Nickel plate resistance to seawater



2000

We are looking for technical information on the suitability of thick deposits of Sulphamate Nickel plating (0.020") on marine components subject to full and partial immersion in seawater. Any advice or direction to Technical papers on the subject would be appreciated.

Thanks

You will need to specify what the part will be doing. What the part is made of, how long do you want it to last.. what is the cost of premature failure. Is the equipment immersed part of the time, like in an intertidal zone, or being splashed like on a dock or on top of a buoy. Has anyone had a part like this in service before...etc.

The parts are mostly submarine hull penetrations which can be fully submerged or above the waterline. It appears that corrosion is quite evident for those areas above the waterline where wave splash leaves static seawater sitting for up to 6 months(during shipbuilding/maintenance).

Most are in contact with NiAlBronze valves, and some also with CuNi or stainless pipes. Underwater doesn't seem to be a problem. Used before in the Baltic sea. Very expensive to replace. It is a design specification. My company applied the Ni plating.
