Appl. No.:

11/168065

Inventors:

James H. Hawkins - Phoenix AZ, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

B05D 1/18
B05D 3/00
B05D 3/10

US Classification:

427309, 427327, 427409, 427435

Abstract:

A method for protecting from corrosion an element comprised of magnesium or a magnesium alloy comprises applying an adhesion promoter after applying a chromate solution to a surface of the element, whereby the chromate solution creates a corrosion-resistant chromate layer on the surface. The method further includes applying an organic coating, such as a resin seal, over the adhesion promoter so as to provide a seal from water and corrosive elements. The adhesion promoter provides improved adhesion between the chromate layer and the organic coating. Corrosion may be removed from the magnesium element before the application of the chromate solution.

Abstract:

In a general aspect, an electrical device assembly (e.g., a battery module) can include a first electrical contact surface, a second electrical contact surface, and a ribbon wire extending along a longitudinal axis. The ribbon wire can include a first portion, a second portion and a third portion. The first portion of the ribbon wire can be coupled with the first electrical contact surface via a first wedge bond. The second portion of the ribbon wire can be coupled with the second electrical contact surface via a second wedge bond. The third portion of the ribbon wire can extend between the first portion and the second portion. The first portion can have a first width transverse to the longitudinal axis of the ribbon wire, and the third portion can have a second width transverse to the longitudinal axis, the first width being greater than the second width.
