Effects of salt and other contaminants on rate of rusting Print E-mail

ImageRusting is one of the most common ways of corrosion that damages and destroys metal structures such as cars, pipes, tanks, bridges and factories.
Rusting often creates hazardous side effects as well. For example rusted tanks and pipes leak and contaminate the soil, also rusted equipment may break and put human life at risk.
Every year billions of dollars are being invested in research and technologies to prevent rusting and other types of corrosion. Research on factors that may prevent, slow down or accelerate rusting is a valuable and educational experience.

Project description
This project is fairly easy and can be completed in 2 to 4 weeks, however spending more time offers a more accurate result. During this project the student needs to establish a method to measure the rate of rusting. Then samples of different metals must be tested under different chemical and physical conditions for rusting. Test results will be recorded in a table and also presented as charts and graphs. Metal scraps and different types of contaminants  can easily be found or obtained locally.
