Action Corrosion provides Rust Removal products on the Sunshine Coast. Rust can often develop very fast. That’s why we are here. We provide products that allow you to professionally clean ferrous metals, i.e. iron, concrete and steel, from rust.
Rust from Water and Oxygen
Only when oxygen and water act on the iron and steel does rust form during this chemical reaction. Chemically, rust consists of a mixture of iron (II) oxide, iron (III) oxide and crystal water. The process that takes place is called oxygen corrosion.
The oxygen molecules penetrate the water molecules. They do not combine with the iron atoms but react with the water molecules and the iron electrons to form hydroxide ions. These are negatively charged and accumulate in the water.
The metal wants to compensate for the electron loss, and electrons flow in from the metal. This, in turn, creates a shortage of electrons. Positively charged iron atoms migrate into the water droplets and meet the negatively charged hydroxide ions there. The different charges cause the two to combine and form green to olive-brown iron (II) hydroxide.
Accelerated Rust Formation
Some specific metals and salts can accelerate the formation of rust. For example, if another metal touches the iron, a so-called local element is created at the point of contact. This leads to the oxidation of the less noble metal, in this case, iron.
Salts, in particular, increase the formation of rust because salts increase the conductivity of the water. As a result, the salts keep the current flow and the chemical reactions running permanently.
The salt ions ensure a permanent and accelerated charge equalization at the reaction sites. They promote the formation of hydroxide ions and the release of positive iron atoms. That is the reason why ships on Sunshine Coast are particularly susceptible to rust.
Rust-Like Oxidation and Corrosion Processes
There are also anhydrous oxidation products that can form on the surface of the iron. These form at high temperatures, such as during forging. These iron oxides are usually very thin and grey-black. This is the so-called hammer blow during forging, which flakes off the red-hot iron. Other rust-like appearances are the patina on copper or the white rust on zinc.
In contrast to rust with iron, the formation of white rust in zinc does not continue as soon as the moisture is gone. That is why you should always store galvanized sheet metal protected from the weather. With permanent exposure to moisture, zinc can also be gradually destroyed.
Can Stainless Steel Rust?
Stainless steel is known for the fact that it is protected against corrosion and that it cannot rust or rust as quickly. The alloy is a milestone in development that protects us from rust in everyday life, DIY, and handicrafts. But there is also stainless steel in different qualities. A4 stainless steel, for example, is more resistant than A2 stainless steel and is mainly used when a lot of water or additional salts drive the reaction process from steel/iron to rust.
