By the measurement of weight changes with time, the extents of corrosion on specimens of mild steel, medium carbon steel, brass and aluminum exposed to the laboratory atmosphere and 0.1M solutions of sodium chloride, ammonium hydroxide and hydrochloric acid were obtained. These solutions, respectively, represent salt, basic and acid environments that are usually encountered by the test metals in actual service. Corrosion -time graphs were then drawn for each exposure environment to facilitate

A graphical illustration was further made to show the relative aggressiveness of the environments on any particular metal. Index Terms-Laboratory environments, mild steel, medium carbon steel, brass, aluminum. He has 19 years of teaching experience at university level. His areas of interest include thermo-fluids, building services, and corrosion control.
