The Relative Corrosion Severity of Laboratory Environments on Mild Steel, Medium Carbon Steel, Brass and Aluminium
International Journal of Engineering and Technology
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
... ent to facilitate the assessment of the relative aggressiveness of each environment on the test metals. A graphical illustration was further made to show the relative aggressiveness of the environments on any particular metal.
