  • Patent number: 11578418
    Abstract: Silver electroplating compositions deposit silver with low coefficients of friction on substrates, such as nickel, copper and copper alloys. The silver deposits have coefficients of friction of less than or equal to 1 in contrast to many conventional silver deposits which typically have coefficients of friction greater than 1, such as 1.5. The silver deposits also have improved wear resistance in contrast to silver deposited from many conventional silver electroplating baths. The low coefficients of friction and improved wear resistance of silver deposited from the silver electroplating compositions is especially suitable for connectors and electronics finishes. Preferably, the silver electroplating compositions are cyanide-free silver electroplating compositions.
