Electroplating of Zinc on Pipe Fittings

Electroplating of zinc on pipe fittings from a potassium chloride containing bath with brightener CT-2 was found to be a very good process with current efficiency of 95 pct and bright electroplate which has corossion resistance being almost the same as that of zinc electroplates on mild steel, which showed that the composition and the casting surface defaults of the pipe fittings had no significant effects on the quality of the electroplates. Therefore, electroplating of zinc on pipe fittings should be substituted for hot dipping process of zinc because the cost of zinc electroplating would be lower than that of hot dipping process due to the low er consumption of zinc and energy of the electroplating.
