Zusammenfassung:	PCT No. PCT/SU80/00125 Sec. 371 Date Mar. 23, 1982 Sec. 102(e) Date Mar. 23, 1982 PCT Filed Jul. 31, 1980 PCT Pub. No. WO82/00479 PCT Pub. Date Feb. 18, 1982.An apparatus for making a brass-plated long-size article by a process for making a brass-plated long-size article comprises a bath 3 with molten inorganic salts, wherein the surface of a blank 1 is degreased and etched. Then the surface of the blank 1, after deposition of a layer of copper, is coated with a layer of zinc in a unit 8 for electrolytical coating of the surface of the blank 1 with a layer of zinc and thermodiffusive treatment and tempering of the blank 1 are effected in a bath 11 with molten salts.
