Refractory Oxides
Ultramet has developed processes for fabricating coatings of the following refractory oxides (other oxides can also be deposited):
| Hafnium (HfO2) | Silicon (SiO2) |
| Zirconium (ZrO2) | Tantalum (Ta2O5) |
| Yttrium (Y2O3) | Titanium (TiO2) |
| Aluminum (Al2O3) |
Ultramet applies these refractory oxides by chemical vapor deposition as a 100% dense, pinhole-free coating on refractory metals, ceramics, and composites.
Used for resistance to high temperature oxidation and corrosion (e.g. sulfur and vanadium), these coatings can extend either the service life or operating temperature capability of many components, including rocket nozzles, piston heads and liners, turbine blades, and fuel-fired heat exchanger components.
