The Effect of of Salinity, Temperature, and Rust Prevention Materials on the Corrosion of Steel

The purpose of this experiment was to measure what effect temperature, salinity concentration, and types of rust prevention materials have on the corrosion of steel. Hot rolled steel was used and coated with the proper rust preventing paint. Then the squares were massed before the tests. They were allowed to soak for 48 hours in the different concentrations of salt water, at varying temperatures, and coated with different rust preventing paints. The squares were massed again and to measure the amount of mass lost. A Design of Experiment, or DOE, test was used to analyze the data. The data and graphs show that rust prevention, the interactions between salinity and temperature, salinity and rust prevention, and temperature and rust prevention all had significant effects on the amount of mass lost.
