Abstract
A technology is proposed for deposition of ceramic coating on the surface of Fechral porous matrix to improve the performance of infrared torches. Multichamber detonation device allows forming coatings on the working surface without any significant changes of its surface permeability. Presence of Al2O3 ceramic coating on the pore walls changes the burning mode. The flame front moves into the matrix to a small depth behind the coating film that leads to reduction of harmful emissions at fuel mixture combustion: carbon monoxide gas to the maximum, nitrogen oxide by 10…15 %. The effectiveness of matrix radiation increases up to 2 times in the spectral infrared range of wave length from 5 to 14 μm. 10 Ref., 2 Tabl., 5 Fig.
Keywords: porous metal matrices, infrared radiation, denotation spraying, ceramic coatings, harmful emissions, radiation effectiveness
