Learning the kinds and causes of corrosion, and techniques on how to prevent, control and mitigate it is the first step in combating this process.

A variety of resources are avaialable for teachers and the public from the DoD Corrosion Policy and Oversight Website.

Corrosion at Play

Corrosion at Play is an interactive e-book for kids that teaches the basics of corrosion in a fun and easy way. It is designed to maximize retention and enhance learning by utilizing AAA high-quality graphics , interactivity, and a simulation game that will make their experience personal, relevant, and engaging.

Young Eric has just been given a new bike by his uncle. One day, Eric discovers his new bike is beginning to rust. Not only is the sight of rust unattractive but also more seriously, Eric finds out that it poses threat to his safety and health.

Read the full story and join Eric as he learns about the basics of material preparation. Prevent corrosion by interactively applying different coating systems. Be creative in restoring and customizing your items and find out how long you can protect them from corrosion!

CorrSim is a single-player, turn-based, computer simulation intended to teach students the environmental factors that cause corrosion on man-made structures, the consequences on the economy and what can be done to protect the aforementioned structures.

Protocol 424

Do you have what it takes to fight Corrosion? Find out here as you take on Protocol 424; an e-learning game where you will build, repair, and maintain infrastructures within an old R&D base.

Coin Battery

Stack metals togrther to make a battery.

Definition

Corrosion is the chemical reaction where metals break down slowly because of other elements in their environment. For example when you see a rusty car or bridge, corrosion is the cause. Rusting, a well known example of corrosion, is the breakdown of the metal iron.

Introduction

Every day bridges, automobiles, aircraft, and hundreds of other items made of metal corrode bit by bit. Produced for the DoD Corrosion Office by Bruno White Entertainment as part of a comprehensive series of  videos about corrosion, The Pervasive Menace describes the degradation process through sound and visual images. This video would be a great introduction to any lesson involving corrosion. Toby Nelson sings the haunting lyrics with music by Joel Simser. Daniel Dunmire and Lorri Nicholson served as executive producers and Sandy Cook producer. Pervasive Menace Lyrics

Corrosion Investigation (Worksheet pdf file)

Problem

What are the three conditions that cause iron to rust?

Materials

1. Four Test Tubes
2. One Test Tube Stopper
3. Four Iron Nails or Iron Shavings
4. Water
5. Oil
6. Salt

Procedure

Place an iron nail or iron shavings in each of the test tubes along with the designated ingredient(s). Place the test tubes on a shelf. Check in 24-48 hours to see if any rust has formed. Report your results on the worksheet.

Test Tube Conditions Results
1 Boiled Water and Oil Layer

 

2 Salt Water (electrolyte)

 

3 Air

 

4 Air and Calcium Chloride  

 

Conductivity Meter

Because saltwater is a better conductor than freshwater, the rate of metal corrosion is much higher in seawater. Corrosion of metal due to a stray electric current in water is referred to as stray current corrosion. This type of corrosion is particularly destructive in ports where a stray current can induce corrosion on multiple vessels as electrons flow from the metal, through the water, and into the ground. Corrosion prevention and control (CPC) is a significant part of the Navy’s budget (http://www.navsea.navy.mil).
