Principle of Electroless plating is same as Zinc or another electroplating.The principles of electroless nickel are not the same as electroplating.

edit1. makes awesome black coating for optics, decorative 2. Phosphorus alloyed to Nickel makes it hard and brittle making it a poor choice for protecting softer metals where physical strength is required. 3. I've mirrored (silvered) non-metallic surfaces easily but electroless nickel and electroless copper need a conductive surface for the red-ox reactions to occur. Palladium (stannous trichloride (-1))3 complex on glass epoxy board. Manganese diSulfide (reduction of perManganate cleaner) or colloidal carbon also used. 4. I always think of bronzing baby shoes when I think of electroless plating. 5. Other wiki reference displacement of copper by solution nickel as electroless. I have heard the term "electroless tin" for a thiourea/stannous sulfate/ sulfuric acid solution (thiourea forms a complex that lowers the redox potential of copper to below tin) that replaces surface copper atoms with tin. 6. Ionic Nickel is toxic. Nickel in stainless steel causes severe allergic reactions in a large human population (I think it was 6%), predominately in women. Nickel (phosphide) is not significantly more resistant to corrosion than nickel. 6. Saw Nickel and Borohydride system quoted in a forty year old industrial plating book. Our waste treatment group used a mod to reduce treated volume.

I removed the reference to iron oxide as a coating for hard disks, and added the most widely used alloy Cobalt=Platinum-Chromium. Also nickel was never used as a base coat here, only a top coat for wear resistance. In the Iron Oxide disks, electroless nickel was never used. —Preceding unsigned comment added by 68.107.186.155 (talk) 06:20, 8 August 2009 (UTC)
History needed
editWho, where, and when was it invented?
What is its history in industrial use? (What industry adopted it first, for what, and where did it go from there?) Phantom in ca (talk) 02:57, 14 June 2013 (UTC)
