If this tech makes it to industry I suspect it will make it to the inside high performance hydraulics before it makes it to the outside of ships. Those parts are already manufactured to high tolerances and operate in a chemically controlled environment. A little etching somewhere in a pump body or in a key place on an impeller to reduce friction by a percent or two could pay off big time over the life of the device.
