Abstract
Plasma devices are provided, which in embodiments, comprise a surface and a cold-sprayed tantalum coating adhered to the surface, the coating configured to absorb a hydrogen species from an atmosphere comprising a plasma generated in the plasma device. Methods of making the coatings and using the plasma devices are also provided.
Claims18
A method comprising:
- generating a plasma within an inner volume of a container of a plasma device such that the plasma is surrounded by a gaseous region including a hydrogen species, wherein a coating including cold-sprayed tantalum is disposed on a surface of the inner volume;
- heating the plasma to a first temperature of at least about 500 K such that the coating absorbs at least a portion of the hydrogen species;
- cooling the plasma to a second temperature less than the first temperature such that the coating retains the absorbed portion of the hydrogen species;
- and
- heating the coating to a third temperature, the third temperature greater than the second temperature and less than or equal to about 1000 K such that the coating desorbs at least a portion of the hydrogen species to at least partially regenerate.
