IR INFRARED RADIATION EMISSION SURFACE WITH HIGH THERMAL EMISSIVITY AND HIGH LIFETIME AND METHOD OF MANUFACTURING THE SAME

摘要

An infrared radiation emission surface IR in a predetermined wavelength range comprises a substrate (4) made of SiC silicon carbide material, and a set (8) of microstructures (10, 12, 14, 16, 18, 20, 22) lining the exposed emission face (6) of the substrate. Each microstructure (10, 12, 14, 16, 18, 20, 22) is formed by a single protrusion is disposed on and in one piece with the substrate (4). The microstructures (10, 12, 14, 16, 18, 20, 22) have the same shape and dimensions and are distributed on the face of the substrate (4) in a two-dimensional periodic pattern. The shape of each of each microstructure (10, 12, 14, 16, 18, 20, 22) is smooth and regular with a radius of curvature that varies continuously from the top of the microstructure to the emission face (6). ) exposed substrate (4).
