Abstract
Electroless underwater metal plating of a surface of fixed or floating structure is accomplished by transferring to the surface metal ions from a metal precursor in a solid or semisolid electrolyte that is pressed against and moved over a submerged surface. Metal ions from a metal salt blended in the solid or semisolid material plate the underwater substrate.
Claims19
A method comprising:
- underwater deposition of a metal on an underwater metal substrate in an underwater environment, further comprising:
- blending a metal precursor and a binder,
- molding the blended metal precursor and the binder,
- forming a block of the blended metal precursor and the binder having a desired shape,
- extending a handle from the molded block,
- pressing the block underwater against the underwater substrate in presence of fresh or saltwater in the underwater environment,
- moving the block underwater on the underwater substrate,
- transferring metal ions underwater from the metal precursor to the substrate, and
- plating the underwater substrate with the metal from the blended metal precursor without using an electrical power supply to trigger an electrochemical reaction while applying and attaching coatings underwater.

A method comprising:
- electroless plating a substrate with a metal underwater in an underwater environment by:
- blending a metal precursor and a polymer binder,
- molding the blended metal precursor and polymer binder into a block of solid or semisolid electrolyte predetermined shape,
- extending a handle from the molded block;
- pressing the block against an underwater substrate in presence of fresh or saltwater in the underwater environment,
- moving the block along the substrate,
- transferring the solid or semisolid electrolyte to the underwater substrate, and
