Abstract
A steel wire to be coated is brought across the graphite spout of a crucible filled with a bath of molten metal, after having first been heated in a tubular duct filled with protective gas by an electric coil powered by a high frequency source to a temperature lower than that of the molten metal contained in the spout. The melting point of this metal is greater than the austenizing temperature of the steel. On leaving the spout, the coated steel wire is then cooled in a controlled manner to avoid hardening, for example, if it is a question of a steel of approximately 0.7% carbon, by having it spend several seconds in a fluidized bed whose temperature is maintained at a temperature of the order of 550.degree.
