COATING, APPLIED ON METALLIC SURFACE AND INCREASING ITS RADIATION CAPABILITY AND METHOD OF ITS APPLICATION

摘要

FIELD: metallurgy. ^ SUBSTANCE: coating consists of 10-50 wt % of mineral SiO2-coupling agent and 50-90 wt %: of mineral filler. Method of plating includes heating of metallic surface up to temperature 100-350C and dispersion on it of suspension of specified coating. In the capacity of source of mineral SiO2-coupling agent it is used concentrated water sol of silicate. In the capacity of mineral filler there can be used powders of silica, mineral glass, zeolite. ^ EFFECT: increasing of emissivity and durability of coating, simplification of method of its application. ^ 18 cl, 2 dwg, 1 tbl
