ABSTRACT:
Electrical contact device such as a terminal or a contact surface, has electrodeposited nickel thereon. The crystallites of the nickel are preferentially oriented with at least 50 percent of the volume {100} atomic planes substantially parallel to the contact surface. For many purposes, the preferentially oriented nickel surface is comparable to a gold plated contact surface.
