Corrosion, the industry’s challenge

La corrosion est l’un des principaux défis auxquels l’industrie est confrontée dans pratiquement tous les secteurs. Selon l’AMPP (World Community of Corrosion Experts), ce phénomène de dégradation génère des pertes économiques équivalentes à 3 % du PIB mondial, avec...
What is corrosion?

What is corrosion?

Corrosion is the natural process by which metals tend to return to their oxidized state, the most stable form found in nature. Every day, enormous amounts of energy are invested to extract metals from their ores. However, once pure metal comes into contact with the...
Causes of Corrosion

Causes of Corrosion

The contact of a metallic material with oxygen and moisture triggers a complex electrochemical phenomenon. The presence of water in the environment promotes corrosion, while the reaction of metals with air causes their oxidation. In general terms, corrosion is the...
Types of Corrosion

Types of Corrosion

Corrosion occurs in the presence of aqueous solutions or electrolytes and is the main cause of metal degradation. Depending on their appearance and mechanism, the most common types of corrosion can be classified as follows: 1) Uniform corrosion It is the most common...
Corrosion Protection

Corrosion Protection

Cathodic protection is an effective method that involves polarizing the metal to a state of immunity to corrosion. Corrosion of structural steel has been proven to stop when its potential reaches -800 mV, measured with a silver/silver chloride (Ag/AgCl) reference...
