LOW-FRICTION ELECTRIC CONTACT

PROBLEM TO BE SOLVED: To provide an electric contact surface which provides corrosion resistance and oxidation resistance, and holds a low electric resistance in combination with decreased engaging/disengaging forces and the consequential wearing requisite. SOLUTION: The electric contact comprises a...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electric contact surface which provides corrosion resistance and oxidation resistance, and holds a low electric resistance in combination with decreased engaging/disengaging forces and the consequential wearing requisite. SOLUTION: The electric contact comprises a conductive surface of nickel, tin, or a precious metal having surfaces of formed grains and low-friction polymer particles deposited on part of the crystal grains. The resistance of the contact is about 1 ohm or less, measured at about 100 mA. The polymer particles are deposited on the crystal grains from a dispersion of the particles in a liquid.
