Abstract

The invention relates to the solar-to-heat energy conversion technology and can be used for the manufacture of heliothermal converters.The process for manufacturing a selective layer on a metallic surface for solar energy receivers includes application on the preliminarily cleaned metallic surface of a layer with the formation of microasperities, on the metallic surface of a thickness of 0,3…0,5 mm being applied aluminum by electric-arc deposition at the current intensity of 85…95 A and the voltage of 20…23 V, under a pressure of the compressed air of 1,8…2,0 MPa up to the obtaining of a layer with the thickness of 80…150 µm and the roughness of 55…60 µm.
