Results obtained to date under this program have shown that many of the new, currently available, less polluting corrosion-protection systems are viable alternatives to currently used more polluting systems. Selection of a specific system for use in a given application would depend on the corrosion-protection requirements for theproduct being manufactured. Many of the systems selected for final evaluation and characterization in this program can provide corrosion protection equivalent to or superior to that for currently used systems. These new corrosion-protection systems also offer additional benefits such as less waste treatment, increased operational safety, lower energy consumption, longer service life and greater production output.

This protection is necessary to maximize the life-cycle of metallic parts. Protective coatings are the most effective means in terms of weight and cost for providing protection against galvanic and atmospheric corrosion. Many coatings that are currently in use, however, are formulated from toxic chemicals which, if not properly treated and controlled, can induce damaging effects in the environment. Mounting concern over eKvironmenta1 pollution and more stringent EPA and OSHA regulations have applied pressure on metalfinishers to consider new less polluting, corrosionprotection systems in lieu of currently used organic solvent paint systems and cyanide electroplating systems.
