Abstract

Process for electroplating, with high current densities of between 100 and 400 A/dm<2>, preferably between 200 and 300 A/dm<2>, in an electrolysis bath, of tin and/or tin alloys especially of Sn-Pb, Sn-Co and Sn-Ni alloys, on a metal substrate such as a steel strip, according to which an electrolysis bath is employed containing at least one halide, such as chloride, bromide or iodide, of the metal to be deposited on the metal substrate, and stannous and stannic ions, employing an electrolysis bath in which the content of metal ions is maintained between 60 and 150 g/l and is preferably of the order of 115 to 125 g/l in the case of tin plating and of the order of 135 to 145 g/l for the deposition of tin alloys, and in that the electrolyte is circulated at a velocity, relative to the metal substrate, of between 2 and 9 m/s and preferably between 3 and 6 m/s.
