Where there’s silver, there’s tarnish. While getting the tarnish off your flatware might be an occasional inconvenience, to museum curators and conservators, it’s a threat to irreplaceable works of art.
To protect these objects for generations to come, scientists from the A. James Clark School of Engineering at the University of Maryland, College Park, have teamed up with conservators from the Walters Art Museum in Baltimore, Md., to develop and test a new, high-tech way to protect silver art objects and artifacts, using coatings that are mere nanometers thick.
The technique, called atomic layer deposition (ALD), will be used to create nanometer-thick, metal oxide films which, when applied to an artifact, are both transparent and optimized to reduce the rate of silver corrosion. The films are created when an object is exposed to two or more gases that react with its surface.
