Abstract

Articles and/or devices formed by electroplating the amorphous phosphorous alloys co-deposited with particulate matter onto a substrate surface.
Claims25
A method of preparing an amorphous nickel phosphorous alloy, amorphous nickel cobalt phosphorous alloy or an amorphous cobalt phosphorous alloy having a phosphorus content of between 10% and about 20%, co-deposited with particulate matter, the method comprising:
- providing a bath consisting of nickel ions, cobalt ions, or combinations thereof, a sufficient amount phosphorous ions to produce an alloy having a phosphorous content of between about 10% and about 20%, and particulate matter mixed with an anionic or cationic surfactant;
- immersing a surface as a cathode into the bath;
- immersing an anode into the bath;
- and
- applying electrical potential across the anode and cathode so as to effect electrodeposition of the alloy onto the substrate to produce a coated substrate surface.
An amorphous nickel phosphorous alloy having a phosphorous content of between about 10% and about 20%, co-deposited with particulate matter produced by electrodeposition of the alloy.
An amorphous nickel cobalt phosphorous alloy having a phosphorous content of between about 10% and about 20% co-deposited with particulate matter produced by electrodeposition of the alloy.
An amorphous cobalt phosphorous alloy having a phosphorous content of between about 10% and about 20% co-deposited with particulate matter produced by electrodeposition of the alloy.
An article or device having a surface with an amorphous Ni/P alloy, amorphous Ni/Co/P alloy, or amorphous non-laminar Co/P alloy each having a phosphorous content between about 10% and about 20%, wherein said alloy is deposited thereon produced by electrodeposition of the alloy on the surface;
- and further comprising particulate matter co-deposited with the alloy.
