprise gold (Au). Methods of making such separator assemblies are also provided.

Abstract:

A fixture device generally includes a base member, a reconfigurable pad comprising a shape memory material configured to selectively conform to a surface contour of a workpiece, and a thermoelectric unit in operative communication with the shape memory material of the reconfigurable pad. A process for operating a fixture device includes passing a current in a first direction through a thermoelectric unit in operative communication with a reconfigurable pad in an amount effective to heat a shape memory material therein to or above a shape setting temperature, contacting a surface of a workpiece with the reconfigurable pad, cooling the shape memory material below the shape setting temperature, and fixturing the workpiece with the fixture device.

Magnesium-Titanium Solid Solution Alloys

US Patent:

7651732, Jan 26, 2010
Filed:

Sep 7, 2007
Appl. No.:

11/851594
Inventors:

Yang T. Cheng - Troy MI, US
Mark W. Verbrugge - Troy MI, US
Michael P. Balogh - Novi MI, US
Daniel E. Rodak - Southfield MI, US
Michael Lukitsch - Marysville MI, US
Assignee:

GM Global Technology Operations, Inc. - Detroit MI
International Classification:

C23C 16/00
C23C 16/06
C23C 14/30
US Classification:

427250, 42725529, 42725532, 427595, 427596, 427597
Abstract:

Films of magnesium mixed with titanium are produced by non-equilibrium alloying processes such as electron beam evaporation of magnesium and titanium ingots in a very low pressure chamber. Such magnesium-titanium films form as single phase solid solutions. Titanium is inherently resistant to corrosion and its admixture with magnesium in solid solution provides a new composition that is less subject to intra-film galvanic corrosion. The magnesium-titanium films also provide relatively hard and strong coatings.
