Abstract:
Described is a metal alloy comprising at least two metal elements which are not precious metals, said alloy being capable of forming a surface metal oxide layer that is conductive having a contact resistivity of 100 Ωcm or less after the alloy has been subjected to 125°C for 1008 hours. Also described is a process of preparing a metal alloy providing two metal elements which are not precious metals and oxidizing the metal alloy to produce a surface metal oxide layer that is conductive having a contact resistivity of 100 Ω-cm or less after the alloy has been subjected to 125°C for 1008 hours.
Abstract:
Described is an electrical contact comprising a conductive surface of nickel, tin, or a precious metal having a surface of formed grains and particles of a low friction polymer deposited on a portion of the grains wherein the resistance of the contact is about 1 ohm or less, measured at about 100 mA, and wherein the polymer particles are deposited on the grains from a dispersion of the particles in a liquid.
