There is a general lack of knowledge about the definition of corrosion and the problems derived from it. As experts in the field, we have Corrosion and Coatings Inspectors certified by the World Corrosion Authority, NACE International.

What is corrosion?

Next, we offer you the definition of corrosion, as well as all the information necessary to make the most suitable coatings.

Corrosion is an electrochemical process that deteriorates metal by reacting with the environment. The corrosion process deteriorates the iron within the steel, implying the loss of its main characteristics such as hardness or resistance.

Ferric oxide or rust consumes the metal. It is the most common byproduct of corrosion and arises from adding oxygen.

The Corrosion Cell

There are certain elements that have to be present for the corrosion process to occur, without them, there would be no corrosion. These elements are known as The Corrosion Cell:

  • Anode: It is the part of the cell where the iron becomes another substance, that is, it is the area where oxidation occurs.
  • Cathode: Property reduction occurs at the cathode, while oxidation occurs at the anode.
  • Electrolyte: It conducts the ionic current. Examples of electrolyte: Water or the environment itself.
  • Metallic route: Or return path, is responsible for connecting the anode and the cathode to allow the passage of electrons generated in the anode to the cathode.

From COVER, understanding the operation of the metal oxidation process, we eliminate the components of the Corrosion Cell to control the deterioration of the materials

Factors Affecting Corrosion Rate

We can distinguish five factors that play a predominant role and affect the speed at which corrosion occurs in materials, such as: oxygen, temperature, chemical salts, humidity and pollutants and gases.

The galvanic series

We can distinguish five factors that play a predominant role and affect the speed at which corrosion occurs in materials, such as: oxygen, temperature, chemical salts, humidity and pollutants and gases.

Having said that, depending on the environment in which the materials are found, they will be under different factors that accelerate the oxidation process. Therefore, taking into account the environment to which they will be exposed, in addition to their potential for corrosion, at COVER we study the most suitable product, as well as the application that best suits the different coating needs and those of our clients.

Once all the necessary information about corrosion is known, we will explain you why Cover Systems S.L offers you the best coatings.
