Method for improving the extraction properties of a tributyl phosphate solution

Patent Martin, Earl C [Richland, WA]; Bruns, Lester E [Kennewick, WA]

A method for improving the extraction properties of a tributyl phosphate extractant used for reprocessing irradiated nuclear reactor fuel (Purex Process) containing degradation products of tributyl phosphate by contacting the extractant with diazomethane in a suitable solvent whereby the degradation products are esterified to triester phosphates which have extraction properties similar to those of tributyl phosphate.

Method For Improving The Oxidation Resistance Of Metal Substrates Coated With Thermal Barrier Coatings

Patent Thompson, Anthony Mark [Niskayuna, NY]; Gray, Dennis Michael [Delanson, NY]; Jackson, Melvin Robert [Niskayuna, NY]

A method for providing a protective coating on a metal-based substrate is disclosed. The method involves the application of an aluminum-rich mixture to the substrate to form a discontinuous layer of aluminum-rich particles, followed by the application of a second coating over the discontinuous layer of aluminum-rich particles. Aluminum diffuses from the aluminum-rich layer into the substrate, and into any bond coat layer which is subsequently applied. Related articles are also described.
