Corrosion

What is corrosion ?

The term indicates a natural and irreversible process of slow and continuous consumption of a material, with the consequent deterioration of the characteristics and / or physical properties of the material involved. This phenomenon occurs by a physical-chemical interaction of the material with the environment which surrounds it, mainly electrochemical interaction.

Corrosion affects only the metals?

Despite the term it is commonly associated to metallic materials, that is, to metals and their alloys, the phenomenon involves many other types of materials, also non-metallic; in general this emergence it can also be defined as a process of degradation and recomposition of the material in question with other elements present in the environment or with which it comes in contact.

Why do these tests?

The aim of the corrosion tests in salt spray or mist cyclic salt marshes, is to study, learn, highlight the differences and peculiarities of different materials, processes, treatments and coatings have on the start and on the development of corrosion, both on the surface in ‘intimacy of the tested materials.
