Abstract
A plurality of particles of oxide film forming metal randomly attached to portions of each other and a plurality of which are attached to a metallic substrate, the unconnected portions between particles defining porously interconnected open cell nucleation sites capable of aiding change of state from a liquid to a gas.
Claims8
A liquid heat exchanger interface comprising:
- a substrate;
- an open-cell porous coating of a passivating oxide film forming metal secured to the substrate, the coating comprising:
- a plurality of generally unflattened particles of which a plurality are mechanically interlocked to portions of each other, a plurality are adhesively attached through an oxide film to portions of each other, and a plurality are cohesively fused to portions of each other, a plurality of the particles having an oxidized surface, the unattached portions between particles defining a plurality of porously interconnected open nucleation cells and the attached particles defining a reticulated heat distribution structure.
A liquid heat exchanger interface comprising:
- a substrate;
- an open-cell porous coating of a passivating oxide film forming metal secured to the substrate, the coating comprising:
- a plurality of particles of which a plurality are cohesively attached at a liquid frozen interface to portions of each other, a plurality of particles mechanically interlocked with portions of each other, a plurality of particles attached through an oxide film to portions of each other, and a plurality of the particles having an oxidized surface, the unattached portions between particles defining a plurality of porously interconnected open nucleation cells and the cohesively attached particles in combination with the oxidized surfaces defining a reticulated heat distribution structure.
