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.
Claims7
A porous plate, comprising:
- a body having an upper major surface, a lower major surface opposite the upper major surface and minor sidewalls extending between respective entireties of the upper major surface and the lower major surface,
- the body being formed of porous material;
- and
- a metallic coating, which is thermally deposited onto an entirety of the minor sidewalls to form a thermal-sprayed or laser or plasma melted mechanical bond with the entirety of the minor sidewalls,
- wherein the metallic coating has a u-shaped cross section and comprises:
- a main sidewall member that extends along exterior edges of the minor sidewalls;
- an upper flange, which extends perpendicularly with respect to the main sidewall member and into the body from the main sidewall member and comprises an exterior surface flush with the upper major surface of the body;
- and
- a lower flange, which extends perpendicularly with respect to the main sidewall member and into the body from the main sidewall member and comprises an exterior surface flush with the lower major surface of the body.

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 major surface, a lower major surface opposite the upper major surface and minor sidewalls extending between respective entireties of the upper major surface and the lower major 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 minor sidewalls to form a thermal-sprayed or laser or plasma melted mechanical bond with the entirety of the minor sidewalls,
- wherein the metallic coating has a u-shaped cross section and comprises:
- a main sidewall member that extends along exterior edges of the minor sidewalls;
- an upper flange, which extends perpendicularly with respect to the main sidewall member and into the body from the main sidewall member and comprises an exterior surface flush with the upper major surface of the body;
- and
- a lower flange, which extends perpendicularly with respect to the main sidewall member and into the body from the main sidewall member and comprises an exterior surface flush with the lower major surface of the body.
