RUST – The Enemy of All Car Owners Part 1 – Why Iron Rusts

Rust is the enemy of all car owners. Rust is that nasty brown stuff which destroys the bodywork of our cars, which causes our paintwork to bubble and blister, which is the downfall of our chassis and which causes our car to fail that vital MOT. Rust is the final dust into which our cars will crumble.

Rust is the oxide of iron that results from a chemical reaction: the oxidation of iron by atmospheric oxygen. There are in fact three kinds of iron oxides. These are known chemically as FeO, which is a black powder, Fe2O3 which is a brown-red powder, and Fe3O4 which is a mixture of the other two.

Iron will only rust in the presence of moisture. If you had an iron nail in a jar of oxygen with absolutely no moisture present the iron nail would never rust. Add some moisture and rusting will happen quite quickly, add a sprinkle of salt and it will happen very rapidly indeed.

When things go rusty a quite complex electro-chemical process is taking place. When iron is in contact with water that contains some dissolved oxygen, something called a solution tension is created. This will vary over the surface and will result in different electrical potentials. In the relatively electropositive regions the iron will dissolve forming positive iron II ions. At the electronegative regions negative hydroxyl ions (OH-) are formed. These react with the iron to form iron hydroxides which are insoluble. The iron II ions that are in solution react with hydrogen ions to form iron III ions which react with the hydroxide ions to form hydrated iron oxides. When these dry out they form rust. The greater the initial number of hydrogen ions (the lower the pH) and the more conductive the water (for instance the greater the concentration of road salt) the faster the rusting takes place.

When the rusting process has gone too far, the car parts that have corroded are irretrievable and will need to be replaced. Nowadays it is relatively easy to purchase these online, however prevention is better than cure and in the next article of this series we will examine ways to prevent rust. 

RUST – The Enemy of All Car Owners Part 2 – Rust Prevention

In part 1 of these articles we looked at why things rust and the chemistry of rusting. In this article we will look at some of the ways we can prevent rusting taking place and how to deal with rusted components. If the rust has gone too far then the car parts will need to be replaced, and although obtaining replacement parts online is relatively easy, it is better to prevent rust in the first place.

We have already shown that for rusting to take place there have to be three components present. These are iron, water and oxygen. If we can exclude any one of these then we will prevent rust. We also know that if the water is more acid and contains things like dissolved road salt then rusting will be more rapid.

One way to prevent rusting is to isolate these components, for instant using paint. Paints keep out moisture to a large extent, but they are not impenetrable by moisture. Good quality car paint will prevent moisture penetration for many years, but eventually, as it is subject to the rigours of heat, cold, surface abrasion by dust and atmospheric pollution it will become less resistant and allow moisture to penetrate. One way of helping paint maintain its protective properties is by refreshing the surface using wax.

Regular waxing of car paintwork is highly recommended and to ensure that this is maintained you should never allow the paint surface to become hydrophilic, it should always be hydrophobic. You can tell if this is the case by looking at water droplets on the paint surface. If they form tiny separate water droplets then you have a hydrophobic surface and are protected against rust, if the water droplets smear out into a film then the surface is hydrophobic and re-waxing is required.

The best way of waxing your car is to use a hand applied proprietary car wax rather than a wax additive in a car wash which are not as effective. First you should ensure that your car is spotlessly clean. Take a damp sponge and either smear it with wax or apply wax to the car surface. Apply the wax evenly over a section of the car. Let it sit for a few minutes, then polish it away.

How to Build Water Running Cars and Save Thousands on Gas and Diesel

More and more people are starting to realize that water running cars really do exist and it is possible to save thousands of dollars on gas or diesel. The truth is, this water technology has been around for roughly 90 years but greedy oil companies have tried to keep this technology underground for as long as they can.

Water is available to everyone and anyone with basic DIY skills can build a simple drive on water device and attach it to their vehicle’s engine, which will convert their gas guzzler into one of those water running cars. The technology that makes this all possible is very easy to understand.

Water is also known as H20 because it is made up of 2 parts hydrogen and 1 part oxygen. Although hydrogen gas is highly flammable, it burns at a much lower temperature than other fuels do. Since it burns at such a low temperature it adds to better fuel efficiency.

Using this drive on water device you will be able to separate the hydrogen from the water compound using a system of electrolysis. This separation will result in a gas known as HHO and it will combust when it is brought to it’s auto ignition temperature.

Building this run on water device to begin running your car on HHO gas is very straight forward. All the materials and components you need can easily be found for less than $50. Once you have installed it the device will use a small amount of electricity from your car battery to separate water into HHO gas. This HHO gas is %100 environmentally friendly and it burns cleanly and efficiently.

Some people prefer to buy an assembled run on water device but the companies that sell them charge up to $5,000 for each. Although these devices are well worth the money they can take more than a year to pay for themselves. This is why most people want to build one themselves instead of paying thousands for one that is already assembled.

To build a run on water device you will need a professional conversion guide to help you. A conversion guide will provide you with everything you need to get this project done such as a materials list, step by step instructions, and a diagram to display how everything should look. Some experts predict that by 2040 most people will be driving water running cars.
