FIELD: technological processes. n SUBSTANCE: invention relates to the metallized articles from concrete production and can be used in the building materials industry. In the concrete products metallization method, including the concrete front surface plasma melting, first, performing the concrete front surface impregnation with the non-ferrous metal salt 20 % aqueous solution, and the subsequent plasma melting is performed by the electric arc plasma torch plasma torch jet with the passage speed of 0.35 m/s. n EFFECT: increase in the finished product quality by increase in the metallic coating to the substrate adhesion strength and frost resistance, the metallization process acceleration, reducing the production energy intensity. n 1 cl, 2 tbl, 1 ex |
