Abstract
According to an aspect of the present disclosure, a porous plate is provided. The porous plate includes a body having an upper surface, a lower surface opposite the upper surface and sidewalls extending between respective entireties of the upper surface and the lower surface, the body being formed of porous material, and a metallic coating, which is thermally deposited onto an entirety of the sidewalls to form a high-strength mechanical bond with the entirety of the sidewalls.
Claims20
A porous plate, comprising:
- a body having an upper surface, a lower surface opposite the upper surface and sidewalls extending between respective entireties of the upper surface and the lower surface,
- the body being formed of porous material;
- and
- a metallic coating, which is thermally deposited onto an entirety of the sidewalls to form a high-strength mechanical bond with the entirety of the sidewalls.
A sublimator, comprising:
- a first layer through which a first fluid flows;
- a second layer through which a second fluid, which has a lower temperature than the first fluid, flows and removes heat from the first fluid;
- and
- a porous plate, which extends across a substantial entirety of the second layer and to which the second fluid comes into contact, the porous plate comprising:
- a body having an upper surface, a lower surface opposite the upper surface and sidewalls extending between respective entireties of the upper surface and the lower surface,
- the body being formed of material, which is porous to the second fluid;
- and
- a metallic coating, which is thermally deposited onto an entirety of the sidewalls to form a high-strength mechanical bond with the entirety of the sidewalls.
A method of sealing a porous plate of a sublimator, the method comprising:
- fashioning a porous material into a plate;
- masking areas of the plate that are not to be coated;
- sealing unmasked areas of the plate by thermally depositing metallic material onto the plate;
- and
- unmasking the areas of the plate that are not to be coated.
