An inexpensive corrosion laboratory experiment suitable for all ages

摘要

One of the most obvious effects of corrosion is the damage that road salt can perpetrate on our vehicles. The author describes how to perform corrosion testing on several metals to demonstrate methods of effective corrosion protection and to make qualitative comparisons between protected and unprotected metals. Student reactions to the exercise are discussed and their suggestions for improvement are presented. Some photographs of the experimental results are shown. Additional photographs are provided in the electronic version of the paper.
