Oysters May Treat Corrosion
Aviation Week & Space Technology 02/11/2008 , page 16
Researchers at the University of Dayton in Ohio are preparing an Air Force report showing the corrosion-protection potential that results from prodding oysters to produce pearl-like coatings on metals. Senior research scientist Doug Hansen says his team has manipulated oyster blood cells, prompting them to deposit nacre, a natural calcium carbonate ceramic, onto aluminum, titanium and stainless-steel alloys. The deposits are ?fracture resistant? and, as coatings, ?they can last a lifetime,? he says. The work is funded by the Air Force Office of Scientific Research.
