HEAT RADIATING ELEMENT AND ITS FABRICATION METHOD Russian patent published in 2017 - IPC C23C4/04 C23C14/16 C23C14/46 C23C14/58 F28F13/00 

FIELD: heating.

SUBSTANCE: method contains arrangement of the grid on the base, made from the first metallic material, and forming the heat radiating cell on the base surface, either by spraying the granular particles, obtained from the second metallic material, the oxide of which has a reflection factor 70% or more, different from the first metallic material, and the particles from the second metal material oxide, either by deposition of metal particles, made from the second metallic material, and their oxidation, at that the formation is carried out so, that the cell contact area with the base is 1 mm² and less, after which the grid is removed. According to one more embodiment, the method includes forming of the heat radiating cell on the base surface by arc-ion deposition of metal particles, made from the second metallic material, with their distribution over the surface of the base material by applying the shift voltage, and subsequent oxidation of applied metal particles, at that the formation is carried out so, that the cell contact area with the base is 1 mm² and less.

EFFECT: increase of reliability and strength of the heat-radiating elements over a wide temperature range.
