Abstract:

	When exposed to high-temperature, oxidizing environments, many refractory metals
form volatile oxides and erode at appreciable rates. Several noble metals are refractory
in nature but are far less susceptible to oxidation. Such metals can be electro-deposited
from aqueous solutions in thin coatings on various substrates to form oxidation barriers.
In this project, refractory metal structural devices will be protected in this way
to demonstrate that electro-deposition of noble metals can overcome the size, configuration,
and cost disadvantages of other fabrication techniques.

Potential Commercial Application:

Potential Commercial Applications: Noble metal coatings on refractory substrates
could be
applied to aircraft engine turbine blades, chemical reaction vessels, and liquid
metal handling and other corrosive chemical systems.
