Metallization of concrete elements by thermal spraying for building and decorative applications calling for a metallised surface finish

摘要

The metallization, by thermal spraying, of concrete elements consists of spraying a molten metal on a surface to be metallised after preparation. The method consists of : (A) increasing the porosity, the surface hardness and the ductility of the concrete utilised during the production of the elements to be metallised, by using a fibred concrete; (B) treating the surfaces to be metallised; (C) spraying the molten metal with the aid of a thermal gun.
