Based
on its unique characteristics and demonstrated performance, it represents a
new development in ceramic/glass science with excellent commercial potential
for a broad range of applications to include corrosion protection,
hydrophobic/non–wetting/nonstick surfaces, high temperature oxidation
protection, high emissivity coatings, protection for molten metal processing
equipment, and protective coatings for bioceramic materials. Current product
development efforts in collaboration with over 20 Fortune 500 companies are
targeted toward defense, energy, space, industrial, and consumer
applications. A new family of nanocomposite films and materials can be
produced with encapsulated nanoinclusions, within Cerablak™ matrix, of
varying chemistries to induce/enhance desirable optical, mechanical,
electrical, and chemical properties. Cerablak™ is resistant to
crystallization above 1400ºC and can be synthesized as a) hermetic films on
metal/alloy, glass, and ceramic substrates, b) nanocomposite powders, and c)
fibers, coatings, and matrices for CMCs. Using a low-cost, stable,
low-viscosity, and clear precursor solution, a dense, smooth, hermetic, and
transparent film can be produced on substrates by dip/spray/spin/brush/flow
coating techniques. A brief curing step above 500ºC is needed to form the
thermally stable "glassy" coating material. The key attribute of Cerablak™
is its low oxygen diffusivity (chemical diffusivity estimated to be ~ 1 x
10–10 cm2/sec at 1400ºC). In addition to high temperature oxidation
protection, Cerablak™ has been shown to protect against molten salt
corrosion. ATFI is exploring various product development opportunities along
with securing a strong intellectual property portfolio which includes two
issued US patents (US 6,036,762 & US 6,461,415) and several pending US and
international patent applications. Financial support from DOE, NSF, NASA, MDA, AFOSR, and industrial sponsors is gratefully acknowledged. |
