ABSTRACT:
Apparatus to inhibit water pollution in surface treatment of metals, e.g., in coating base metal parts with an adherent coating of zinc, cadmium or similar protective metal by means of wet impact plating or electroplating, or in chromating or phosphating metal surfaces. A preferred embodiment relates to a wet impact plating process wherein the several solutions used in preparing the work, in plating it and in rinsing it are individually segregated after use and re-used in consecutive plating cycles so that release of ecologically objectionable effluent is eliminated and chemical and metal components fed into the process are conserved instead of being discarded after each plating cycle.
